Adeu - Earlier Revision First-party
Dealfluence

DOCX redlining engine exposed as an MCP server, in Python and Node.js implementations: translates .docx files to a Markdown representation for LLM editing and applies edits back as native Word Track Changes. npm's latest @adeu/mcp-server is 2.4.0 (2026-08-13); the registry record trails at 1.7.1 (2026-05-16). No surface names a supported MCP revision. Resolved from the published package: @adeu/mcp-server 2.4.1 depends on @modelcontextprotocol/sdk@1.30.0, whose artifact implements 2025-11-25. This records what the artifact implements, not what a deployment negotiates.

Agent Swarm - Spec Support Unverified First-party
Desplega Labs

First-party Desplega Labs server for its own agent-swarm product, distributed as npm:@desplega.ai/agent-swarm and self-hosted: the registry declares the remote as https://{swarm_host}/mcp, where the operator supplies the host of their own instance, so there is no vendor endpoint to probe. Auth is a bearer API key plus an X-Agent-ID header naming a registered agent. No documentation names a supported MCP specification revision. Two protocol versions appear in source, both as defaults in code rather than support statements: an outbound MCP client wrapper defaults to 2025-03-26, and a dashboard-generated debug snippet hardcodes 2025-06-18. The declared streamable-http transport is a transport, not a revision.
agent-device - Earlier Revision First-party
Callstack

Callstack's CLI and MCP server for driving iOS, Android, TV, desktop, and web apps from coding agents, run locally via agent-device mcp over stdio. Its hand-rolled MCP implementation hard-codes protocol revision 2025-11-25 in the initialize handshake; 2026-07-28 support is not implemented.

AgentPhone - Spec Support Unverified First-party
AgentPhone

First-party AgentPhone server for its own telephony API, distributed as npm:agentphone-mcp and hosted by the vendor at https://mcp.agentphone.ai/mcp. Probed 2026-09-03: both server/discover at 2026-07-28 and a legacy initialize returned HTTP 401 {"error":"Missing Authorization header"}, which grounds the endpoint as live and bearer-gated but negotiates no revision, so spec support stays unknown. No documentation names a revision; the package depends on @modelcontextprotocol/sdk ^1.26.0. Identity drift worth noting: the registry name's trailing segment is "agentphone" while both the repository and the npm package are "agentphone-mcp", and the registry record pins 0.6.0 while npm ships 0.7.0.
AgentUtility Compose - Earlier Revision Publisher unverified

Amazon Bedrock AgentCore Gateway - Current Spec Verified First-party
Amazon Web Services

A managed AWS service rather than an installable server: each customer gets a per-tenant gateway endpoint and registers their own tool targets. Support for the 2026-07-28 revision is opt-in per gateway, enabled by calling UpdateGateway with the revision in supportedVersions. No source repository or package exists.

Apache SkyWalking MCP - Spec Support Unverified First-party
The Apache Software Foundation

The Apache SkyWalking project's own MCP server, a Go binary named swmcp that queries a SkyWalking OAP backend for traces, logs, metrics, topology and alarms. It serves stdio, streamable HTTP and legacy SSE, and authenticates to OAP rather than to its own callers. The 0.3.0 changelog entry on master says the server migrated to the official Go SDK and added support for the 2026-07-28 revision, but no 0.3.0 release is tagged: the newest tag is v0.2.0, so revision support is not yet recorded as shipped.
Apify MCP Server - Current Spec Verified First-party
Apify

Apify's first-party MCP server, hosted at mcp.apify.com over streamable HTTP, which exposes the Apify Store of scrapers and automations as MCP tools and can load an individual Actor's own MCP tools. Auth is OAuth or an Apify API token as a bearer header; an unauthenticated request to the endpoint returns 401. Endpoint probe confirmed support for 2026-07-28 via server/discover.

The Appium project's own MCP server for driving mobile automation sessions on iOS and Android, including test creation tools. Published from the appium GitHub organization; npm and the registry agree on 1.92.2 (2026-08-13). No project surface names a supported MCP revision. Resolved from the published package: appium-mcp 1.92.4 depends on @modelcontextprotocol/sdk@1.30.0, whose artifact implements 2025-11-25.

argocd-mcp - Spec Support Unverified Community
argoproj-labs

MCP server for Argo CD, distributed as npm:argocd-mcp and run over stdio, HTTP stream, or SSE; it is self-hosted only, with no vendor-managed remote endpoint. It lives in argoproj-labs, which the Argo Project's own governance README describes as "a separate GitHub org that we setup for community contributions related to the Argoproj ecosystem," administered by each project's owners and, per the labs org's own profile, "not part of the CNCF Argo umbrella projects." Argo CD's own repository and docs do not link the server. Its creators are named engineers from Akuity, a company founded by Argo CD's co-founders, but Akuity is not the vendor of Argo CD, which is a CNCF project. Authority is therefore community: verified maintainers, outside the project that owns the fronted service. No documentation names a supported MCP specification revision; the README's own curl example and a security-advisory proof of concept both hard-code protocolVersion 2024-11-05 in sample JSON-RPC payloads, which is example boilerplate rather than a stated capability. Auth is dual and asymmetric: ARGOCD_API_TOKEN authenticates the server outbound to Argo CD, while MCP_AUTH_TOKEN, added in v0.9.0, is an optional inbound bearer token required only once the listener binds beyond loopback; recorded here as api_key for the closest enum fit, since the enum has no dual-credential option. CVE-2026-82456 (CVSS 3.1 and 4.0 both 10.0, record published 2026-08-29) affected v0.8.0's unauthenticated, all-interfaces HTTP bind and is fixed in v0.9.0, released 2026-08-11, advisory GHSA-rp45-5x3v-48mr.

Ash AI MCP Server - Current Spec Verified First-party
Ash Framework

AshAi.Mcp.Server is a library module the ash_ai package (hex:ash_ai) ships for the Elixir Ash Framework; operators mount it themselves via forward "/mcp", AshAi.Mcp.Router, tools: [...], otp_app: :my_app in their own Phoenix router, or as a plain Plug in any Plug-based application, so there is no single hosted Ash AI MCP Server to point at, only per-deployment mounts of the same library code. It runs over the MCP Streamable HTTP transport only; its SSE support is an in-band response-encoding option within Streamable HTTP requests, not the deprecated standalone HTTP+SSE transport, which the source explicitly disclaims. Authentication defaults to none: the README's authentication section documents two opt-in options, "OAuth 2.1 - the right choice for 'remote' MCP clients that self-register and run the standard OAuth flow" via ash_authentication_oauth2_server, and "API keys - the quickest way to value when your clients are configured by hand with a static credential" via AshAuthentication.Strategy.ApiKey.Plug, and the router forwards without either configured by default. Both the shipped source (lib/ash_ai/mcp/server.ex at v1.0.3) and the live hexdocs page for the same module state, under "Protocol versions," that "the server supports multiple protocol revisions in tandem on the same endpoint": 2026-07-28, 2025-06-18, and 2025-03-26, grounding spec_status as current. The README's separate "Production MCP Server" section still states "The protocol version we implement is 2025-03-26," language the shipped v1.0.3 source and hexdocs supersede.

Authority is first-party on two AWS-controlled surfaces: GitHub reports the awslabs organization as verified ("is_verified": true, name "Amazon Web Services - Labs"), and the monorepo's own README describes the collection as "Open source MCP servers for AWS... A suite of specialized MCP servers that help you get the most out of AWS, wherever you use MCP." The server runs over stdio only, per the monorepo root README's transport statement ("The MCP servers in this repository are designed to support stdio only") and confirmed in source, where server.py calls mcp.run() with no transport argument. The auth enum has no clean match for this server's credential model: it authenticates to AWS through the AWS_PROFILE/AWS_REGION credential chain, requires an RDS Data API resource ARN carrying rds-data:ExecuteStatement permission, and separately authenticates to Postgres via IAM or username/password credentials held in AWS Secrets Manager and referenced by --secretManagerARN; api_key is recorded here for lack of a better enum value rather than as a literal description. The server is read-only by default; --allow_write_query disables that enforcement, and the README's own security section calls the mechanism "a best-effort, defense-in-depth mechanism, not a security boundary." Neither the README nor the docs site enumerates a tool list; tools_count 7 and the key_tools below were recovered by reading the source directly at https://raw.githubusercontent.com/awslabs/mcp/main/src/postgres-mcp-server/awslabs/postgres_mcp_server/server.py.

Browser Use MCP Server - Earlier Revision First-party
Browser Use

MCP server shipped inside the browser-use Python library for driving a real Chrome browser, run locally over stdio. The registry-published package launches the minimal --cli-mcp variant (browser_exec, browser_screenshot); the richer tool set documented on docs.browser-use.com runs behind the --mcp flag. No vendor documentation surface names a supported MCP revision. Resolved from the published package: browser-use 0.13.8 depends on mcp@1.26.0, whose artifact implements 2025-11-25. This records what the artifact implements, not what a deployment negotiates.

Google

Google's Chrome DevTools MCP server: lets a coding agent control and inspect a live Chrome browser with DevTools-grade debugging, performance tracing, and Puppeteer-based automation, run locally over stdio via npx chrome-devtools-mcp. Hand check 2026-08-25: no MCP revision statement in README, CHANGELOG or docs; @modelcontextprotocol/sdk 1.30.0 is a devDependency of a bundled build, so the SDK chain cannot ground a revision. v1.8.0 released 2026-08-25.

claude-flow - Earlier Revision Community
ruvnet

Community agent-orchestration harness by the developer rUv, exposing MCP tools for multi-agent workflows. Renamed to "ruflo" (repo ruvnet/ruflo, npm ruflo); the registry record still uses the claude-flow name at a September 2025 alpha. A critical unauthenticated RCE (CVE-2026-59726) was patched in ruflo 3.16.3. Checked 2026-08-25: the v3 MCP package README in the ruflo repository states "MCP 2025-11-25 Compliant - Standalone Model Context Protocol server implementation with full Resources, Prompts, and Tasks support". Both npm packages claude-flow and ruflo ship 3.38.20 from the same commit; releases 3.38.18 and 3.38.19 (2026-08-22) name MCP HTTP transport fixes.

CloudBase MCP - Spec Support Unverified First-party
Tencent CloudBase

First-party Tencent CloudBase server, distributed as npm:@cloudbase/cloudbase-mcp and also offered as a Tencent-hosted endpoint at tcb-api.cloud.tencent.com/mcp/v1, which requires an env_id parameter plus Tencent Cloud API key headers and so cannot be probed anonymously. Probed 2026-09-03: a GET answered HTTP 405 with a JSON-RPC error body and an uncredentialed server/discover answered HTTP 403 "Forbidden: Missing credentials", which grounds the endpoint as live and credential-gated without negotiating a revision. No documentation names a supported MCP specification revision; the package pins @modelcontextprotocol/sdk 1.30.0, which records what the artifact bundles rather than what the hosted deployment negotiates.
Cloudflare MCP servers - Current Spec Verified First-party
Cloudflare

Cloudflare's product-specific MCP servers, sixteen Cloudflare-hosted endpoints on mcp.cloudflare.com subdomains. Each request runs on a fresh stateless server with no protocol session. Historical /sse URLs survive as aliases to the same Streamable HTTP handler but no longer serve the deprecated HTTP+SSE transport. Authorization is OAuth with scope selection; the docs endpoint answers unauthenticated. A 2026-08-07 probe of docs.mcp.cloudflare.com/mcp answered server/discover at 2026-07-28 over streamable-http. Endpoint probe confirmed support for 2026-07-28 via server/discover.

Martin Vogel

Community MCP server (by developer Martin Vogel) that indexes a codebase into a persistent knowledge graph for AI agents, distributed as a static binary via npm or PyPI and run locally over stdio. Hand check 2026-08-25: no MCP revision statement in README or docs; ships as a native binary whose npm package declares no runtime dependencies, so no SDK chain exists.

Concord MCP - Spec Support Unverified First-party
Concord AI

Local-first coordination server distributed as npm:@concord-ai/concord-mcp, giving coding agents shared work-state across harnesses (Claude Code, Codex, Cursor, Gemini CLI, Grok Build) through five tools backed by a local SQLite store. It runs over stdio only, installed globally via npm and registered into each client's own MCP config by a `concord setup` command; no auth token or OAuth flow gates the MCP interface itself. The vendor's own site, getconcord.ai, links directly to this repository and instructs installing this exact package, establishing Concord AI as the vendor whose product the server fronts. No documentation names a supported MCP specification revision, so spec_status is unknown.
Containerization Assist - Earlier Revision Publisher unverified
Azure

Distributed as npm:containerization-assist-mcp. Resolved from the published package: containerization-assist-mcp 1.5.0 depends on @modelcontextprotocol/sdk@1.26.0, whose artifact implements 2025-11-25. This records what the artifact implements, not what a deployment negotiates.
Contentful MCP Server - Spec Support Unverified First-party
Contentful

Authority rests on the server living in the verified contentful GitHub organization, which GitHub's API reports with "is_verified": true, and on its publication under the @contentful npm scope; package.json for both workspace packages lists author "Contentful GmbH". The published package, @contentful/mcp-server, depends on a shared library, @contentful/mcp-tools, published from the same monorepo and versioned separately. No fetched page names an MCP protocol revision (README, CHANGELOG.md, and AGENTS.md were all checked); the @modelcontextprotocol/sdk ^1.26.0 dependency is a version range, not evidence of a specific revision, so spec_status is unknown. Vendor documentation on contentful.com was not verified this session: the domain returned HTTP 429 on every attempt, so authority and entity facts here rest on the GitHub org record, the README, package.json, and the advisory API rather than any contentful.com page.

Context7 - Current Spec Verified First-party
Upstash

Upstash's Context7 documentation server: pulls current, version-specific library docs into prompts. Hosted at mcp.context7.com/mcp with bearer API keys (anonymous use is rate-limited); also runs locally via npm. The 4.0.0 release of 2026-08-07 migrated to the 2026-07-28 revision, and an endpoint probe the same day confirmed it. Endpoint probe confirmed support for 2026-07-28 via server/discover.

Coroot - Spec Support Unverified First-party
Coroot

Coroot's MCP surface is a built-in feature of the Coroot product itself, not a separate package; it is served at /mcp on a customer's own Coroot instance, so no public remote_url applies. Coroot's docs describe the exposed surface (application topology, health signals, distributed traces, raw telemetry) and list 19 distinct tools, 2 marked Enterprise-Edition-only, without naming each tool individually on the fetched page, so key_tools is left empty here rather than guessed. Authentication is OAuth 2.0 with dynamic client registration (/oauth/register, /oauth/authorize, /oauth/token, /oauth/revoke, /.well-known/oauth-authorization-server), confirmed both in the docs ("Each user signs in with their own Coroot account on first connect, and the agent runs with that user's RBAC permissions") and in source. No fetched page names an MCP protocol revision; the go.mod dependency on github.com/mark3labs/mcp-go v0.45.0 is an SDK version, not evidence of revision support. CVE-2026-79786 (VulnCheck CNA, published 2026-08-25, CVSS 3.1 7.1 high) documents that the MCP OAuth registration endpoint validates redirect_uris with Go's url.Parse only, with no scheme or host allowlist, enabling open-redirect consent-phishing against authenticated users; affected versions 1.20.2 through 1.24.5. As of 2026-09-15 there is still no fix: api/mcp_oauth.go is unchanged at release v1.26.1 (published 2026-09-14) and on the current main branch (pushed 2026-09-15), and the file's last commit remains the 2026-05-05 change that introduced the MCP server. A proposed fix, PR #960, opened 2026-08-13 to add a scheme/host allowlist, was closed without merging. The public tracking issue, coroot/coroot#929, opened 2026-07-01, remains open with no maintainer fix committed.

Bytebase's universal database MCP server for PostgreSQL, MySQL, SQL Server, MariaDB, and SQLite, run locally via npx with a connection DSN. Supports a read-only mode and a bearer-token-authenticated HTTP transport. No vendor documentation surface names a supported MCP revision. Resolved from the published package: @bytebase/dbhub 1.2.0 depends on @modelcontextprotocol/server@2.0.0, whose artifact implements 2026-07-28.

dbx - Spec Support Unverified First-party
t8y2

Distributed as npm:@dbx-app/mcp-server. Hand check 2026-08-25: no MCP revision statement in the main or mcp-server package READMEs; the Rust server depends on rmcp 2.2.0 (Cargo.toml), not sufficient evidence on its own. Authority evidence: t8y2 is the sole npm maintainer (tongty.it@gmail.com) and owns the repository; dbx is the account's own product.
Decionis MCP - Spec Support Unverified First-party
Decionis

Decionis' own MCP server, distributed as npm:@decionis/mcp and documented on decionis.com/docs/protocol-mcp as "a local stdio MCP server that lets Claude Code, Codex, Cursor, and any MCP client... asks permission before it executes," which grounds first-party authority on a domain-verified vendor surface. The registry record's repository field cites https://github.com/decionis/agent-safe-pipeline, a real and active Decionis repository that does not contain this server's code anywhere in its tree; the repository that actually documents @decionis/mcp is a separate one, https://github.com/decionis/mcp, whose own README states the published npm package's source of truth lives in a private Decionis platform monorepo and that this public repo exists only to host setup guides, samples, and issue reports. repo_url below points at the latter, since it is where the server is actually documented. Probed 2026-09-15: a POST server/discover at protocol revision 2026-07-28 and a legacy POST initialize at 2025-11-25 against the documented remote endpoint both returned HTTP 401 with WWW-Authenticate: Bearer resource_metadata pointing at the endpoint's own oauth-protected-resource document, error invalid_token, and a JSON-RPC {-32001, "Unauthorized MCP request"} body. A separate plain GET against the same endpoint, sent without a JSON-RPC body, returned a self-descriptive JSON document advertising supported_protocol_versions up through 2025-11-25 at https://protocol.decionis.com/mcp; that document is advertised metadata, not a negotiated session, so spec_status stays unknown.

Doc Bridge - Spec Support Unverified First-party
AgentsKit.io

Resolves documentation ownership, edit roots and human handoffs before an agent edits code, distributed as npm:@agentskit/doc-bridge and launched via npx ak-docs mcp over stdio. First-party rests on four agreeing surfaces: the AgentsKit-io GitHub organization, the @agentskit npm scope, the doc-bridge.agentskit.io product page (which links only to this repository) and the parent agentskit.io site, which lists Doc Bridge among its own products. The dedicated docs/mcp.md page enumerates eight tools, while the README separately states a packaged bundle advertises fourteen; the extra six are not itemized anywhere fetched. The official MCP Registry record is pinned at version 1.2.6 from 2026-08-03, roughly forty releases behind npm's 1.7.45 as of 2026-08-29, and GitHub's own release feed stopped at v1.4.3. No file fetched, including the README, CHANGELOG and docs pages, names an MCP protocol revision, so spec support is recorded as unknown.

GitHub MCP Server - Current Spec Verified First-party
GitHub

GitHub's first-party MCP server: a GitHub-hosted remote endpoint at api.githubcopilot.com/mcp/ (OAuth, or a personal access token) plus a local Docker distribution over stdio. Toolsets cover repositories, issues, pull requests, and code analysis. Supports the stateless 2026-07-28 revision, shipped ahead of the revision's release on the official Go SDK.
GitLab MCP Server - Earlier Revision First-party
GitLab

GitLab's official MCP server, built into the GitLab application at /api/v4/mcp. GitLab docs state support for the 2025-03-26 and 2025-06-18 MCP protocol specifications was added in GitLab 18.7. Beta on all tiers of GitLab.com, Self-Managed, and Dedicated. No GitLab surface names 2026-07-28 support; a probe on 2026-08-14 answered with an OAuth challenge, so revision behavior is not observable without credentials.
gitlab-mcp - Earlier Revision Community
zereight

Community MCP server (by independent developer zereight) fronting the GitLab API: projects, merge requests, issues, pipelines, wiki, releases. Requires a GitLab personal access token by default, with OAuth modes for self-hosted remote deployments. Not published by GitLab, which operates its own official MCP server. No surface names a supported MCP revision. Resolved from the published package: @zereight/mcp-gitlab 2.1.49 depends on @modelcontextprotocol/sdk@1.30.0, whose artifact implements 2025-11-25. This records what the artifact implements, not what a deployment negotiates.

Distributed as npm:@gitkraken/gk. Authority resolved 2026-08-25: the repository is owned by the gitkraken GitHub organization and the npm package is maintained by axosoft (dev.subs@gitkraken.com); the MCP server is the CLI's own gk mcp subcommand wrapping git, GitHub, Jira actions and GitKraken APIs. No MCP revision statement in the README or the GitKraken help page for the MCP server (checked 2026-08-25).

Google Drive MCP - Spec Support Unverified Community
Piotr Agier

Community server for Google Workspace, distributed as npm:@piotr-agier/google-drive-mcp and self-hosted by the operator. The user supplies their own Google Cloud OAuth client, so the server holds no vendor credentials of its own. No documentation names a dated MCP specification revision: the deployment guide links the draft authorization specification for its team mode, which is the draft rather than a released revision, and the package depends on @modelcontextprotocol/sdk ^1.24.0, an SDK range. Published by an individual GitHub user with no Google affiliation, so authority is community despite the product names in the title.

homebutler - Current Spec Verified First-party
SangheeSon

Homelab management tool distributed as npm:homebutler, a thin installer (bin homebutler-mcp) that downloads a compiled Go binary rather than shipping an SDK-based JavaScript server; the package declares no @modelcontextprotocol/sdk dependency. It runs the MCP interface over stdio only, with no network port opened and no auth token, since the README states only the parent AI process can reach it over stdin/stdout. Vendor docs (docs/mcp-server.md, "Protocol versions") state that homebutler implements MCP revisions 2026-07-28, 2025-11-25, 2025-06-18, 2025-03-26 and 2024-11-05, which grounds spec_status as current with legacy support recorded for the four earlier revisions via matching support atoms.

Hostinger API MCP Server - Earlier Revision First-party
Hostinger

Hostinger's first-party MCP server for the Hostinger API, run locally from npm or used via the hosted remote at mcp.hostinger.com, which requires OAuth. No vendor surface names a supported MCP revision; a 2026-08-14 probe of the remote returned an OAuth challenge, so revision behavior is not observable without credentials. Resolved from the published package: hostinger-api-mcp 1.45.3 depends on @modelcontextprotocol/sdk@1.30.0, whose artifact implements 2025-11-25. This records what the artifact implements, not what a deployment negotiates.

Ignite UI Theming MCP Server - Spec Support Unverified First-party
Infragistics (Ignite UI)

Generates Sass palettes, typography, elevations and component themes for Infragistics' Ignite UI design system, distributed as the single npm package igniteui-theming, which bundles both the Sass library and the MCP server binary. The server runs over stdio only, launched with npx, and documents no authentication scheme. No README, changelog or registry manifest names a supported MCP specification revision; the resolved @modelcontextprotocol/sdk artifact implements up to protocol version 2025-11-25, but that is a fact about the underlying SDK build rather than a vendor statement about this server's own revision support, so spec_status stays unknown. The vendor's root README and its packages/mcp sub-package README disagree on tool count, eight versus twelve, a documentation drift rather than a protocol ambiguity.
ikeytz - Schlüsseldienst Ludwigsburg - Earlier Revision First-party
ikeytz - Schlüsseldienst Ludwigsburg

Fronts the operator's own locksmith business (ikeytz - Schlüsseldienst Ludwigsburg) as a remote streamable-http MCP server; no repository or GitHub presence was found for the operator. Probed 2026-09-15, a legacy initialize request with protocolVersion 2025-11-25 returned HTTP 200 with a matching negotiated protocolVersion, capabilities for tools, resources and prompts (listChanged false), and serverInfo name "ikeytz" version "1.0.0". The same session's POST of server/discover under Mcp-Protocol-Version 2026-07-28 returned HTTP 200 but a JSON-RPC error, method not found, so support for the current spec revision is not established. The server's own instructions string states that the published npm package @ikeytz/mcp is a command-line client rather than this HTTP server, so no package coordinate is recorded here. Authority rests on the domain-verified com.ikeytz registry namespace and a matching npm package author, tying the same registered operator to the business the server fronts.

IWE - Spec Support Unverified First-party
IWE

Turns a directory of markdown files into a knowledge graph that an editor's LSP and an AI agent's MCP client both read from, exposing fourteen tools for finding, creating, updating, querying and refactoring notes. It is distributed as the npm installer package @iwe-org/mcp, wrapping a Rust binary also published to crates.io as iwe, and runs over stdio by default with an optional self-hosted streamable-http mode. The HTTP mode binds to localhost by default and documents no built-in authentication, leaving TLS and access control to an external reverse proxy. No README, docs page, changelog or server.json names a supported MCP specification revision, so spec_status is unknown; the rmcp v3 dependency in the server's Cargo.toml is an SDK range, not a revision statement.

Community search aggregator distributed as npm:mcp-omnisearch, unifying four tools over seven third-party providers: Tavily, Brave, Kagi, Exa, Linkup, Firecrawl and GitHub.

No documentation, dependency file, or registry record names a supported MCP specification revision, so spec_status is unknown.

mcp-ssh-manager - Spec Support Unverified Community
Jérémy Christillin

Community SSH management server distributed as npm:mcp-ssh-manager, giving Claude Code and OpenAI Codex 37 tools across command execution, file transfer, backups, database operations and health monitoring on operator-configured remote hosts. It runs over stdio only; MCP-level auth is none, while a separate per-server security mode (unrestricted, readonly, or restricted with allow/deny regex patterns) gates which commands each configured SSH connection accepts. No documentation or dependency file names a supported MCP specification revision; the package's @modelcontextprotocol/sdk ^1.30.0 dependency is a version range, not evidence of a specific revision, so spec_status is unknown.

mcpcap

MCP server for analyzing PCAP network capture files, distributed on PyPI and run locally. Registry record and PyPI agree on 0.9.6. Hand check 2026-08-25: no MCP revision statement in README, docs or release notes; PyPI requires fastmcp>=2.12.2,<2.15.0, a third-party framework the SDK chain does not cover. Last release v0.9.6 on 2026-03-17.
MCPHub - Spec Support Unverified First-party
Saman

MCPHub is a self-hosted MCP gateway and control plane: it both consumes upstream MCP servers, configured through data/mcp_settings.json, and exposes its own MCP endpoints to AI clients. This atom describes the exposed surface only. Authority is recorded as first_party under the self-owned-project precedent: the repository, the docs site (docs.mcphub.app), and the product site (mcphub.app, listed as the repo's own homepage) are all controlled by the same individual maintainer, so MCPHub fronts no separate third-party vendor relationship for this record to misrepresent. The README describes the exposed routes generically as supporting "SSE / Streamable HTTP / stdio" without pinning transport to a single value; transports here record both streamable-http and sse-legacy rather than asserting one exclusively. Auth on the exposed endpoints is layered: a built-in OAuth 2.0 authorization server ("Both client and server modes for secure authentication"), bearer keys, and JWT + bcrypt for local dashboard accounts, with MCP endpoints requiring authentication by default unless Bearer Authentication is explicitly disabled. oauth is recorded as the primary auth value because the exposed endpoints carry a real embedded OAuth 2.0 authorization server, not only static bearer keys. As a client, MCPHub can also connect to upstream MCP servers over stdio, SSE, or streamable HTTP; that consumer role is not otherwise assessed here.

Microsoft Advertising MCP Server - Spec Support Unverified First-party
Microsoft

Microsoft's own remote-only MCP server for Microsoft Advertising, documented on Microsoft Advertising's Learn setup guide (ms.date 2026-07-22); no repository is linked from any fetched Microsoft Advertising or Learn page. Authority is first-party on two Microsoft-controlled surfaces: the Learn guide instructs readers to "Register an OAuth client and connect Microsoft Advertising MCP Server to supported AI clients," and the documented endpoint itself resolves on Microsoft's own bingads.microsoft.com domain. Probed 2026-09-15: a POST server/discover at protocol revision 2026-07-28 and a legacy POST initialize at 2025-11-25 both returned HTTP 401 with a WWW-Authenticate: Bearer challenge naming the endpoint's own RFC 9728 protected-resource metadata document, and a direct GET of that document confirmed the resource URL, two authorization servers, and the required scopes. Neither probe negotiated a specification revision, so spec_status stays unknown. No fetched page names a transport; the setup guide's only signal is a VS Code mcp.json snippet setting "type" to "http," so transports is left empty even though the endpoint plainly accepts JSON-RPC over HTTPS.

PageSpeed Insights MCP - Spec Support Unverified Community
ruslanlap

Wraps Google's PageSpeed Insights and Chrome UX Report APIs in six workflow tools for auditing web performance, replacing an earlier set of nineteen endpoint-shaped tools in a breaking rewrite shipped 2026-08-26. It is distributed as the npm package pagespeed-insights-mcp and runs over stdio only, launched via npx. Callers must supply their own Google API key through the required GOOGLE_API_KEY environment variable; the server has no MCP-level authentication of its own. No README, changelog or docs page names a supported MCP specification revision, so spec_status is unknown. The maintainer is an individual Ukraine-based developer publishing under a personal npm account, not Google, which sets the authority as community rather than first_party.

Native Rust engine behind a thin Node launcher. No MCP revision statement in README or docs (checked 2026-08-25).

Pink Pixel

Listed with a remote endpoint. Publisher corrected 2026-08-25: the maintainer is the Pink Pixel organization (pinkpixel-dev on GitHub; npm maintainer sizzlebop, admin@pinkpixel.dev); Smithery is the hosting platform for the remote deployment, not the author. Authority community: the server fronts DuckDuckGo search, which the publisher does not operate. No MCP revision statement found (README, CHANGELOG, src/index.ts checked 2026-08-25); package.json declares @modelcontextprotocol/sdk ^1.18.1, not sufficient on its own.

Playwright MCP - Spec Support Unverified First-party
Microsoft

Microsoft's Playwright MCP server: browser automation through structured accessibility snapshots rather than screenshots, run locally over stdio via npx @playwright/mcp. Hand check 2026-08-25: no MCP revision statement in the README or linked docs; @modelcontextprotocol/sdk ^1.25.2 appears only as a devDependency, so the SDK chain cannot ground a revision. Runs stdio by default, HTTP with --port.

pm-claude-skills - Spec Support Unverified Publisher unverified
mohitagw15856

Distributed as npm:pm-claude-skills. Hand check 2026-08-25: the product is a plain-markdown skills library (its README counts 1153 SKILL.md files) with two custom MCP adapters that use no MCP SDK; the stdio adapter echoes the client's requested protocolVersion with a '2024-11-05' fallback, which grounds no revision.

Distributed as npm:@microsoft/powerbi-modeling-mcp. Checked 2026-08-25: the README states "This MCP Server supports the Elicitation MCP protocol", linking the 2025-06-18 specification's elicitation section; no later revision is named anywhere in the repository. Public Preview with no GitHub releases; npm 0.5.0-beta.12 ships platform-specific binaries with no SDK runtime dependency. Authority: the repository is in the microsoft GitHub organization, the package under the @microsoft npm scope, and the registry namespace com.microsoft is DNS-verified by the official registry.
PraisonAI MCP Server - Spec Support Unverified First-party
Mervin Praison

Heavy-host MCP server package (pypi:praisonai-mcp), one of three MCP packages PraisonAI documents alongside a client (praisonaiagents[mcp]) and a light server (praisonai-code). Serves 86 tools, 7 resources, and 7 prompts via `praisonai-mcp serve` (or `praisonai mcp serve`) over stdio (default) or --transport http-stream at a default /mcp endpoint, gated by a single wildcard-scoped --api-key or a --keys-file of per-key scopes. The one Official MCP Registry record found (io.github.MervinPraison/praisonai, v2.3.42, stdio only) describes the older monolithic praisonai package, not this package, and is stale against current releases, so no registry_name is recorded here. No vendor page fetched this session names an MCP spec revision for this server role; the client transports page's "Protocol Revision: 2025-11-25" statement covers only the separate praisonaiagents MCP client class and does not speak for this package. Six CVE records have been filed against PraisonAI's MCP-adjacent code since 2026-08-25, spanning three surfaces: the pip praisonai HTTP-stream transport (three records), the pip praisonai UI host app's stdio-spawn client path (one record), and the separate npm praisonai TypeScript MCPServer (two records); all six are fixed in current releases.

ROS 2 MCP Server - Spec Support Unverified Community
WiseVision

Python MCP server bridging MCP clients to ROS 2 nodes, topics, services and actions over stdio, distributed as the Docker image mcp/ros2 in Docker's curated MCP catalog. No documentation names a supported MCP specification revision: the README links the 2025-06-18 prompts section to explain what prompts are, which is a pointer to the spec rather than a support claim, and the pyproject dependency mcp[cli]>=1.23.0 records an SDK floor, not a revision. The registry record is stale: the repository was renamed from mcp_server_ros_2 to ros2_mcp and its own server.json now declares io.github.wise-vision/ros2_mcp, while the published registry entry still carries the old name and version 1.0.0 from 2025-11-26.

SiYuan - Spec Support Unverified First-party
SiYuan

Built-in MCP server of the SiYuan note-taking application (siyuan-note/siyuan), shipped inside the same Go kernel binary used by the desktop, server, and Docker builds; there is no separate package to install. kernel/mcp/server.go (tag v3.8.3) registers `ginServer.POST("/mcp", model.CheckAuth, model.CheckAdminRole, model.CheckReadonly, serveHTTP(handler))`, plus matching GET and DELETE routes, as Streamable HTTP only; no stdio or SSE code path exists for this server. Auth is an API token, via an `Authorization: Token`/`Bearer` header or a `?token=` query parameter, or an existing session, gated to the Administrator role; the default tool-exposure policy found in source is allow with no overrides, so an authenticated administrator reaches the full tool set by default. The only revision-dated string found anywhere in the fetched surfaces is a source constant, `protocolVersion20260728 = "2026-07-28"`, used only to branch HTTP-handler behavior by request header; that is source code observed via static fetch, not a vendor statement, docs page, or live probe, so spec_status stays unknown. No SiYuan user-guide page for the MCP feature could be fetched: b3log.org/siyuan does not mention MCP and a guessed English-language doc path returned HTTP 404 (COULD NOT VERIFY). The v3.8.0 changelog, published 2026-08-12, announced "Support Model Context Protocol (MCP)" as a new feature, though repository security advisories show the underlying route already existed and was exploitable at v3.7.1, released 2026-07-04, over a month before that changelog entry.

This records what the artifact implements, not what a deployment negotiates.
Snyk MCP Server - Earlier Revision First-party
Snyk

Snyk's MCP server ships inside the Snyk CLI and runs via the snyk mcp command, exposing Snyk security scans (open source, code, IaC, container, SBOM, secrets) to agentic tools. Checked 2026-08-25: the studio-mcp repository ships MCP specification conformance tests stating they "verify compliance with the Model Context Protocol specification" for versions 2025-11-25 and 2025-06-18 (internal/mcp/mcp_spec_conformance_test.go). The server is a Go binary inside the Snyk CLI, invoked as snyk mcp and built on mark3labs/mcp-go v0.31.0; the npm snyk package itself declares no MCP SDK dependency.

Splunk MCP Server - Earlier Revision First-party
Splunk

Splunk publishes the Splunk MCP Server app (Splunkbase uid 7931, appid Splunk_MCP_Server) as an installable Splunkbase package for a customer's own Splunk Search Head or Search Head Cluster; there is no Splunk-hosted public endpoint and no linked source repository on the advisory, the CVE record, or the Splunkbase listing. The app's 1.3.1 release entry (published 2026-08-03 per the Splunkbase release API) states "Updated MCP protocol version to 2025-11-25," a vendor release note naming a revision, so spec_status is legacy with latest_spec 2025-11-25 and a matching support edge; no fetched page ties a revision to the current 2.0.0 release, and no page names 2026-07-28.

ssh-mcp - Spec Support Unverified Community
Tufan Tunç

Community SSH server distributed as npm:ssh-mcp, running over stdio by default with an optional bearer-token HTTP transport. Destructive and privileged commands are gated behind an MCP elicitation prompt, and the README states that a client without elicitation support has every such command refused rather than silently allowed. No documentation names a supported MCP specification revision; the package depends on @modelcontextprotocol/sdk ^1.30.0, which is an SDK range rather than a revision. The repository has published six security advisories between 2026-08-09 and 2026-09-02, five of them variations on the same defect: the command classifier that enforces read-only mode and the approval gate can be fed a command it misreads.

TikTok for Business MCP Server - Spec Support Unverified First-party
TikTok

TikTok's first-party MCP server for the TikTok Ads platform, documented on business-api.tiktok.com as packaging roughly 400 TikTok API for Business endpoints as MCP tools. It is served at two paths under /open_mcp/: tt-ads-mcp-flat loads the full tool set at connection time, and tt-ads-mcp-layer loads around 40 core tools with the rest discoverable on demand. Tokens are scoped per path. Authorization is OAuth 2.0 with dynamic client registration and PKCE (S256), access tokens valid 24 hours and refresh tokens 30 days. No TikTok surface names a supported MCP revision, so spec support is unverified.

No MCP revision statement found (checked 2026-08-27).

Weather MCP Server - Spec Support Unverified Community
isdaniel

Distributed as pypi:mcp-weather-server. Authority resolved 2026-08-25: the publisher is the personal GitHub account isdaniel (PING-HSIU SHIH) and the server fronts the third-party Open-Meteo API, which the publisher does not operate. No MCP revision statement found (checked 2026-08-25): the README's "latest MCP Streamable HTTP specification" names no revision, and server.json's $schema date is the registry server schema, not a spec revision. PyPI requires mcp[cli]>=1.12.0, an ambiguous range.

WebCrypt MCP Server - Earlier Revision First-party
putervision

A self-contained cryptography toolkit and MCP server offering AES-256-GCM, RSA-4096, ECDH, ECDSA/HMAC and post-quantum Kyber/Dilithium operations, all executed locally through the native Web Crypto API with zero runtime dependencies. It is distributed as the npm package webcrypt, invoked over stdio via npx, and documents no MCP-level authentication since every operation runs in-process with no network calls. The server implements its own hand-rolled JSON-RPC 2.0 stdio framing rather than wrapping an SDK. Its own docs/ARCHITECTURE.md states that WebCrypt "introduces a zero-dependency Model Context Protocol (MCP) stdio server conforming to JSON-RPC 2.0 and specification 2024-11-05," a vendor-authored statement naming an early spec revision, so spec_status is legacy with latest_spec 2024-11-05, several revisions behind the current 2026-07-28.
