MCP News catalogs 3 MCP entities (2 servers, 1 clients) with verified facts: 2 verified on the current spec revision (2026-07-28), 2 verified first-party servers.
MongoDB published mongodb-mcp-server v2.0.0, removing session state and requiring an explicit connection id on all database operations. The release also adds multi-region and customer-managed-key options to cluster creation and rejects unrecognized tool arguments. The notes name no spec revision.
A self-submitted pull request removed Tadas Antanavicius from the Registry Working Group leads list, merged on August 2. The stated reason is freeing time for two adjacent catalog projects, AI Catalog and Server Cards. The same maintainer authored the organization-namespace authorization fix in registry v1.8.0.
server releaseThe Ruby SDK reached v1.0.0 on July 24, declaring its public API stable, picked up the 2026-07-28 revision in v1.1.0 on August 1, and was promoted from Tier 3 to Tier 2 in the official SDK listing on August 2.
adoptionVercel's first-party MCP server at mcp.vercel.com now supports the stateless 2026-07-28 specification, serving newer clients the stateless request model while 2025-era clients keep working from the same endpoint, via MCP SDK v2 and mcp-handler 2.0.
Every story carries primary sources and a verification date.
Vercel published mcp-handler 2.0.0, serving the stateless 2026-07-28 protocol natively while keeping a compatibility layer for 2025-era Streamable HTTP clients. The release removes the legacy HTTP+SSE transport outright and turns the Redis dependency and session options into deprecated no-ops. It is a different artifact from the Vercel MCP server.
adoptionGitHub moved MCP server connections and agent skills for Copilot code review from public preview to general availability across its paid Copilot tiers. Tool calls made during a review are constrained to read-only, and the GitHub and Playwright MCP servers are enabled by default.
securityHashiCorp published two security bulletins one day apart covering its Terraform MCP Server and Consul MCP Server. In both products the stateless-mode issue is a cross-tenant credential reuse flaw that the GitHub advisory records score CVSS 10.0. HashiCorp's own bulletins state no CVSS scores or severity labels.
adoptionAWS shipped same-day support for the stateless MCP revision in AgentCore Gateway: gateways advertise the protocol versions they speak, clients select a version per request, and existing 2025-era clients keep working unchanged.
spec releaseThe Model Context Protocol's 2026-07-28 revision is stable: the protocol core becomes stateless, retiring the initialize handshake and protocol-level sessions, with Multi Round-Trip Requests replacing server-initiated requests and a formal twelve-month deprecation policy. All four Tier 1 SDKs shipped support on release day.
client releaseAnthropic published a post on the day of the revision describing the Claude-side capabilities tied to it and stating that support is being rolled out across Claude products. The post names four capabilities and puts the connectors directory above 950 servers, but gives no per-surface availability or completion date.

MCP server · by github · verified
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.
MCP server · by vercel · verified
Vercel's first-party hosted MCP server: docs search, project and deployment management, log analysis, and Web Analytics queries. Serves the stateless 2026-07-28 revision and 2025-era clients from the same endpoint, with OAuth authorization.
MCP News is a factual catalog of Model Context Protocol servers and clients plus a primary-sourced news feed for the MCP ecosystem. Every record carries source URLs, a verification date, and a calibrated confidence score, so claims like "first-party server" or "supports the 2026-07-28 stateless revision" can be checked rather than guessed at. Records that fall below the publishing threshold stay in moderation and never appear here.
