mcp-omnisearch

mcp-omnisearch gives a single MCP interface to seven external search and extraction services: Tavily, Brave, Kagi (including Kagi FastGPT), Exa AI, Linkup, Firecrawl, and GitHub code search via the octokit dependency. It exposes four tools, web_search, ai_search, github_search and web_extract, over stdio only; there is no remote or streamable-http transport. Authentication is per-provider: the operator sets whichever of TAVILY_API_KEY, KAGI_API_KEY, BRAVE_API_KEY, GITHUB_API_KEY, EXA_API_KEY, LINKUP_API_KEY or FIRECRAWL_API_KEY it has, and providers without a configured key are skipped rather than causing an error.

The server is maintained by Scott Spence (GitHub account spences10), an individual developer whose public profile and blog show no affiliation with any of the seven providers it wraps. The io.github.spences10 registry namespace only verifies control of that GitHub account, not any vendor relationship, so authority is community rather than first_party for any of the fronted services.

No spec revision is named anywhere in the README, docs, package.json or the registry record. The official registry entry is also stale: it still reflects version 0.0.15, published 2025-09-10, while npm has since shipped to 0.1.0 (published 2026-08-25) and at least fifteen further version bumps; the repository's own committed server.json still targets the older 2025-07-09 schema rather than the 2025-09-29 schema the live registry API now serves. No security advisories have been published against the repository.
