Cyanheads - MCP servers
We track 125 MCP servers from github.com/cyanheads: 124 actively maintained, 1,730 combined GitHub stars, oldest tracked repo from Dec 2024.
cyanheads publishes MCP servers we track in the official registry. Their portfolio spans science & health, maps & location, other and 10 more. First tracked publish 2025-09; most recent activity in the set 2026-07. Across their built pages, 495 releases shipped in the last 90 days. Notable servers on this site: obsidian-mcp-server, git-mcp-server, mcp-ts-core, mcp-ts-template, pubmed-mcp-server.
The code is written in TypeScript. You can install from npm. 37 servers also answer at a hosted remote endpoint, so there is nothing to run locally. 1,261 registry versions have been published in total, and the most recent commit across these repositories landed in Aug 2026. Every server listed below is re-checked each night against its source repository and the official MCP registry, so the dates and counts on this page reflect the latest verification rather than a one-time snapshot.
Together these servers expose 491 tools an agent can call, from 1 on the smallest to 29 on the largest. 54 need credentials in environment variables before they will run; the other 2 need none. 56 of the 56 publish install counts to a public registry, led by Ts Core at 51,396 in the last month. Ts Core has moved fastest lately, with 10 releases in the last 90 days. 37 also answer at a hosted endpoint, with nothing to install. The work spans 12 categories rather than one. Commits across these repositories run from Oct 2025 to Aug 2026.
