Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

cyanheads
cyanheads_describe_entry
Return the description and install snippets for a named tool or server. For tools: the description, owning server, and connection metadata. For either kind: local (stdio, via npx) install snippets for every published server, plus remote (HTTP) connection snippets when a hosted endpoint exists — for every supported client, or one client via the client parameter.
cyanheads_search_catalog
Search fleet tools and servers by natural-language description. Returns ranked matches with brief summaries and the server each tool belongs to. Use scope "servers" to find which server handles a workflow; use the default scope "tools" to find specific tools.

Cyanheads MCP Server — questions

Answers built from our own checks of this server.

What can Cyanheads MCP Server do?
It exposes 2 tools, read directly from the server on our last check. Among them: cyanheads_describe_entry, cyanheads_search_catalog. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Cyanheads MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 599 ms. The bar chart above shows every period we have measured.
How do I connect Cyanheads MCP Server?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Cyanheads MCP Server need an API key?
No. Cyanheads MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Cyanheads MCP Server?
It answers our handshake in 599 ms on average, which is faster than 18% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Cyanheads MCP Server?
The npm package @cyanheads/cyanheads-mcp-server was installed 679 times in the last week. Week over week that is +728%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Cyanheads MCP Server open source?
The code is open source: it is published under the Apache-2.0 licence, written in TypeScript, 1 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at cyanheads.caseyjhand.com, which runs on its operator's own terms.
