What is the Cyanheads MCP server?

Most cloud and infrastructure work still happens through a UI a human drives. Cyanheads MCP server moves it into the conversation instead. Fleet discovery for the cyanheads MCP ecosystem — semantic search + install snippets.

The short version

  • Declarative tool definitions — single file per tool, framework handles registration and validation
  • Unified error handling with typed error contracts and recovery hints
  • Pluggable auth (none, jwt, oauth)
  • Structured logging with optional OpenTelemetry tracing
  • Runs locally (stdio/HTTP) or on Cloudflare Workers from the same codebase
  • Hourly background catalog refresh with atomic swap on generatedAt change — no restart needed when the fleet updates

The tools it exposes

The server publishes 4 tools. What each one is for:

  • cyanheads_search_catalog — Search fleet tools and servers by natural-language query. Returns ranked matches with brief summaries and the owning server
  • cyanheads_describe_entry — Return the connection URL and per-client install snippets for a named tool or server
  • Prerequisites — The Prerequisites tool exposed by this server
  • Installation — The Installation tool exposed by this server

Getting it running

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

What it needs from you

Configuration is passed through the environment: MCP_TRANSPORT_TYPE, MCP_LOG_LEVEL, MCP_HTTP_HOST, MCP_HTTP_ENDPOINT_PATH, CATALOG_URL, EMBEDDING_MODEL_ID. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

How it compares

This sits in the cloud and infrastructure group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Cyanheads's toolset — cyanheads_search_catalog, cyanheads_describe_entry, Prerequisites and 1 more — is a fair guide to whether it matches your workflow. It is maintained by cyanheads; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Cyanheads to MCP-compatible AI assistants such as Claude and Cursor, exposing 4 tools (cyanheads_search_catalog, cyanheads_describe_entry, Prerequisites, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Cyanheads directly.
