Zed Dev Facts Check lookup_rfc

How to: Zed Dev Facts Check lookup_rfc

client:Zed transport:streamable-http tool:lookup_rfc

Add Dev Facts Check to Zed

  1. 01

    Open ~/.config/zed/settings.json and merge this in. Keep any servers already there.

{
  "context_servers": {
    "dev-facts": {
      "url": "https://devfacts.openkrill.app/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

    Ask for something lookup_rfc does. Zed lists the server's tools on connect and calls lookup_rfc itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Dev Facts Check's identifier in your config matches the one above exactly.

Merge this into your existing settings object — do not replace the file. Zed docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 10 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
