How to: Zed Medical Terminologies MCP terminology_diff

client:Zed transport:streamable-http tool:terminology_diff

Add Medical Terminologies MCP to Zed

  1. 01

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

{
  "context_servers": {
    "medical-terminologies-mcp": {
      "url": "https://medical.sidneybissoli.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Medical Terminologies MCP's identifier in your config matches the one above exactly.

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

Set these first

Medical Terminologies MCP will not start until these are set, so terminology_diff never becomes available.

  • WHO_CLIENT_SECRET
  • WHO_ICD11_RELEASE_ID

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 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.
