Zed Hermoso call_tool

How to: Zed Hermoso call_tool

client:Zed transport:streamable-http tool:call_tool

Add Hermoso to Zed

  1. 01

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

{
  "context_servers": {
    "hermoso": {
      "url": "https://app.hermoso.ai/mcp?src=registry"
    }
  }
}
  1. 02

    Save the file and restart Zed.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Hermoso'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

Hermoso will not start until these are set, so call_tool never becomes available.

  • HERMOSO_TOKEN
  • HERMOSO_API_BASE

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.
