Gemini CLI Halves halves_create_group_link

How to: Gemini CLI Halves halves_create_group_link

client:Gemini CLI transport:streamable-http tool:halves_create_group_link

Add Halves to Gemini CLI

01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "halves": {
      "httpUrl": "https://halves.clawhard.com/mcp"
    }
  }
}

02
Save the file and restart Gemini CLI.
03
Ask for something halves_create_group_link does. Gemini CLI lists the server's tools on connect and calls halves_create_group_link itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that Halves's identifier in your config matches the one above exactly.

Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 November 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.
