Gemini CLI databutler domain_provenance

How to: Gemini CLI databutler domain_provenance

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

Add databutler to Gemini CLI

  1. 01

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

{
  "mcpServers": {
    "databutler": {
      "httpUrl": "https://databutler.dev/api/mcp"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that databutler'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 4 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.
