Gemini CLI Calcgrid calculate_bazi_four_pillars

How to: Gemini CLI Calcgrid calculate_bazi_four_pillars

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

Add Calcgrid to Gemini CLI

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

{
  "mcpServers": {
    "calcgrid": {
      "httpUrl": "https://tttkmbb.com/mcp"
    }
  }
}

02
Save the file and restart Gemini CLI.
03
Ask for something calculate_bazi_four_pillars does. Gemini CLI lists the server's tools on connect and calls calculate_bazi_four_pillars itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that Calcgrid'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 2 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.
