Gemini CLI Nonlinear Calendar personal_day

How to: Gemini CLI Nonlinear Calendar personal_day

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

Add Nonlinear Calendar to Gemini CLI

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

{
  "mcpServers": {
    "balance-engine": {
      "httpUrl": "https://balance-engine.vercel.app/api/mcp"
    }
  }
}

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

Set these first

Nonlinear Calendar will not start until these are set, so personal_day never becomes available.

BALANCE_ENGINE_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.
