Gemini CLI Formosa MCP — Taiwan data invoice_check

How to: Gemini CLI Formosa MCP — Taiwan data invoice_check

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

Add Formosa MCP — Taiwan data to Gemini CLI

  1. 01

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

{
  "mcpServers": {
    "formosa-mcp": {
      "httpUrl": "https://formosa-mcp.ycsmiley.workers.dev/mcp"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Formosa MCP — Taiwan data'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

Formosa MCP — Taiwan data will not start until these are set, so invoice_check never becomes available.

  • TDX_CLIENT_ID
  • TDX_CLIENT_SECRET

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.
