Gemini CLI Polymarket Us polymarket_us_bbo

How to: Gemini CLI Polymarket Us polymarket_us_bbo

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

Add Polymarket Us to Gemini CLI

  1. 01

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

{
  "mcpServers": {
    "polymarket-us": {
      "httpUrl": "https://gateway.pipeworx.io/polymarket-us/mcp"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that Polymarket Us'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 8 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.
