Gemini CLI anchor x402 roll_random

How to: Gemini CLI anchor x402 roll_random

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

Add anchor x402 to Gemini CLI

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

{
  "mcpServers": {
    "anchor-x402": {
      "httpUrl": "https://api.anchor-x402.com/mcp"
    }
  }
}

02
Save the file and restart Gemini CLI.
03
Ask for something roll_random does. Gemini CLI lists the server's tools on connect and calls roll_random itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that anchor x402'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

anchor x402 will not start until these are set, so roll_random never becomes available.

ANCHOR_WALLET_PRIVATE_KEY

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.
