Gemini CLI x402 mcp Prompt/x402.buy_paid_api

How to: Gemini CLI x402 mcp x402.buy_paid_api

client:Gemini CLI transport:streamable-http prompt:x402.buy_paid_api

Add x402 mcp to Gemini CLI

  1. 01

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

{
  "mcpServers": {
    "x402-mcp": {
      "httpUrl": "https://x402-mcp.onrender.com/mcp/mcp"
    }
  }
}
  1. 02

    Save the file and restart Gemini CLI.

  2. 03

    x402.buy_paid_api is surfaced in the client's prompt or command menu. Unlike a tool, you invoke it deliberately — Gemini CLI will not call it for you.

  3. 04

    If it does not appear, check that x402 mcp is connected and that you are looking at its prompts rather than its tools.

Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs

Same prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 24 September 2026. A listing does not declare its prompts, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each prompt's arguments.
