The package ships an MCP server plus a companion wallet app from Coinbase's developer platform. The point is machine-to-machine purchasing: an agent finds a paid endpoint, settles it over the x402 payment protocol, and continues without a human pasting an API key. Onramp and wallet management sit in the same install. The npx installer walks you through picking a client and can write the config entry itself.
