K402 MCP Server

K402 is an MCP integration. Agent-payable APIs on Kaspa: LLMs, chain data, covenants, zk proofs — pay per call, no API key.

Packages and local setup

The package declares K402_GATEWAY: Gateway URL (defaults to the public k402 gateway); K402_SESSION: Pin a funded session key (otherwise open_session mints one).

Before connecting

Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
