YieldAgentX402 MCP server

YieldAgentX402 is a helper that lets your AI work with crypto wallets and payments without ever holding your private keys. It is made for teams and people who want an AI assistant to look up balances, preview transfers, and settle payments on many blockchains. If you use ChatGPT or Claude and want it to help with crypto tasks in a safe, checked way, this is for you.

What this MCP server does

You ask your AI something like what is my balance or can I send this payment. Your AI passes the request to this helper, which talks to the YieldAgentX402 service. The service checks your rules, runs the action, and returns a signed receipt as proof. You get the result back in your chat, plus a record you can verify later.
