Agentstamp MCP Server

Stamp your agent into existence. A lightweight x402-powered platform combining AI agent identity certification, a public agent registry, reputation scores, cross-protocol passports, and a digital wishing well - all payable via USDC micropayments on Base and Solana. It is available as a remote MCP endpoint.

Teams that work with agent identity, ed25519 and erc 8004 and want a hosted endpoint instead of running a local process. The project is written in JavaScript.
