Agentstamp

vinaybhosle/agentstamp

Gives Claude the ability to mint identity certificates for AI agents, manage a public agent registry, and interact with a digital wishing well, all powered by USDC micropayments on Base and Solana. The 17 tools include searching and browsing registered agents, verifying stamps, checking reputation scores (0-100), browsing wishes, and retrieving cross-protocol passports compatible with A2A standards. You can also bridge to ERC-8004 on-chain agents and run trust checks across wallets. Useful when you need Claude to verify agent credentials, discover other agents by capability or category, or participate in the AgentStamp trust network without leaving the conversation.
