agent_card_check
shallowco.fingersai/fingers · Verify this server
VERIFY ANOTHER AI AGENT before trusting or paying it. Fetches its A2A Agent Card (+ ERC-8004 on-chain identity proof) and checks the claims -- A2A does NOT verify card authenticity, so impersonation, card tampering, and tool-squatting are real. Reports what the agent claims (name, skills, endpoints, payment address, on-chain registration) and flags problems: unreachable card, brand-new domain, a payment wallet flagged for scam/drain, or a card/registration mismatch. The KYA-complement (they say the agent is authorized; fingers says it's who it claims + safe). Give the agent's domain or Agent Card URL.
