verify

verify_agent_identity

Confirms an AI agent/service is who it claims to be. Fuses cross-signal domain verification (WHOIS/CT/Wayback/DNS) with a real .well-known/agent-card.json fetch and a real MCP `initialize` handshake against agent_endpoint_url (if given), and checks that the agent card's own declared url is bound to `domain`. Returns VERIFIED_LIVE_AGENT, AGENT_DOMAIN_MISMATCH, LIKELY_HALLUCINATED_AGENT, DOMAIN_VERIFIED_AGENT_UNREACHABLE, VERIFIED_LIVE_DOMAIN_ONLY (no agent_endpoint_url given), or UNVERIFIED_AGENT.

Agent Verification API — questions

Answers built from our own checks of this server.

What can Agent Verification API do?

It exposes 1 tools, read directly from the server on our last check. Among them: verify_agent_identity. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Agent Verification API working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 197 ms. The bar chart above shows every period we have measured.

The registry lists Agent Verification API as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Agent Verification API?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Agent Verification API need an API key?

No. Agent Verification API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

Is Agent Verification API open source?

We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
