Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

describe
describe_agent
Fleet-standard self-description.
discover
discover_agents
Find ACTIVE agents matching ALL requested capabilities (AND semantics), deterministically ordered by match count then reputation.
register
register_agent
Register (or idempotently update) an agent identity. Returns a deterministic content-addressed DID. capabilities is a non-empty list of lowercase capability tags other agents can discover you by.
registrations
list_registrations
List registrations, optionally filtered by status (ACTIVE|REVOKED).
resolve
resolve_agent
Resolve an identity by agent_id or DID to its full public registration.
revoke
revoke_agent

Agent Identity Registry — questions

Answers built from our own checks of this server.

What can Agent Identity Registry do?
It exposes 6 tools, read directly from the server on our last check. Among them: describe_agent, discover_agents, list_registrations, register_agent, resolve_agent, revoke_agent. 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 Identity Registry working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 352 ms. The bar chart above shows every period we have measured.
How do I connect Agent Identity Registry?
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 Identity Registry need an API key?
No. Agent Identity Registry completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Agent Identity Registry?
It answers our handshake in 352 ms on average, which is faster than 40% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Agent Identity Registry open source?
Yes — written in Python, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
