Connect Agent Identity Registry and your agent gets 6 tools, among them describe_agent, discover_agents, list_registrations. It answers at https://mcp.viridisconservation.com/identity/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 22 October 2026, succeeded.
Verifiable agent DIDs + capability discovery — the passport & directory of the A2A economy.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
describe_agent | Fleet-standard self-description. |
discover_agents | Find ACTIVE agents matching ALL requested capabilities (AND semantics), deterministically ordered by match count then reputation. Inputs: capabilities, limit |
list_registrations | List registrations, optionally filtered by status (ACTIVE|REVOKED). Inputs: status |
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. Inputs: agent_id, capabilities, name, endpoint, pubkey, pricing |
resolve_agent | Resolve an identity by agent_id or DID to its full public registration. Inputs: agent_id, did |
revoke_agent | Revoke an identity: it disappears from discovery (terminal) but its record is retained for auditability. Inputs: agent_id, did |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.viridisconservation.com/identity/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
