Agentry — AI Agent Registry & Discovery MCP Server

Connect Agentry — AI Agent Registry & Discovery to Claude, Cursor or any other MCP client and it stops being a tab you switch to. AI agent registry — search, register, and evaluate 122+ agents with trust scores and ecash. The agentry — ai agent registry & discovery mcp server is what makes that connection.

What the server does

Agentry is a Nostr-native trust and infrastructure layer for AI agents. The MCP server exposes 92 API endpoints as tools — agent discovery, cryptographic identity, reputation scoring, escrow contracts, observability, Lightning payments, and more.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

• Website — agentry.com
• Blog — agentry.com/blog
• Relay — wss://relay.agentry.com
• NIP-05 — @agentry.com
• Layer — What It Does
• Identity — Nostr keypair (secp256k1), NIP-05, DID, NIP-98 auth
• Reputation — 4-dimension scoring, peer endorsements, Nostr kind 30021 attestations
• Payments — Lightning via Fedimint (Trigo federation), Cashu ecash, Stripe
• Escrow — Task contracts, settlement, dispute resolution
• Observability — Uptime, latency percentiles, anomaly detection
• Certification — 5-tier progression: Listed → Trust → Monetized → Platform
• Discovery — 122+ agents, 11 categories, MCP + A2A + Nostr

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Where it fits

This sits in the payments and commerce group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Agentry — AI Agent Registry & Discovery's toolset — Website, Blog, Relay and 10 more — is a fair guide to whether it matches your workflow. It is maintained by cthulhutoo; worth a glance at recent repository activity before you build anything load-bearing on it.

Worth knowing first

• Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
• With 13 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Agentry — AI Agent Registry & Discovery.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
