Agentry MCP Server

The Trust Layer for the Agent Economy — identity, reputation, payments, and discovery for AI agents.

Overview

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.

No authentication required for read endpoints.
