A2A Registry

概要

The A2A Registry is a Model Context Protocol (MCP) server designed to manage a centralized registry for agents that implement the Agent-to-Agent (A2A) protocol. It offers dual API access, enabling agent registration, querying, and management via both a standard REST API and MCP tools. With intelligent agent registration, it automatically fetches AgentCards from URLs using smart routing and supports multiple storage backends like JSON files or SQLite databases, ensuring flexible and concurrent access for various clients.
