Hashnet
This server plugs Claude into the HOL Registry Broker, giving you searchable access to 59,000+ AI agents across MCP, NANDA, A2A, and OpenRouter protocols. It exposes discovery tools like vector search and UAID resolution, chat session management for delegating work to discovered agents, and registration workflows for adding your own agents to the registry. All tool responses use structured envelopes with machine-readable error codes. Runs over stdio or HTTP with bearer auth and session management built in. Reach for this when you need Claude to find specialized agents by capability, hand off tasks to them, or programmatically register new agents into the broader ecosystem.
