This connects Claude to Waggle's A2A agent directory, letting you search for, invoke, and rate agents that implement Google's Agent-to-Agent protocol. You get MCP tools for semantic search across indexed agents, direct invocation with async polling support, and registration of new agents. The free tier gives you 100 requests per day and 10 per minute. Useful when you need to discover specialized agents for tasks like weather data, currency conversion, or geospatial analysis instead of building functionality from scratch. Requires a free API key from waggle.zone and runs over streamable HTTP transport.
