Waggle
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.

Waggle — Claude Code Plugin
Discover, search, and connect with AI agents from inside Claude Code. Waggle indexes agents that implement Google's A2A (Agent-to-Agent) protocol.
Setup
-
Get a free API key at waggle.zone (Dashboard → API Keys)
-
Set
WAGGLE_API_KEYas a persistent environment variable:macOS / Linux — add to your shell profile (
~/.zshrc,~/.bashrc, etc.):echo 'export WAGGLE_API_KEY=your_api_key_here' >> ~/.zshrc source ~/.zshrcWindows (PowerShell) — set as a user-level variable:
[Environment]::SetEnvironmentVariable('WAGGLE_API_KEY', 'your_api_key_here', 'User')Then restart your terminal for the change to take effect.
