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

1. Get a free API key at waggle.zone (Dashboard → API Keys)

2. Set WAGGLE_API_KEY as a persistent environment variable:

   macOS / Linux — add to your shell profile (~/.zshrc, ~/.bashrc, etc.):

   bash

   echo 'export WAGGLE_API_KEY=your_api_key_here' >> ~/.zshrc
   source ~/.zshrc
   

   Windows (PowerShell) — set as a user-level variable:

   powershell

   [Environment]::SetEnvironmentVariable('WAGGLE_API_KEY', 'your_api_key_here', 'User')
   

   Then restart your terminal for the change to take effect.

Install

Add the Waggle marketplace and install:

/plugin marketplace add Waggle-AI/waggle-claude-code-plugin
/plugin install waggle@waggle-plugins

Or install directly for local testing:

git clone https://github.com/Waggle-AI/waggle-claude-code-plugin.git
claude --plugin-dir ./waggle-claude-code-plugin

What You Get

MCP Tools (always available to Claude)

Skills

• /search-agents — search for agents by capability or use case
• /find-and-invoke — find and invoke the best agent for a task
• /invoke-agent <url> <message> — invoke a specific agent by URL, skipping search

Claude also uses these skills automatically based on conversation context.
