Discover, search, invoke, and rate A2A (Agent-to-Agent) protocol agents.

This server provides a catalog-style interface for locating and interacting with AI agents that implement Google's A2A protocol. It exposes tooling to search, invoke, and rate agents within the Waggle ecosystem, enabling cross-agent collaboration and discovery.

🛠️ Key Features

Discover and index A2A protocol agents
Search, connect, and invoke agents from a unified interface
Agent rating and feedback mechanisms
Readme-derived context and setup guidance for agents

🚀 Use Cases

Locating compatible A2A agents for workflow automation
Invoking agents to perform tasks within Agent-to-Agent ecosystems
Evaluating agent capabilities through ratings and descriptions

⚡ Developer Benefits

Clear exposure of A2A-compatible agents via a single catalog
Easy integration with Waggle index and authoring workflow
Reference readme excerpts to understand setup and usage

⚠️ Limitations

Data sample shows partial readme content; completeness may vary
Indexing scope depends on available agent implementations and metadata
Readme excerpts may require external links for full setup instructions

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_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:

code

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

Or install directly for local testing:

bash

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)

Tool	Description
`search`	Semantic search for A2A agents by capability
`info`	Get detailed info on a specific agent
`invoke`	Send a task to an agent and get results
`poll`	Check status of async agent tasks
`register`	Submit a new agent URL for indexing
`check_usage`	View your API quota and usage
`rate_transaction`	Rate an agent interaction (doesn't consume API quota)

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
/register-agent — register a new A2A agent for indexing

Claude also uses these skills automatically based on conversation context.
