A2A Debugger

The ultimate A2A (Agent-to-Agent) troubleshooting and debugging tool

A powerful command-line utility for debugging, monitoring, and inspecting A2A servers. Connect to A2A servers, list tasks, view conversation histories, and inspect task statuses with ease.

⚠️ Warning

This project is in its early stages of development.

Breaking changes are expected as we actively develop and refine the tool. Use with caution in production environments and be prepared for API changes, configuration format updates, and command-line interface modifications between versions.

We recommend pinning to specific versions in your scripts and monitoring the CHANGELOG.md for breaking changes.

🚀 Features
