From the README

# A2A Protocol Inspector

The A2A Inspector is a web-based tool designed to help developers inspect, debug, and validate servers that implement the A2A (Agent2Agent) protocol. It provides a user-friendly interface to interact with an A2A agent, view communication, and ensure specification compliance.

The application is built with a FastAPI backend and a TypeScript frontend.

## Features

- **Connect to a local A2A Agent:** Specify the base URL of any agent server to connect (e.g., `http://localhost:5555`).
- **View Agent Card:** Automatically fetches and displays the agent's card.
- **Spec Compliance Checks:** Performs basic validation on the agent card to ensure it adheres to the A2A specification.
- **Live Chat:** A chat interface to send and receive messages with the connected agent.
- **Debug Console:** A slide-out console shows the raw JSON-RPC 2.0 messages sent and received between the inspector and the agent server.

## Prerequisites

- Python 3.10+
