What It Does
Provides a terminal client implementing an Agent-to-Agent Protocol (A2A) for interacting with local or remote agent servers. Uses a CLI/TUI to send and receive A2A messages and can connect to MCP-compatible servers and local runtimes like ollama or litellm Open Agent Specification. Designed as a lightweight developer tool for exploring A2A flows from the command line and scripting agent interactions.
Key Benefits
As agents begin to communicate directly, simple, observable clients are essential for debugging and measuring interaction quality. A terminal A2A client makes it easy to capture message traces, reproduce failure modes, and collect evidence about agent behavior Mutual Verification Pattern. That visibility is a practical first step toward building agent-to-agent evaluation and tracking agent track records in production LLM-as-Judge Pattern.
When to Use
Developers and researchers testing A2A flows, reproducing agent interactions, and collecting message-level traces from the terminal.
Use Cases
- Replay and inspect agent-to-agent message exchanges from the terminal to diagnose failures
- Script and automate small A2A experiments against local runtimes like ollama or litellm
- Capture interaction logs as input for reputation or evaluation tooling
- Validate MCP/A2A protocol conformance during development
