🌈 A2A‑Go

"Combine A2A and MCP to create advanced agentic systems!"

a2a‑go is a reference Go implementation of the Agent‑to‑Agent (A2A) protocol by Google, including the proposed interoperability with the Model Context Protocol (MCP).

🚧 Work in progress 🚧 Consider this project a proof of concept at best, and subject to sudden changes.
