A2A Go

A Go implementation of the Agent2Agent (A2A) protocol, enabling seamless communication between different agent frameworks.

Caution

This is an early development effort, do not use in production

Installation

go get github.com/co-browser/a2a-go

Quickstart

First, we'll start one of the google A2A agents:

cd A2A/samples/python/agents
uv run google_adk/.
INFO:     Started server process [4070]
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://localhost:10002 (Press CTRL+C to quit)

then we'll connect to it with a2a-go:

go run cmd/cli/main.go -agent=http://localhost:10002
