vbcherepanov/a2abridge

a2abridge is a small Go-based bridge that turns local AI coding agents into A2A 1.0 peers so they can discover each other, share inboxes and delegate tasks without copy‑pasting. It’s for developers or teams running multiple agents on the same machine or across machines (IDE CLIs, terminal agents, worker processes) who need cross‑vendor interoperability and no vendor lock‑in. Key features: - Wraps each agent as an A2A 1.0 peer (JSON‑RPC 2.0 + SSE), implements task APIs (SendMessage, GetTask, ListTasks, SubscribeToTask, etc.). - Local directory discovery, optional cross‑machine mTLS (ed25519) for zero‑trust links. - MCP tools and IDE integration (a2a_whoami, a2a_send_message, inbox, worker mode). - One‑line installer, single ~10MB binary, cross‑platform (macOS/Linux/Windows/WSL2). - Open‑protocol focus so any A2A‑compliant agent (ADK, LangGraph, CrewAI, etc.) can join.
