# OpenClaw A2A Gateway

A production-ready plugin for OpenClaw that implements the A2A (Agent-to-Agent) v0.3.0 protocol, enabling bidirectional communication, task delegation, and automatic peer discovery between OpenClaw agents and other A2A-compatible agents across different servers.

## Overview

**OpenClaw A2A Gateway** is a lightweight, production-ready plugin for [OpenClaw](https://github.com/openclaw/openclaw) — the popular open-source personal AI assistant framework. It implements the **A2A (Agent-to-Agent) v0.3.0 protocol** (originally from Google, now under the Linux Foundation), turning any OpenClaw agent into a fully interoperable node in the growing A2A ecosystem.

With zero-config installation and automatic peer discovery, agents can discover each other's capabilities via **Agent Cards**, delegate tasks, exchange results, and collaborate across servers using standardized JSON-RPC 2.0 over HTTP(S).

## Key Features

- **Full A2A Protocol Compliance** (v0.3.0): Agent Card publishing, task creation, status tracking, cancellation, and result streaming
- **Bidirectional Communication**: OpenClaw agents can act as both A2A servers (exposing skills) and clients (delegating to other agents)
- **Automatic Peer Discovery**: Finds and connects to other A2A agents on the network with minimal setup
- **JSON-RPC + REST Endpoint**: Exposes a standards-compliant interface for external agents
- **Secure & Scoped**: Supports authentication, permissions, and trust registries (with community extensions)
- **Zero-Config Install**: Simple npm/git clone deployment inside OpenClaw's plugin system
- **Multi-Language Support**: Works with OpenClaw's multi-model backend (Anthropic, OpenAI, local LLMs)

## Installation

```bash
# Navigate to OpenClaw plugins directory
mkdir -p ~/.openclaw/workspace/plugins
cd ~/.openclaw/workspace/plugins

git clone https://github.com/win4r/openclaw-a2a-gateway.git a2a-gateway
cd a2a-gateway
npm install --production
```

Restart your OpenClaw instance. The gateway automatically starts and registers an A2A endpoint.

## Use Cases

- **Multi-Agent Orchestration**: Split complex tasks across specialized OpenClaw agents (researcher → writer → reviewer)
- **Cross-Platform Collaboration**: OpenClaw agents working with agents from other frameworks supporting A2A
- **Task Delegation**: Hand off subtasks like calendar management, email handling, or web research to specialized agents
- **Enterprise & Team Workflows**: Secure agent-to-agent communication in company environments
- **Self-Improving Systems**: Agents that learn from each other and share knowledge via A2A
- **Hybrid Ecosystems**: Combining OpenClaw with MCP tools, other A2A agents, and human interfaces (A2H)
