Overview

OpenClaw A2A Gateway is a lightweight, production-ready plugin for 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

# 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)
