Bridge for Agent-to-Agent communication across different protocols. Agent 间通信桥接工具，支持多种协议。

A unified communication bridge that allows Agents using different protocols (MCP, A2A, HTTP, WebSocket) to communicate with each other.

一个统一的通信桥接工具，允许使用不同协议（MCP、A2A、HTTP、WebSocket）的 Agent 相互通信。

Quick Start | 快速开始

# Install globally
npm install -g agent-bridge

# Start bridge server
agent-bridge start

# Or use as library
const { Bridge } = require('agent-bridge');
const bridge = new Bridge();

Usage Examples | 使用示例

Basic Bridge Usage

const { Bridge } = require('agent-bridge');

const bridge = new Bridge();

// Register adapters
bridge.registerAdapter('mcp', new McpAdapter());
bridge.registerAdapter('a2a', new A2aAdapter());

// Send message
await bridge.send({
  to: 'mcp:server1',
  content: 'Hello from MCP agent'
});

CLI Usage

# Start bridge with config
agent-bridge start --config bridge.yaml

# Send test message
agent-bridge send --to "a2a:agent1" --message "Hello"

# List supported protocols
agent-bridge protocols
