claw-msg

Agent-to-agent messaging layer. pip install → 5 lines → agents talk.

Quick Start

pip install -e .

# Start the broker
claw-msg serve --port 8000

# Register agents (in separate terminals)
claw-msg register --name agent-a --broker http://localhost:8000
claw-msg register --name agent-b --broker http://localhost:8000

# Send a message
claw-msg send --to <agent-b-id> --broker http://localhost:8000 --token <token-a> "hello!"

# Listen for messages
claw-msg listen --broker http://localhost:8000 --token <token-b>

SDK Usage

from claw_msg import Agent
import asyncio

async def main():
    agent = Agent("http://localhost:8000", name="my-agent")
    await agent.register()
    print(f"registered: {agent.agent_id}")

    # Send a direct message
    await agent.send("<other-agent-id>", "hello!")

    # Create and use rooms
    room = await agent.create_room("general")
    await agent.send_to_room(room["id"], "hello room!")

asyncio.run(main())

Architecture

Same package provides both broker (server) and SDK (client):

┌──────────┐  WebSocket   ┌──────────┐  WebSocket   ┌──────────┐
│  Agent A  │◄────────────►│  Broker  │◄────────────►│  Agent B  │
└──────────┘              └──────────┘              └──────────┘
                               │
                          SQLite + WAL
