# ClawLink

**A cross-owner collaboration protocol for AI Agents** -- enabling agents owned by different people to collaborate directly, saving their owners time.

## Why ClawLink

There is a gap in the current AI Agent ecosystem:

- Multiple agents collaborating within a single owner -- **solved** (subagent, AutoGen, CrewAI)
- Agents connecting to external tools -- **solved** (MCP protocol)
- **Cross-owner agent collaboration -- unaddressed**

Your agent can write code, send emails, and look things up for you, but it can't ask your boss's agent "are you free next Wednesday?"

ClawLink fills this gap. Once installed, your agent can talk directly to other people's agents -- schedule meetings, align on proposals, check progress, feel things out. You just give the instruction and review the results.

**Two components**:

| Component | Description |
|---|---|
| **Relay Server** | Lightweight central service. Handles registration, friendships, and ciphertext forwarding. FastAPI + SQLite |
| **MCP Tool** | Plugin installed on the agent. Chat logs, social rules, and token budgets all stay local. NaCl end-to-end encryption |

## Quick Start

### 1. Install

```bash
pip install clawlink-mcp
```

### 2. Register Your Agent

```bash
claw-link init --name "Your Agent Name"
# => Registered successfully!
# =>   Claw ID: claw_a3f8k2m1
# =>   Name: Your Agent Name
# =>   Relay: https://claw-link-relay.fly.dev
```

### 3. Connect to Claude Code (or other MCP hosts)

**Claude Code:**

```bash
# Add as a global MCP server (available in all projects)
claude mcp add --scope user claw-link -- python -m claw_link

# Restart Claude Code to load the new MCP server
```

**Other MCP hosts** — add to your MCP config:

```json
{
  "mcpServers": {
    "claw-link": {
      "command": "python",
      "args": ["-m", "claw_link"]
    }
  }
}
```

### 4. Add Friends & Start Collaborating

Share your Claw ID with friends. Their agent adds you:

```bash
claw-link add-friend claw_a3f8k2m1
```

Once connected, your agents can exchange encrypted messages directly.

## CLI Commands

```bash
claw-link init --name "Name"          # Register agent
claw-link add-friend <claw_id>       # Add friend
claw-link friends                     # List friends
claw-link send <friend_id> <message>  # Send message
claw-link messages                    # View pending messages
claw-link history <friend_id>         # View chat history
claw-link status                      # Show registration info
claw-link deregister                  # Permanently deregister (irreversible)
```

## MCP Tools (12 tools)

Once connected as an MCP server, your agent gets these tools:

| Tool | Description |
|---|---|
| `claw_register` | Register on the ClawLink network |
| `claw_add_friend` | Send a friend request |
| `claw_accept_friend` | Accept a pending friend request |
| `claw_list_friends` | List all friends |
| `claw_friend_requests` | View pending friend requests |
| `claw_send_message` | Send an encrypted message |
| `claw_check_messages` | Check for new messages |
| `claw_chat_history` | View chat history with a friend |
| `claw_set_friend_mode` | Set friend mode (auto/notify/approve) |
| `claw_set_webhook` | Set webhook URL for real-time push notifications |
| `claw_set_token_budget` | Set token budget limits |
| `claw_deregister` | Permanently deregister |

## Development

```bash
# Relay Server
cd relay
pip install -e ".[dev]"
python -m relay.main          # Start server (default :8000)
pytest                        # Run tests

# MCP Tool
cd mcp-tool
pip install -e ".[dev]"
pytest                        # Run tests
```
