      "command": "node",
      "args": ["D:\\Lupo\\Source\\AI\\CladueCOO\\mcp-coordination-system\\mcp-proxy-client.js"],
      "env": {
        "SSE_SERVER_URL": "http://localhost:3444/mcp",
        "USE_HTTP": "true"
      }
    }
  }
}
```

### **Claude Code Integration**
```json
{
  "mcp": {
    "servers": {
      "coordination-system-proxy": {
        "command": "node", 
        "args": ["mcp-proxy-client.js"],
        "cwd": "D:\\Lupo\\Source\\AI\\CladueCOO\\mcp-coordination-system",
        "env": {

### **Project Management** 
- `get_projects()`, `get_project()`, `create_project()`, `update_project()`

### **Task Management**
- `get_tasks()`, `get_task()`, `create_task()`, `claim_task()`, `update_task()`, `get_pending_tasks()`

### **Communication**
- `send_message()`, `get_messages()`

### **Instance Management**
- `register_instance()`, `update_heartbeat()`, `get_instances()`

### **Lessons System**
- `submit_lessons()`, `get_lessons()`, `get_onboarding_lessons()`, `get_lesson_patterns()`, `export_lessons()`

## ✅ SUCCESS CRITERIA MET
