### 🤖 Cursor Assistant

I see the issue! This is a Pydantic version compatibility problem. The `pydantic-settings` package requires a specific version of Pydantic, and there's a mismatch. Let me fix the requirements.txt file with proper version constraints:

---

### 🤖 Cursor Assistant

Now, let's reinstall the dependencies with the correct versions:

---

### 🤖 Cursor Assistant

Good! The Pydantic versions have been upgraded. Now let's test if the server starts:

---

### 🤖 Cursor Assistant

There's a typing import issue. In Python 3.11, we can use lowercase `list` instead of `List`. Let me fix this:

---

### 🤖 Cursor Assistant

Good, let me check and fix browser_tools.py as well:

---

### 🤖 Cursor Assistant

The `on_shutdown` decorator doesn't exist in FastMCP. Let me fix the cleanup approach:

---

### 🤖 Cursor Assistant

There's an `anyio` version conflict. Let me upgrade it:

---

### 🤖 Cursor Assistant

Perfect! Now let's test if the server starts properly:

---

### 🤖 Cursor Assistant

Excellent! The server is starting successfully now. Let me update the requirements.txt with the correct dependency versions:

---

### 🤖 Cursor Assistant

Perfect! The server is now working correctly. Let me create a summary of what was fixed:

## ✅ Issues Fixed

### 1. **Pydantic Version Incompatibility**
**Problem:** `ModuleNotFoundError: No module named 'pydantic._internal._signature'`

**Solution:** Updated Pydantic to version 2.8.0+ and added `pydantic-settings>=2.4.0`

### 2. **anyio Version Incompatibility**  
**Problem:** `TypeError: 'function' object is not subscriptable`

**Solution:** Upgraded anyio from 3.7.1 to 4.5.0+

### 3. **Missing Type Import**
**Problem:** `NameError: name 'List' is not defined`

**Solution:** Added `List` to typing imports in `hitl_tools.py`

### 4. **Invalid Decorator**
**Problem:** `AttributeError: 'FastMCP' object has no attribute 'on_shutdown'`

**Solution:** Replaced decorator with try/finally cleanup pattern

## 📋 Updated Files

1. **requirements.txt** - Added version constraints for compatibility
2. **src/main.py** - Fixed lifecycle management
3. **src/hitl_tools.py** - Added List import
4. **INSTALL.md** - Created comprehensive installation guide

## ✅ Server Status

The MCP server is now **running successfully**! You can verify with:

```bash
cd /Users/boj/ai-agent-book/projects/week4/collaboration-tools

# The server should start without errors (it waits for stdin input)
python src/main.py
```

## 🚀 Next Steps

1. **Configure your environment:**
   ```bash
   cp env.example .env
   nano .env  # Add your API keys
   ```

2. **Run the demo:**
   ```bash
   python quickstart.py
   ```

3. **Or try the real-world example:**
   ```bash
   python client_example.py
   ```

4. **Use with Claude Desktop** by adding to your `claude_desktop_config.json`:
   ```json
   {
     "mcpServers": {
       "collaboration-tools": {
         "command": "python",
         "args": ["/Users/boj/ai-agent-book/projects/week4/collaboration-tools/src/main.py"]
       }
     }
   }
   ```

The server is now ready to use with all 19 collaboration tools! 🎉
