# Basecamp MCP Integration

This project provides a **FastMCP-powered** integration for Basecamp 3, allowing Cursor to interact with Basecamp directly through the MCP protocol.

✅ **Migration Complete:** Successfully migrated to official Anthropic FastMCP framework with **100% feature parity** (all 46 tools)
🚀 **Ready for Production:** Full protocol compliance with MCP 2025-06-18

## Configuration

The Basecamp MCP server is configured entirely via environment variables. No `.env` file is required.

### Required Environment Variables

All required configuration is passed via environment variables:

- `BASECAMP_CLIENT_ID` - OAuth client ID from 37signals
- `BASECAMP_CLIENT_SECRET` - OAuth client secret from 37signals
- `BASECAMP_ACCOUNT_ID` - Your Basecamp account ID
- `BASECAMP_REDIRECT_URI` - OAuth callback URL (usually `http://localhost:8000/auth/callback`)
- `USER_AGENT` - User agent string for API requests

### Data Locations

The server stores data in XDG-compliant locations:

| File Type | Default Location | Environment Variable Override |
|-----------|------------------|-------------------------------|
| OAuth Tokens | `~/.local/share/basecamp-mcp/oauth_tokens.json` | `BASECAMP_TOKEN_FILE` |
| Server Logs | `~/.local/state/basecamp-mcp/` | `BASECAMP_LOG_DIR` |

### Optional .env File (Development Only)

For local development, you can optionally create a `.env` file to avoid setting environment variables each time:

```bash
# Default location: ~/.config/basecamp-mcp/.env
# Or override with: BASECAMP_ENV_FILE=/custom/path/.env
BASECAMP_CLIENT_ID=your_client_id_here
BASECAMP_CLIENT_SECRET=your_client_secret_here
BASECAMP_ACCOUNT_ID=your_account_id_here
BASECAMP_REDIRECT_URI=http://localhost:8000/auth/callback
USER_AGENT="Your App Name (your@email.com)"
```

**Note:** The server works perfectly without a `.env` file - it's only a convenience for development.

## Quick Setup

This server works with both **Cursor** and **Claude Desktop**. Choose your preferred client:

### Prerequisites

- **Python 3.10+** (required for MCP SDK) — or use `uv` which auto-downloads the correct version
- A Basecamp 3 account
- A Basecamp OAuth application (create one at <https://launchpad.37signals.com/integrations>)

## For Cursor Users

### One-Command Setup

1. **Clone and set up with uv (recommended):**

   ```bash
   git clone <repository-url>
   cd basecamp-mcp

   # Using uv (recommended - auto-downloads Python 3.12)
   uv venv --python 3.12 venv
   source venv/bin/activate  # or venv\Scripts\activate on Windows
   uv pip install -r requirements.txt
   uv pip install mcp
   ```

   **Alternative: Using pip** (requires Python 3.10+ already installed):

   ```bash
   python setup.py
   ```

   The setup automatically:
   - ✅ Creates virtual environment
   - ✅ Installs all dependencies (FastMCP SDK, etc.)
   - ✅ Creates `.env` template file
   - ✅ Tests MCP server functionality

2. **Configure OAuth credentials:**
   Edit the generated `.env` file:

   ```bash
   BASECAMP_CLIENT_ID=your_client_id_here
   BASECAMP_CLIENT_SECRET=your_client_secret_here
   BASECAMP_ACCOUNT_ID=your_account_id_here
   USER_AGENT="Your App Name (your@email.com)"
   ```

3. **Authenticate with Basecamp:**

   ```bash
   python oauth_app.py
   ```

   Visit <http://localhost:8000> and complete the OAuth flow.

4. **Generate Cursor configuration:**

   ```bash
   python generate_cursor_config.py
   ```

5. **Restart Cursor completely** (quit and reopen, not just reload)

6. **Verify in Cursor:**
   - Go to Cursor Settings → MCP
   - You should see "basecamp" with a **green checkmark**
   - Available tools: **46 tools** for complete Basecamp control

### Test Your Setup

```bash
# Quick test the FastMCP server (works with both clients)
echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}
{"jsonrpc":"2.0","method":"notifications/initialized","params":{}}
{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' | python basecamp_fastmcp.py

# Run automated tests  
python -m pytest tests/ -v
```

## For Claude Desktop Users

Based on the [official MCP quickstart guide](https://modelcontextprotocol.io/quickstart/server), Claude Desktop integration follows these steps:

### Setup Steps

1. **Complete the basic setup** (steps 1-3 from Cursor setup above):

   ```bash
   git clone <repository-url>
   cd basecamp-mcp
   python setup.py
   # Configure .env file with OAuth credentials
   python oauth_app.py
   ```

2. **Generate Claude Desktop configuration:**

   ```bash
   python generate_claude_desktop_config.py
   ```

3. **Restart Claude Desktop completely** (quit and reopen the application)

4. **Verify in Claude Desktop:**
   - Look for the "Search and tools" icon (🔍) in the chat interface
   - You should see "basecamp" listed with all 46 tools available
   - Toggle the tools on to enable Basecamp integration

### Claude Desktop Configuration

The configuration is automatically created at:

- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `~/AppData/Roaming/Claude/claude_desktop_config.json`  
- **Linux**: `~/.config/claude-desktop/claude_desktop_config.json`

Example configuration generated:

```json
{
  "mcpServers": {
    "basecamp": {
      "command": "/path/to/your/project/venv/bin/python",
      "args": ["/path/to/your/project/basecamp_fastmcp.py"],
      "env": {
        "PYTHONPATH": "/path/to/your/project",
        "VIRTUAL_ENV": "/path/to/your/project/venv",
        "BASECAMP_ACCOUNT_ID": "your_account_id"
      }
    }
  }
}
```

### Usage in Claude Desktop

Ask Claude things like:

- "What are my current Basecamp projects?"
- "Show me the latest campfire messages from the Technology project"
- "Create a new card in the Development column with title 'Fix login bug'"
- "Get all todo items from the Marketing project"
- "Search for messages containing 'deadline'"

### Troubleshooting Claude Desktop

**Check Claude Desktop logs** (following [official debugging guide](https://modelcontextprotocol.io/quickstart/server#troubleshooting)):

```bash
# macOS/Linux - Monitor logs in real-time
tail -n 20 -f ~/Library/Logs/Claude/mcp*.log

# Check for specific errors
ls ~/Library/Logs/Claude/mcp-server-basecamp.log
```

**Common issues:**

- **Tools not appearing**: Verify configuration file syntax and restart Claude Desktop
- **Connection failures**: Check that Python path and script path are absolute paths
- **Authentication errors**: Ensure OAuth flow completed successfully (`oauth_tokens.json` exists)

## Architecture

The project uses the **official Anthropic FastMCP framework** for maximum reliability and compatibility:

1. **FastMCP Server** (`basecamp_fastmcp.py`) - Official MCP SDK with 46 tools, compatible with both Cursor and Claude Desktop
2. **OAuth App** (`oauth_app.py`) - Handles OAuth 2.0 flow with Basecamp  
3. **Token Storage** (`token_storage.py`) - Securely stores OAuth tokens
4. **Basecamp Client** (`basecamp_client.py`) - Basecamp API client library
5. **Search Utilities** (`search_utils.py`) - Search across Basecamp resources
6. **Setup Automation** (`setup.py`) - One-command installation
7. **Configuration Generators**:
   - `generate_cursor_config.py` - For Cursor IDE integration
   - `generate_claude_desktop_config.py` - For Claude Desktop integration

## Troubleshooting

### Common Issues (Both Clients)

- 🔴 **Red/Yellow indicator:** Run `python setup.py` to create proper virtual environment
- 🔴 **"0 tools available":** Virtual environment missing MCP packages - run setup script
- 🔴 **"Tool not found" errors:** Restart your client (Cursor/Claude Desktop) completely
- ⚠️ **Missing BASECAMP_ACCOUNT_ID:** Add to `.env` file, then re-run the config generator

### Quick Fixes

**Problem: Server won't start**

```bash
# Test if FastMCP server works:
./venv/bin/python -c "import mcp; print('✅ MCP available')"
# If this fails, run: python setup.py
```

**Problem: Wrong Python version**

```bash
python --version  # Must be 3.10+
# If too old, use uv which auto-downloads the correct Python:
uv venv --python 3.12 venv && source venv/bin/activate && uv pip install -r requirements.txt && uv pip install mcp
```

**Problem: Authentication fails**

```bash  
# Check OAuth flow:
python oauth_app.py
# Visit http://localhost:8000 and complete login
```

### Manual Configuration (Last Resort)

**Cursor config location:** `~/.cursor/mcp.json` (macOS/Linux) or `%APPDATA%\Cursor\mcp.json` (Windows)  
**Claude Desktop config location:** `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS)

```json
{
    "mcpServers": {
        "basecamp": {
            "command": "/full/path/to/your/project/venv/bin/python",
            "args": ["/full/path/to/your/project/basecamp_fastmcp.py"],
            "cwd": "/full/path/to/your/project",
            "env": {
                "PYTHONPATH": "/full/path/to/your/project",
                "VIRTUAL_ENV": "/full/path/to/your/project/venv",
                "BASECAMP_ACCOUNT_ID": "your_account_id"
            }
        }
    }
}
```

## Finding Your Account ID

If you don't know your Basecamp account ID:

1. Log into Basecamp in your browser
2. Look at the URL - it will be like `https://3.basecamp.com/4389629/projects`
3. The number (4389629 in this example) is your account ID

## Security Notes

- Keep your `.env` file secure and never commit it to version control
- The OAuth tokens are stored locally in `oauth_tokens.json`
- This setup is designed for local development use
