## 🚀 Quick Start

### 1. Installation

1. **Clone this repository**:
   ```bash
   git clone https://github.com/robcerda/monarch-mcp-server.git
   cd monarch-mcp-server
   ```

2. **Install dependencies**:
   ```bash
   pip install -r requirements.txt
   pip install -e .
   ```

3. **Configure Claude Desktop**:
   Add this to your Claude Desktop configuration file:
   
   **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
   
   **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
   
   ```json
   {
     "mcpServers": {
       "Monarch Money": {
         "command": "/opt/homebrew/bin/uv",
         "args": [
           "run",
           "--with",
           "mcp[cli]",
           "--with-editable",
           "/path/to/your/monarch-mcp-server",
           "mcp",
           "run",
           "/path/to/your/monarch-mcp-server/src/monarch_mcp_server/server.py"
         ]
       }
     }
   }
   ```
   
   **Important**: Replace `/path/to/your/monarch-mcp-server` with your actual path!

4. **Restart Claude Desktop**

### 2. One-Time Authentication Setup

**Important**: For security and MFA support, authentication is done outside of Claude Desktop.

Open Terminal and run:
```bash
cd /path/to/your/monarch-mcp-server
python login_setup.py
```

Follow the prompts:
- Enter your Monarch Money email and password
- Provide 2FA code if you have MFA enabled
- Session will be saved automatically

### 3. Start Using in Claude Desktop

Once authenticated, use these tools directly in Claude Desktop:
- `get_accounts` - View all your financial accounts
