MoneyWiz MCP Server

A Model Context Protocol (MCP) server that provides AI assistants like Claude with secure, read-only access to your MoneyWiz financial data for natural language queries and financial analytics.

🚀 Quick Start (30 seconds)

# 1. Install the server
pip install git+https://github.com/jcvalerio/moneywiz-mcp-server.git

# 2. Set up configuration
python setup_env.py

# 3. Add to Claude Desktop config (~/.../Claude/claude_desktop_config.json)
{
  "mcpServers": {
    "moneywiz": {
      "command": "python",
      "args": ["-m", "moneywiz_mcp_server"]
    }
  }
}

# 4. Restart Claude Desktop and ask: "Show me my MoneyWiz accounts"

✨ What You Can Do

Ask Claude natural language questions about your finances:

• "Show me all my MoneyWiz accounts with their balances"
• "Analyze my expenses for the last 3 months by category"
• "What's my savings rate this year?"
• "Which spending category impacts my finances the most?"
• "Search my transactions from last month in the Groceries category"

📋 Prerequisites

• macOS: MoneyWiz MCP Server only supports macOS (MoneyWiz is only available on Apple platforms)
• MoneyWiz App: Install and set up MoneyWiz with some financial data
• Python 3.10+: Ensure Python is installed
• Claude Desktop: Install Claude Desktop application

🛠️ Installation

Option 1: Install from Source (Recommended)

# Clone the repository
git clone https://github.com/jcvalerio/moneywiz-mcp-server.git
cd moneywiz-mcp-server

# Create virtual environment
python -m venv venv
source venv/bin/activate

# Install with dependencies
pip install -e ".[dev,test]"

# Run setup to find your MoneyWiz database
python setup_env.py

Option 2: Install from PyPI (When Available)

pip install moneywiz-mcp-server

⚙️ Configuration

Automatic Setup (Recommended)

# Run the setup script to automatically find and configure your MoneyWiz database
python setup_env.py

The setup script will:

• Search for MoneyWiz databases on your Mac
• Let you select the correct database
• Create a .env file with your configuration
• Provide next steps for testing

Manual Configuration

Create a .env file in the project root:

# MoneyWiz Database Path
MONEYWIZ_DB_PATH=/Users/yourusername/Library/Containers/com.moneywiz.personalfinance-setapp/Data/Documents/.AppData/ipadMoneyWiz.sqlite

# Security Settings  
MONEYWIZ_READ_ONLY=true

# Optional Settings
LOG_LEVEL=INFO
CACHE_TTL=300
MAX_RESULTS=1000

Finding Your MoneyWiz Database

MoneyWiz stores data in these locations on macOS:

# MoneyWiz 3 (most common)
~/Library/Containers/com.moneywiz.mac/Data/Documents/
~/Library/Containers/com.moneywiz.personalfinance/Data/Documents/
~/Library/Containers/com.moneywiz.personalfinance-setapp/Data/Documents/

# MoneyWiz 2
~/Library/Application Support/SilverWiz/MoneyWiz 2/

Search command:

find ~ -name "*.sqlite*" 2>/dev/null | grep -i moneywiz

🖥️ Claude Desktop Setup

1. Find Your Claude Desktop Config

The configuration file is located at:

~/Library/Application Support/Claude/claude_desktop_config.json

2. Add MCP Server Configuration

Choose one of these configurations:

Standard Installation

{
  "mcpServers": {
    "moneywiz": {
      "command": "python",
      "args": ["-m", "moneywiz_mcp_server"]
    }
  }
}

Virtual Environment

{
  "mcpServers": {
    "moneywiz": {
      "command": "/path/to/your/venv/bin/python",
      "args": ["-m", "moneywiz_mcp_server"]
    }
  }
}

With Custom Database Path

{
  "mcpServers": {
    "moneywiz": {
      "command": "python",
      "args": ["-m", "moneywiz_mcp_server"],
      "env": {
        "MONEYWIZ_DB_PATH": "/path/to/your/MoneyWiz.sqlite",
        "MONEYWIZ_READ_ONLY": "true"
      }
    }
  }
}

3. Restart Claude Desktop

Completely quit and reopen Claude Desktop for changes to take effect.

🧪 Testing

Test Database Connection

python -c "
from moneywiz_mcp_server.config import Config
from moneywiz_mcp_server.database.connection import DatabaseManager
import asyncio

async def test():
    config = Config.from_env()
    print(f'Database: {config.database_path}')
    db = DatabaseManager(config.database_path)
    await db.initialize()
    print('✅ Database connection successful!')
    await db.close()

asyncio.run(test())
"

Test MCP Server

# Start the server (should connect via stdio)
python -m moneywiz_mcp_server

Test with Claude Desktop

Try these queries in Claude Desktop:

• "Show me all my MoneyWiz accounts"
• "Analyze my expenses for the last 3 months"
• "What's my current savings rate?"

🐛 Troubleshooting

Server Won't Start

# Check if database file exists
ls -la "/path/to/your/MoneyWiz.sqlite"

# Test configuration
python -c "from moneywiz_mcp_server.config import Config; print(Config.from_env().database_path)"

# Check server logs
python -m moneywiz_mcp_server 2>&1 | head -20

Claude Desktop Connection Issues

1. Validate JSON syntax:

   python -c "import json; print(json.load(open('claude_desktop_config.json')))"
   

2. Test exact command:

   python -m moneywiz_mcp_server
   

3. Check file permissions:

   ls -la "/path/to/your/MoneyWiz.sqlite"
   

Common Issues

• "Database not found": Check MONEYWIZ_DB_PATH and use absolute paths
• "Permission denied": Ensure file permissions and MoneyWiz isn't locking the file
• "MCP server not responding": Restart Claude Desktop and check JSON syntax
• "No data found": Ensure MoneyWiz has transaction data and is the correct database

🔒 Security

• Read-Only Mode: Database opened in read-only mode by default
• Local Access: Only accesses local database files
• No Network: No external network connections
• Privacy: All data processing happens locally
• Validation: All inputs validated before database queries
