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

# 1. Install uv (if not already installed)
curl -LsSf https://astral.sh/uv/install.sh | sh

# 2. Clone and install
git clone https://github.com/jcvalerio/moneywiz-mcp-server.git
cd moneywiz-mcp-server
uv sync --all-extras

# 3. Find your MoneyWiz database
uv run python setup_env.py

# 4. Add to Claude Desktop config and restart

See Claude Desktop Setup below for the exact JSON configuration.

✨ What You Can Do

Ask Claude natural language questions about your finances:

💰 Account & Transaction Management

• "Show me all my MoneyWiz accounts with their balances"
• "Get details for my checking account including recent transactions"
• "Search my transactions from last month in the Groceries category"

📊 Expense Analytics

• "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?"

💡 Advanced Analytics

• "Give me personalized savings recommendations with 25% target rate"
• "Analyze my spending trends over the last 6 months"
• "Show me category trends for my top 5 spending categories"
• "Track my income vs expense trends for financial health"

📅 Scheduled Transactions & Recurring Payments

• "Show me all my scheduled transactions"
• "What recurring payments do I have coming up?"
• "Analyze how my next salary covers my commitments"
• "When will my subscriptions and loans end?"

💵 Budget Management

• "Show me all my budgets with spending status"
• "Am I on track with my monthly budgets?"
• "Compare my budgeted amounts vs actual spending"
• "Which budgets are at risk of going over?"

📋 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
• uv: Install the uv package manager — it manages Python automatically, no separate Python install required

  curl -LsSf https://astral.sh/uv/install.sh | sh
  

• Claude Desktop: Install Claude Desktop application

No system Python required. uv downloads and manages Python 3.12 automatically when you run uv sync.

🛠️ Installation

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

# Install all dependencies (creates .venv with Python 3.12 automatically)
uv sync --all-extras

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

⚙️ Configuration

Automatic Setup (Recommended)

uv run 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

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

2. Add MCP Server Configuration

Claude Desktop does not source your shell, so bare commands like python or uv won't be found. You must use the absolute path to the Python binary inside .venv.

{
  "mcpServers": {
    "moneywiz": {
      "command": "/ABSOLUTE/PATH/TO/moneywiz-mcp-server/.venv/bin/python",
      "args": ["-m", "moneywiz_mcp_server"],
      "cwd": "/ABSOLUTE/PATH/TO/moneywiz-mcp-server"
    }
  }
}

Get your absolute path:

echo "$(pwd)/.venv/bin/python"
# Example output: /Users/yourname/dev/moneywiz-mcp-server/.venv/bin/python

The .venv/bin/python binary is self-contained — it does not require Python to be installed globally on your Mac.

The cwd field is required so the server can locate the .env file with your database path.

3. Restart Claude Desktop

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

🧪 Testing

Test Database Connection

uv run 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)
uv run python -m moneywiz_mcp_server

🐛 Troubleshooting

Server Won't Start

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

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

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

Claude Desktop Connection Issues

1. Validate JSON syntax:

   python3 -c "import json; print(json.load(open('$HOME/Library/Application Support/Claude/claude_desktop_config.json')))"
   

2. Verify the .venv Python path exists:

   ls -la /ABSOLUTE/PATH/TO/moneywiz-mcp-server/.venv/bin/python
   

3. Test the exact command Claude Desktop will run:

   /ABSOLUTE/PATH/TO/moneywiz-mcp-server/.venv/bin/python -m moneywiz_mcp_server
   

4. Check file permissions:

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

Common Issues

• "Database not found": Check MONEYWIZ_DB_PATH in .env and use absolute paths
• "Permission denied": Ensure file permissions and MoneyWiz isn't locking the file
• "MCP server not responding": Restart Claude Desktop and verify the .venv/bin/python path is correct
• "No data found": Ensure MoneyWiz has transaction data and is the correct database
• "command not found": Make sure you're using the absolute .venv/bin/python path, not bare python

🔒 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
