Copilot Money MCP Server

Query and manage your personal finances with AI using local Copilot Money data

Disclaimer

This is an independent, community-driven project and is not affiliated with, endorsed by, or associated with Copilot Money or its parent company in any way. This tool was created by an independent developer to enable AI-powered queries of locally cached data. "Copilot Money" is a trademark of its respective owner.

Overview

An MCP server that gives AI assistants access to your Copilot Money personal finance data. It reads from the locally cached Firestore database (LevelDB + Protocol Buffers) on your Mac. Reads are 100% local with zero network requests.

17 read tools across spending, investments, budgets, goals, and more — query transactions, accounts, holdings, balances, categories, recurring charges, budgets, goals, and investment performance.

Privacy First

We never collect, store, or transmit your data to any server operated by this project — we don't have any. See our Privacy Policy for details.

• No analytics, telemetry, or tracking of any kind
• Reads are fully local — zero network requests
• Open source — verify the code yourself

Quick Start

Prerequisites

• Node.js 18+ (comes bundled with Claude Desktop)
• Copilot Money (macOS App Store version)
• Claude Desktop, Cursor, or any MCP-compatible client

Installation via Claude Desktop

1. Download the latest .mcpb bundle from Releases
2. Double-click the .mcpb file to install in Claude Desktop
3. Restart Claude Desktop
4. Start asking questions about your finances!

Installation via npm

npm install -g copilot-money-mcp

Then add to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "copilot-money": {
      "command": "copilot-money-mcp"
    }
  }
}

Installation for Cursor

1. Install the package globally:

   npm install -g copilot-money-mcp
   

2. Open Cursor Settings (Cmd + ,) > Features > MCP Servers

3. Add the server configuration:

   {
     "mcpServers": {
       "copilot-money": {
         "command": "copilot-money-mcp"
       }
     }
   }

Configuration

Cache TTL

The server caches data in memory for 5 minutes. Configure via environment variable:

# Set cache TTL to 10 minutes
COPILOT_CACHE_TTL_MINUTES=10 copilot-money-mcp

# Disable caching (always reload from disk)
COPILOT_CACHE_TTL_MINUTES=0 copilot-money-mcp

You can also refresh manually using the refresh_database tool.

Decode Timeout

For large databases (500MB+), increase the decode timeout (default: 90 seconds):

# Via environment variable
DECODE_TIMEOUT_MS=600000 copilot-money-mcp

# Via CLI flag
copilot-money-mcp --timeout 600000

For databases over 1GB, also increase Node.js memory:

{
  "mcpServers": {
    "copilot-money": {
      "command": "node",
      "args": [
        "--max-old-space-size=4096",
        "/path/to/copilot-money-mcp/dist/cli.js",
        "--timeout", "600000"
      ]
    }
  }
}

Supported Date Periods

The period parameter supports these shortcuts:

this_month last_month last_7_days last_30_days last_90_days ytd this_year last_year

Known Limitations

Local Cache Dependency

This server reads from Copilot Money's local Firestore cache, not the cloud. Firestore's offline persistence caches every document the app has ever fetched, so the local database generally contains all transactions, accounts, budgets, goals, and other data you've viewed in the app. The default Firestore cache size is 100 MB (enough for tens of thousands of transactions), and older documents are only evicted via LRU garbage collection if that limit is exceeded.

To maximize cached data: Open the Copilot Money app and browse through your data (transaction history, accounts, budgets) to ensure it has been fetched and cached locally.

Troubleshooting

Database Not Found

If you see "Database not available":

1. Ensure Copilot Money is installed and has synced data
2. Check the database location: ~/Library/Containers/com.copilot.production/Data/Library/Application Support/firestore/__FIRAPP_DEFAULT/copilot-production-22904/main
3. Verify .ldb files exist in the directory
4. Provide a custom path: copilot-money-mcp --db-path /path/to/database

Decode Worker Timed Out

If you see "Decode worker timed out":

1. Increase the timeout: copilot-money-mcp --timeout 300000 (5 minutes)
2. For 1GB+ databases, also increase Node.js memory: node --max-old-space-size=4096 dist/cli.js --timeout 300000

No Transactions Found

• Open the Copilot Money app and wait for sync
• The database structure may have changed — open an issue
