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. Optional write mode (opt-in via --write) sends your requested changes directly to Copilot Money's Firebase/Firestore backend — the same backend the Copilot Money app itself uses — authenticated with your own credentials, never through any third-party service.

35 tools across spending, investments, budgets, goals, and more:

• 17 read tools — query transactions, accounts, holdings, balances, categories, recurring charges, budgets, goals, investment performance, and more

• 18 write tools (opt-in) — consolidate transaction changes, manage tags, create budgets, update recurring items, and organize your finances

Read-only by default. Write tools require explicitly starting the server with --write to enable.

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

• Read-only by default (write tools disabled unless you pass --write)

• In opt-in write mode, requests go directly from your machine to Copilot Money's own Firebase/Firestore backend using your own credentials — never through any third-party service

• Open source — verify the code yourself

Available Tools

Read Tools (17)

Write Tools (18) — requires --write flag

Write Mode

By default, the server starts in read-only mode. To enable write tools, start the server with the --write flag:

{
  "mcpServers": {
    "copilot-money": {
      "command": "copilot-money-mcp",
      "args": ["--write"]
    }
  }
}

Write tools modify your Copilot Money data by sending authenticated requests directly to Copilot Money's Firebase/Firestore backend — the same backend the Copilot Money app uses — so your changes are immediately reflected in your account. Writes authenticate using a Firebase refresh token extracted from your local Copilot Money session; your credentials never leave your machine except in the authenticated request to Google's Firebase/Firestore endpoints. No third-party services are involved. See PRIVACY.md for full details.

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
