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.

[!NOTE] Copilot Money now has an official MCP server. It is read-only, with write support announced as coming later, and connects to MCP clients over OAuth. If a first-party, read-only integration suits your needs, you should strongly consider using it instead of this community project. Setup instructions: Setting up the MCP.

This project remains useful if you need write tools today (categorize transactions, manage budgets, edit recurrings, etc.) or fully offline cache-mode reads with zero network requests.

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.

14 cache-mode read tools (or 25 in --live-reads mode: 8 surviving cache + 17 live), plus up to 19 write tools — query and modify transactions, accounts, holdings, balances, categories, recurring charges, budgets, goals, and investment performance. See Tools by Mode below.

Contributors: writes go through an API we don't own. How the repo keeps its model of Copilot's GraphQL surface from silently drifting — the conformance ledger, live smokes, and weekly drift check — is documented in docs/CONFORMANCE_ARCHITECTURE.md.

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

[!IMPORTANT] Heads up about AI providers. While this server itself runs locally and never sends your data to any server operated by this project, the AI assistant you connect it to (Claude, ChatGPT, Gemini, etc.) will see your Copilot Money data as part of answering your questions. That means your financial data will be transmitted to and processed by the provider of whichever model you choose — Anthropic, OpenAI, Google, or another third party — subject to that provider's own privacy policy and data retention terms.

By using this MCP server with a hosted AI model, you are knowingly sharing your financial data with that AI provider. Only use this tool if you are comfortable with that trade-off. If you are not, consider using a fully local model.

Tools by Mode

This server exposes different tools depending on which CLI flags you enable.

Passing --write implies --live-reads; you can still pass --live-reads on its own for read-only live access.

📖 See docs/tools-by-mode.md for the full per-tool inventory with status, caveats, and known limitations (goals, stock splits, response-size caps).

⬆️ Upgrading from v2? v3.0.0 changed the shape of read responses — see docs/MIGRATING-v3.md. No tool was renamed or removed; rows got terse and two arguments were retired.

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
• For --live-reads or --write only: a supported browser logged in to app.copilot.money — the Chromium family, Firefox, or Safari; see docs/graphql-live-reads.md for the list. The server reuses that session's Firebase refresh token. Without it the server still starts, and the first live or write tool call tells the assistant to log in — log in and retry, no restart needed. Default mode needs nothing — it reads the local cache and makes no network requests.

Installation via Claude Desktop

What You Can Do

Spending Analysis

"How much did I spend on dining out last month?"

"Show me all my Amazon purchases in the last 30 days"

"What are my top 5 spending categories this year?"

Uses get_transactions (or get_transactions_live for fresh data via --live-reads) and get_categories (or get_categories_live), with date ranges, text search, and category filters.

Account Overview

"What's my net worth across all accounts?"

"Show me my checking account balance over the past 6 months, monthly"

"Which bank connections need attention?"

Uses get_accounts (or get_accounts_live for fresh balances via --live-reads), get_balance_history (with optional get_balance_history_live per-account live variant), get_connection_status, and get_networth_live for net-worth-over-time charts.

Investment Portfolio

"What are my current holdings and total returns?"

"Show me the price history for my largest equity holding over the past year"

"What's my current cost basis on META?"

Uses get_holdings (or get_holdings_live for live cost basis), get_investment_prices (or get_investment_prices_live for live per-security price history).

Budgets & Goals

"Am I on track with my budgets this month?"

"How is my emergency fund progressing?"

"Show me my goal history over the past 6 months"

Uses get_budgets (or get_budgets_live via --live-reads), and get_goals / get_goal_history (cache-only — Copilot's GraphQL endpoint doesn't expose goal data).

Subscriptions & Recurring

"What subscriptions am I paying for?"

"How much do I spend on recurring charges per month?"

Uses get_recurring_transactions (or get_recurring_live via --live-reads) and get_upcoming_recurrings_live for next-due unpaid items.

Configuration

Cache TTL

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

# Set cache TTL to 10 minutesCOPILOT_CACHE_TTL_MINUTES=10 copilot-money-mcp
# Disable caching (always reload from disk)COPILOT_CACHE_TTL_MINUTES=0 copilot-money-mcp
# Write tools resolve account/item ids for a transaction id via a live# window fetch when the in-memory index (fed by live reads) misses.# Default window: 13 months. Raise it to edit older transactions:COPILOT_WRITE_RESOLVE_WINDOW_MONTHS=30 copilot-money-mcp --write
# Write-resolution routing ids (opaque transaction/account/item ids only —# never amounts or names) persist whenever live reads are enabled (including# --write mode), keyed by the logged-in account, so cross-session writes# skip the live window fetch.# The same switch also disables the persisted split-parent record# (split-parents.<uid>.jsonl, opaque ids only): delete_transaction then# remembers a parent split through this server only until it restarts, and# after a restart relies on the local cache to refuse it (#842).# Disable both entirely:COPILOT_DISABLE_PERSISTENT_INDEX=1 copilot-money-mcp --write

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 variableDECODE_TIMEOUT_MS=600000 copilot-money-mcp
# Via CLI flagcopilot-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

Authentication & Optional Modes

Both --live-reads and --write make authenticated calls to Copilot Money's GraphQL API at app.copilot.money/api/graphql. They require a logged-in browser session against app.copilot.money — the server reads the same Firebase refresh token the web app stores in your browser. Ten browsers are searched — Chrome, Arc, Microsoft Edge, Brave, Vivaldi, Chromium, Opera, Opera GX, Safari, and Firefox — and each Chromium-family browser across every one of its profiles, not just the default one. See PRIVACY.md for exactly which files are read and why the browser-wide Local Storage read is not scoped to Copilot's origin.

On Linux the Linux locations are searched instead: Chrome (~/.config/google-chrome, plus -beta / -unstable), Microsoft Edge (~/.config/microsoft-edge), Brave (~/.config/BraveSoftware/Brave-Browser), Vivaldi (~/.config/vivaldi), Chromium (~/.config/chromium and the snap's ~/snap/chromium/common/chromium), Opera (~/.config/opera), and Firefox (~/.mozilla/firefox, ~/.config/mozilla/firefox where Firefox 147+ creates new profiles when there is no ~/.mozilla, the snap's ~/snap/firefox/common/.mozilla/firefox, and the flatpak's ~/.var/app/org.mozilla.firefox/.mozilla/firefox). The ~/.config locations honour XDG_CONFIG_HOME. Arc, Safari and Opera GX are macOS-only.

Choosing the browser and profile: --browser / --browser-profile

By default the browsers above are tried in that fixed order and the first working session wins. If more than one Copilot account is logged in on the machine — say one person in Brave and another in Chrome — pin the one to use:

Each flag wins over its environment variable. With a browser selected, only that browser (and, with a profile, only that profile) is read — there is no fallback to the others, so the session can never silently come from someone else's browser. If nothing is found, the error names exactly what was searched, e.g. No Copilot Money session found in Brave (profile "Default"). …, and says so when the browser's data directory or the profile does not exist.

A profile name must pick exactly one profile. Display names are not unique, and Microsoft Edge's built-in ones are off by one from its directories (directory Default is shown as "Profile 1", directory Profile 1 as "Profile 2"), so a name that matches one profile's directory and another's display name — or two display names, or two Firefox profiles — is refused, and nothing is searched: --browser-profile "Profile 1" is ambiguous in Microsoft Edge: it matches directory "Profile 1" and the display name of directory "Default". Pick exactly one with --browser-profile "dir:Default" or "dir:Profile 1". Every value the refusal offers selects exactly one profile: a Firefox profile that profiles.ini keeps outside the profiles directory is offered as name: instead, since dir: only sees listed directories, and two Firefox profiles that no name tells apart (the same directory name directly in a --browser-data-dir and under its Profiles/, or two profiles.ini entries with one Name= kept outside the profiles directory) are named by path: select one by dropping --browser-profile and pointing --browser-data-dir at it. The dir: form always names exactly one profile, so on a stock Edge with three or more profiles — where every middle Profile N is both a directory and another profile's display name — every profile stays selectable. A directory whose own display name is the same string is not ambiguous. On Linux, an ambiguity inside any one Chrome channel refuses the whole selection, and the message names that channel's directory.

The selection only applies with --live-reads or --write. There, an unknown browser name, a profile without a browser, a macOS-only browser on Linux, or a bad --browser-data-dir stops the server at startup with an error. In the default cache-only mode no browser is read, so a selection — from flags or from the environment, valid or not — is ignored with a one-line warning on stderr instead of stopping the server.

With --browser-data-dir, only that directory is read — not the browser's default locations and not any other browser. --browser-profile then matches profiles inside it (directory name, Local State display name, Firefox suffix or profiles.ini Name=, with relative Path= entries resolved against the data dir). Pointed at a single Firefox profile, no --browser-profile is needed, and one that names a different profile is refused. The server refuses to start if the path does not exist or is not a directory, if no browser is given, or if the browser is Safari (whose locations are fixed by macOS). If the directory holds no session, the error names it: No Copilot Money session found in Chrome (data dir "/home/me/chrome-profile/Fork-18"). …, and if the path looks like one Chromium profile (it is named Default / Profile N or holds a Preferences file) rather than the user-data root above it, the error says so and suggests the parent plus --browser-profile.

{  "mcpServers": {    "copilot-money": {      "command": "copilot-money-mcp",      "args": ["--live-reads", "--browser", "brave", "--browser-profile", "Default"]    }  }}

Or, equivalently, "env": { "COPILOT_BROWSER": "brave", "COPILOT_BROWSER_PROFILE": "Default" } in the same entry. For a Chrome started with a custom --user-data-dir:

"args": ["--live-reads", "--browser", "chrome", "--browser-data-dir", "/home/me/chrome-profile/Fork-18"]

Default mode requires no authentication and makes zero network requests — reads come from the local LevelDB cache.

--live-reads: real-time reads via GraphQL

copilot-money-mcp --live-reads

Replaces 6 cache-mode read tools (get_transactions, get_accounts, get_categories, get_budgets, get_recurring_transactions, get_holdings) with live GraphQL-backed equivalents, and adds 11 net-new ones (get_tags_live, get_networth_live, get_upcoming_recurrings_live, get_monthly_spend_live, get_balance_history_live, get_investment_prices_live, refresh_cache, get_investment_allocation_live, get_top_movers_live, get_aggregated_holdings_live, get_investment_balance_live).

Use this when:

• You need transactions the macOS app hasn't pre-fetched yet (the auto-fetch window is typically ~30 days; past that, open the app and scroll back to force the cache to populate, or use --live-reads to query the server directly).
• You want fresh per-security cost basis or balance-over-time data.
• The macOS app hasn't synced recently.

--write: mutations via GraphQL (implies --live-reads)

copilot-money-mcp --write

Adds 19 mutation tools for transactions, tags, categories, recurrings, budgets, and split-transactions. Off by default — the server is read-only unless you opt in.

--write automatically enables --live-reads as well. Write tools resolve transaction metadata (account/item IDs) against the live GraphQL surface so they can edit any transaction the API exposes, not just the ~30 days the local LevelDB cache happens to hold. Once you've consented to the authenticated network calls writes require, there's no privacy or perf reason to keep reads pinned to the stale cache.

copilot-money-mcp --write --live-reads   # equivalent to `--write` alone; --live-reads is redundant

Configuring via Claude Desktop / Cursor

Add the flags to the args array in your MCP config:

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

Restart Claude Desktop / Cursor after editing.

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.

Goals are read-only

get_goals and get_goal_history work (cache-only), but there are no goal write tools — Copilot's GraphQL endpoint doesn't expose goal mutations. Goal creation, editing, and contributions are mobile-only in Copilot itself, and live in a path our project can't reach without iOS / desktop traffic capture.

Investment splits are limited to currently-held securities

get_investment_splits returns split events (date + adjustment multiplier) for securities you currently hold. Securities you no longer hold eventually fall out of the cache. There's no GraphQL endpoint for splits, so this is the only path.

Also: get_investment_prices and get_investment_prices_live already return split- and dividend-adjusted prices (Copilot applies Plaid's adjustment factors server-side). You generally don't need raw split events to back-correct prices.

Live investment prices are ownership-gated

get_investment_prices_live only works for securities currently in your linked accounts. Asking for a price series on a ticker you don't own returns an explicit "not in your linked accounts" error.

Long time-series responses are capped

Time-series live tools (get_balance_history_live, get_networth_live, get_investment_prices_live) cap responses at 500 rows by default to fit the MCP single-tool-result token limit. Pass max_rows / offset to paginate, or narrow time_frame for fewer rows.

get_investment_balance_live has its own, much tighter cap under a different name: history_limit, default 30 points, 0 for the whole series. Its responses always report history_total_count and history_truncated, and its current value is resolved separately so it can never be lost to truncation.

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
