mcp-expense-tracker

Say "12.30 euros at Adobe, software, billable to Acme" and it is logged, categorised, VAT-split and ready to rebill. This MCP server keeps a local ledger of your business expenses: every amount is held in integer minor units in its own currency, vat_rate splits the gross on the receipt into net and VAT, merchant rules categorise new expenses on their own, receipts are attached by path and sha256 so an audit can prove the file has not changed, and business trips are priced from a built-in mileage table. Summaries group by category, project, month or merchant, always per currency and never mixed. It exports to CSV, xlsx or JSON, and expense_to_invoice hands the billable expenses of a project to mcp-invoice in exactly the line-item shape invoice_create expects. Everything is stored in a plain JSON file on your own machine; nothing is uploaded anywhere.

Log receipts and mileage in chat, split the VAT, and rebill them onto an invoice -- no expense SaaS required.

60-second install

npm publish for @theluckystrike/mcp-expense-tracker is pending. Until then, the .mcpb one-click bundle or a clone+build is the working path -- both are verified below.

One-click (.mcpb): download expense-tracker.mcpb from the latest release and double-click it in Claude Desktop: https://github.com/theluckystrike/mcp-servers/releases/latest

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "expense-tracker": {
      "command": "npx",
      "args": ["-y", "@theluckystrike/mcp-expense-tracker"]
    }
  }
}

Claude Code:

claude mcp add expense-tracker -- npx -y @theluckystrike/mcp-expense-tracker

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "expense-tracker": {
      "command": "npx",
      "args": ["-y", "@theluckystrike/mcp-expense-tracker"]
    }
  }
}

The npx form above starts working the moment the package is published. Until then, use the .mcpb bundle above, or build from source with exactly these three commands:

git clone https://github.com/theluckystrike/mcp-servers.git && cd mcp-servers
npm install
npm run build -w packages/mcp-license -w servers/expense-tracker

Then point your client's command at node with one arg: the absolute path to servers/expense-tracker/dist/index.js.

To run in Pro mode set MCP_LICENSE_KEY in the same config block, or call license_activate once with your key.

Tools

Resource: expenses://month returns the current calendar month's totals by category, per currency.

Prompt: monthly_close walks the month's totals, the billable expenses not yet invoiced, and the expenses with no receipt attached.

Mileage rates

With no region, miles use the US rate and kilometres the EU rate. rate_per_km overrides the table with your own rate for the unit you passed, and currency sets the currency for that rate. These are convenience defaults, not tax advice: check the rate your own tax authority allows for the year.

Pairs with the rest of the collection

expense_to_invoice returns {description, quantity, unit_price, tax_rate} objects, which is exactly the items array mcp-invoice takes. unit_price is the net amount, tax_rate is the VAT rate, so the invoice recomputes the same tax rather than double-charging it. Because one invoice carries one currency, the result is grouped per currency and you pass one group. mcp-time-tracker bills the hours on the same project; this server bills what the project cost you.

Free vs Pro

A limit never writes a partial file and never silently truncates: the export is refused with nothing on disk, and the tool says what to narrow.

Pro is a one-time $19, or $39 for every server in the collection, lifetime.

Numbers and money

Every amount is an integer number of minor units (cents, or whole yen for zero-decimal currencies such as JPY) in the expense's own currency, and every printed amount carries its currency code, for example EUR 61.50. The amount you record is the gross on the receipt. vat_rate splits it: net = round(gross * 100 / (100 + rate)), vat = gross - net, so net plus VAT is always exactly the gross. Summaries sum already-rounded per-expense values inside one currency; currencies are never added together and never converted. Mileage money is round(distance * rate) in the rate's currency. Dates are ISO YYYY-MM-DD.

Privacy

All data stays local, in ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/expense-tracker/. There are no network calls: receipts are hashed on your machine, exports are written on your machine, and license keys are verified offline with a public key compiled into the package.
