Zovo Expense Tracker MCP Server

All servers · Buy Pro $19 · All 46 for $39 · Source

Two ways to run it, both free to start. Open mcp.zovo.one/mcp/connect, copy the expense-tracker URL and paste it into any client that takes a URL. It already carries a free token, so there is nothing to install, no account and no header to set. The URL is https://mcp.zovo.one/mcp/expense-tracker/t/<token>. The token is not optional: the bare https://mcp.zovo.one/mcp/expense-tracker connects and lists its tools and then answers every tool call with HTTP 401, so use the link from /mcp/connect or send Authorization: Bearer <token>. Or download expense-tracker.mcpb and double-click it in Claude Desktop.

Log expenses from Claude with a free MCP server

In the official MCP Registry (io.github.theluckystrike/expense-tracker-receipts-mileage).

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 (set it once with expense_settings and every later expense is split without repeating it), 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_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/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

Tool	What it does
expense_add	Log one expense: amount, currency, category, merchant, date, project, note, receipt path, billable flag, VAT rate. An empty category is filled in from the merchant rules. billable defaults to true when a project is given and false otherwise, and the response always states which value was used
expense_settings	Read or set the defaults expense_add uses when a call names none: default_vat_rate, default_currency
expense_list	List expenses in a date range, filtered by project, category or billable, with totals per currency
expense_update	Change any field of a stored expense by id. rebilled: false clears both the rebilled marker and the invoice number. Amount, currency and vat_rate are refused on an expense already rebilled unless you pass unlink_rebill: true, which clears the rebill link, because the invoice charged something else
expense_delete	Delete one expense by id. The receipt file itself is left alone
receipt_attach	Attach a receipt file to an expense. The file must exist; its path and sha256 are stored
category_rules	Set or list the merchant-to-category rules. A match with no regex metacharacters is a plain substring; one with them is compiled only if it cannot backtrack exponentially, and a pattern like (a+)+ is refused
expense_summary	Totals for a range grouped by category, project, month or merchant, with the gross, net and VAT per currency
mileage_add	Log a trip in km or miles and price it from the rate table (or your own rate)
expense_export	Write the range to csv, xlsx or json and return the path. Never writes a partial file
expense_to_invoice	Preview a project's unbilled billable expenses as invoice_create line items, per currency, with an optional markup and an optional assume_vat_rate. Pass target_currency + fx_rates to fold every currency into one group. When nothing matches it returns count: 0, no fx_note, and the plain reason. Marks nothing as rebilled, ever
expense_mark_rebilled	Mark expenses rebilled once the invoice exists, by ids or by project, date range and currency. invoice_number is required
license_status	Show free or Pro mode
license_activate	Activate a Pro key (verified offline)

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

The table holds one flat rate per region. Each row is an approximation with a stated assumption, not a tax calculation:

Region	Rate	Unit	Currency	What it assumes
PL	1.15	km	PLN	A car over 900 cm3. The Polish limit is PLN 0.89/km up to 900 cm3, and there are separate motorcycle and moped rates
UK	0.45	mile	GBP	A car, within the first 10,000 business miles of the tax year. HMRC pays a lower rate above that threshold, and different rates for motorcycles and bicycles
US	0.70	mile	USD	The IRS business standard rate for one calendar year. The IRS re-issues it every year, and has changed it mid-year
EU	0.30	km	EUR	A generic per-kilometre allowance. There is no single EU rate; each member state sets its own

There are deliberately no year, vehicle or threshold tables behind these numbers: a table that looks authoritative but is a year out of date is worse than one that says what it is. Every mileage_add reply names the rate it used and repeats that caveat, for example (table rate PL 1.15 PLN/km, an approximation; pass rate_per_km for your exact scheme).

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, which is the supported way to claim an exact scheme (an engine class, a mid-year rate, the band above 10,000 miles). currency is only accepted together with rate_per_km: a table rate is quoted in its own currency, and relabelling PLN 1.15/km as EUR 1.15/km would convert nothing and book roughly four times the real cost, so that call is refused.

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 recorded on the expense, so the invoice recomputes the same tax rather than double-charging it, and the line total comes back to the gross on the receipt. Where rounding the tax a second time cannot reproduce that gross (EUR 0.03 at 23% splits into 0.02 + 0.01, but 0.02 taxed at 23% rounds to 0.00), the unit_price is nudged by the one cent if that lands the invoice exactly, and otherwise the group carries a visible [rounding adjustment ...] line at tax_rate: 0; rounding_adjustment_lines counts them.

Mixed currencies

One invoice carries one currency, so a week of USD hours, a EUR receipt and a GBP mileage line comes back as three groups. To get a single invoice, supply the target and your own rates:

expense_to_invoice {project: "Nova", from: "2026-09-01", to: "2026-09-07",
                    target_currency: "USD", fx_rates: {"EUR": 1.08, "GBP": 1.27}}

fx_rates reads as "1 unit of that currency = X units of target_currency ". Every line is converted and one group is returned, and each converted line says so on its own face: ... [converted from EUR 12.40 at 1.08]. Nothing here fetches or invents a rate; a currency with no rate is refused by name. Without fx_rates, a mixed range returns the exact call to make instead of leaving you to work it out.

A stored vat_rate of 0 is a rate, not a gap: an exempt receipt stays exempt. An expense recorded with no rate holds a gross amount, and it is rebilled as-is with tax_rate: 0 and tax_rate: 0 (VAT unknown, gross rebilled as-is; pass assume_vat_rate to split) in the description, so a default rate on the invoice cannot tax the receipt twice. The expense_settings default is applied when the expense is inserted and never retroactively at rebill time: changing that default later must not rewrite the tax meaning of receipts entered before it existed. To split those older lines anyway, pass assume_vat_rate explicitly on the expense_to_invoice call and the lines are flagged [vat assumed 23%].

Nothing is marked rebilled by that call, and there is no option to make it: create the invoice first, then call expense_mark_rebilled with a required invoice_number. Because one invoice carries one currency, the result is grouped per currency, each group carries its own expense_ids, and you pass one group. Marking by ids is the precise route; marking by project and date range additionally requires currency, and touches only billable, not-yet-rebilled expenses in it, so invoicing the EUR group cannot mark the PLN one. mcp-time-tracker bills the hours on the same project; this server bills what the project cost you.

Free vs Pro

	Free	Pro
Logging expenses, mileage and receipts	Unlimited	Unlimited
expense_list and expense_summary	Last 30 days	Full history
Projects	3	Unlimited
Category rules	5	Unlimited
CSV and JSON export	Up to 200 rows	Unlimited
xlsx export	No	Yes
expense_to_invoice	20 items at a time, markup_percent included	Unlimited items

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 in the expense's own currency, and every printed amount carries its currency code, for example EUR 61.50. How many minor units make one unit comes from an ISO 4217 table, not a guess: 2 for most currencies, 0 for JPY, KRW, VND, CLP, ISK and the rest of the zero-decimal list, 3 for BHD, IQD, JOD, KWD, LYD, OMR and TND, 4 for CLF and UYW. So KWD 1.234 is 1234 minor units, not 123. The same table is used by mcp-invoice, because the two servers exchange amounts. HUF is 2 decimals here: ISO 4217 gives it two minor digits even though it is usually quoted without them.

The amount you record is the gross on the receipt. vat_rate splits it by rounding the VAT, not the net: vat = round(gross * rate / (100 + rate)), net = gross - vat, so net plus VAT is always exactly the gross and a half-cent of VAT rounds up instead of disappearing (EUR 0.03 at 23% is net 0.02 plus VAT 0.01). 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

If data.json is ever unreadable or not valid JSON, it is not treated as "no expenses yet". The file is moved aside byte-for-byte as data.json.corrupt-<timestamp>, a data.json.corrupt marker is written, and every tool returns data file is corrupt; moved to ...; nothing was written until you restore a good copy and delete the marker, so a truncated file can never be overwritten by an empty database.

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.

Built by theluckystrike.

One business profile for the whole suite

Your identity is stored once, at ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/profile/business.json, and every server in the suite reads it: the invoice issuer, the docx letterhead, the recurring issuer, expense-tracker's default VAT rate, time-tracker's and timezone's home zone, and the resume and contract letterheads. Set it once with business_set (invoice or docx) - you never repeat it anywhere else. An email address is only ever taken from that profile or from an explicit argument; when none is stored, documents show [add: email] and the tool says so rather than letting anyone improvise an address.

Frequently asked questions

Is there a free MCP expense tracker?

Yes. The expense-tracker server at mcp.zovo.one is a free MCP expense tracker: log expenses from Claude or any MCP client with categories, amounts and dates, then list or export them. Free tier, remote hosted endpoint, nothing to install.

How do I log an expense from Claude?

Connect https://mcp.zovo.one/mcp/expense-tracker (tokenized URL from mcp.zovo.one/mcp/connect) and say: 'Log 42.50 EUR for client lunch, category meals.' The entry is stored locally-first on your machine.
