Overview

AI-generated overview

A local MCP server that imports a bank CSV into a private ledger, categorises transactions, summarises per currency and reconciles against expense receipts.

What you can do
Import bank CSV exports, detecting header, date, amount and currency columns, locale number formats and duplicates, and list imported accounts with balances and date ranges. List and search transactions by date range, account, category or text, with totals per currency. Set category rules and assign categories to transactions by id. Summarise money in, money out and net by category, month, account or counterparty, always per currency. Detect recurring charges and subscriptions with cadence and annualised cost, and reconcile bank debits against receipts in a companion expense tracker. Export a range to CSV or JSON (Pro only).
When to use it
Useful for month-end personal or small-business bookkeeping in chat: turning a bank export into a readable, categorised ledger, spotting uncategorised spending and subscriptions, and checking which debits lack receipts. It suits users who want their statement data to stay on their own machine rather than in an accounting SaaS.
Requirements
Runs locally over stdio, desktop only. The npm package is described as not yet published, so install via the .mcpb bundle or a clone-and-build with Node.js and npm. No accounts, API keys or environment variables are declared. A Pro license key (MCP_LICENSE_KEY or license_activate) is optional and unlocks more accounts, full history, unlimited rules and export.
Before you install
It handles sensitive bank statement data; the README says everything is stored as a plain JSON file under the local data directory and that the server makes no network calls, but that claim should be verified before trusting it with real statements. Import writes to the local ledger, setting rules re-applies them to stored transactions, and export can overwrite an existing file. Pro is a paid one-time license; free mode limits accounts, history, rules and export.

Installation

In SourceWeft

  1. Open Bank Statement in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

[bank-statement demo]

Export the CSV from your bank, say "import this", and the month is readable. This MCP server turns a bank export into a local ledger: it finds the header row under whatever preamble the bank prints above it, works out which column is the date, which is the money and which way the money went, and reads amounts in the file's own locale, so 1 234,56 from mBank and 1,234.56 from a US bank both become the same number. A debit is stored negative and a credit positive, once, at import, so nothing downstream has to guess. Re-importing the same export adds nothing: every line carries a hash of its date, amount, currency and description, with an occurrence index, so two identical coffees on one day stay two transactions while a second import of the same file stays zero. Your rules categorise transactions as they arrive, summaries report money in, money out and the net per currency and never mix currencies, recurring_detect finds the subscriptions and what each costs per year, and reconcile_expenses matches bank debits against the receipts in mcp-expense-tracker so you can see which debits have no receipt and which receipts never reached the bank. Everything is a plain JSON file on your own machine; nothing is uploaded anywhere.

Turn a bank CSV into a categorised, reconciled month in chat, no accounting SaaS required.

Bank profiles: Revolut, Wise, mBank, PKO BP, ING, N26, and a generic reader that works from the headers alone.

File shapes it reads without being asked: UTF-8 and UTF-16 (either byte order, as Excel on Windows saves it), CRLF, LF and CR-only line endings, quoted fields holding commas, quotes and newlines, 1.234,56 and 1,234.56, accounting parentheses (12.50) and a trailing minus 12.50- (both negative), and a mixture of currencies inside one file. A cell holding - or nothing is skipped and named in skipped_lines rather than read as zero. When the date column is ambiguous (03/04/2026 with no value above 12 anywhere), the assumed order is stated in the response instead of silently picking one.

60-second install

npm publish for @theluckystrike/mcp-bank-statement 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 bank-statement.mcpb from the latest release and double-click it in Claude Desktop: https://github.com/theluckystrike/mcp-servers/releases/latest

(claude_desktop_config.json):

json
{  "mcpServers": {    "bank-statement": {      "command": "npx",      "args": ["-y", "@theluckystrike/mcp-bank-statement"]    }  }}

Claude Code:

sh
claude mcp add bank-statement -- npx -y @theluckystrike/mcp-bank-statement

(.cursor/mcp.json):

json
{  "mcpServers": {    "bank-statement": {      "command": "npx",      "args": ["-y", "@theluckystrike/mcp-bank-statement"]    }  }}

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:

sh
git clone https://github.com/theluckystrike/mcp-servers.git && cd mcp-serversnpm installnpm run build -w packages/mcp-license -w servers/spreadsheet -w servers/bank-statement

Then point your client's command at node with one arg: the absolute path to servers/bank-statement/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

ToolWhat it does
statement_importRead a bank CSV into the ledger. Detects the header row under any preamble, the date, description, amount (or debit and credit) and currency columns, the date order and the number locale. Reports what it detected, what it stored, how many lines were duplicates of what is already there, and every line it skipped with the reason
transactions_listList transactions in a date range, filtered by account, category or uncategorized, with totals per currency
transactions_searchFind transactions whose description, counterparty, category or account contains the query. Substring only, never a regex
category_rulesSet or list the rules that categorise transactions. An empty match is refused, because it would stamp one category on the whole ledger. A plain match is a case-insensitive substring; regex: true compiles the pattern only if it cannot backtrack exponentially, and (a+)+ is refused and used as a substring. Setting rules re-applies them to stored transactions
transaction_categorizeSet the category on transactions by id. Nothing changes unless every id exists
statement_summaryMoney in, money out and the net for a range, grouped by category, month, account or counterparty, always per currency
reconcile_expensesMatch bank debits against the receipts in mcp-expense-tracker: same currency, same amount, within a date window. Reports matches, bank lines with no receipt, and receipts that never reached the bank. The expense ledger is only ever read
recurring_detectFind subscriptions and recurring charges: the same counterparty, an amount that barely moves, a steady cadence. Reports the cadence, the typical amount, the next expected date and the annualised cost. Two charges are one interval, so the yearly cost is withheld (cadence_confirmed: false) until a third charge confirms it
statement_exportWrite a range to csv or json and return the path. Written atomically, so a failure never leaves a half file. Replacing an existing file is allowed and reported (overwrote_existing_file)
accounts_listThe imported accounts, with bank, currencies, transaction count, date range and last balance
license_statusShow free or Pro mode
license_activateActivate a Pro key (verified offline)

Resource bank://month returns this month's money in, money out and net, grouped by category, per currency. Prompt monthly_review drives the whole month-end pass: totals, uncategorised lines, subscriptions, reconciliation.

Import always stores every row, whatever the tier: silently dropping lines on the way in would make the ledger disagree with the bank. The free limit is on what is read back.

Get Pro: https://mcp.zovo.one/buy/bank-statement, $19 one-time for this server, $39 for every server, lifetime. Keys are verified offline; nothing is sent anywhere.

Pairs with

  • mcp-expense-tracker, log the receipts and the mileage; reconcile_expenses reads that ledger and tells you which bank debits have no receipt behind them.
  • mcp-spreadsheet, this server parses your bank CSV with the spreadsheet server's own RFC 4180 reader and locale number parser, so 1 234,56 means the same thing in both. Use it to slice an exported range.
  • mcp-invoice, the income side: raise the invoice, then watch the payment land in statement_summary grouped by counterparty.

Privacy

Everything stays on your machine. Statements are parsed locally and stored in a plain JSON file under ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/bank-statement/. The server makes no network calls at all, not for licensing, not for parsing, not for anything. Deleting that directory resets it.
