What this MCP does

Imports bank transactions, supports categorization rules and manual labels, provides summaries and searches, and reconciles activity against expense records.

accounts_list
List accounts
List the imported accounts: bank, currencies, transaction count, first and last date, and the closing balance when the file carried one. Start here for the account names transactions_list and statement_export take.
Read only Idempotent
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
bank_delete_upload
Delete an uploaded statement
Delete one statement file stored for your token. The transactions already imported from it are kept; transactions_list and the summary still see them.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name'], 'properties': {'name': {'type': 'string', 'maxLength': 70, 'minLength': 1}}, 'additionalProperties': False}
bank_files
List uploaded statements
List the statement files stored for your token, with their sizes.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
bank_upload
Upload a bank statement file
Send a bank export to this hosted endpoint. There is no filesystem here, so instead of a path you upload the file once with bank_upload and then pass its name as `path` to statement_import. Give exactly one of content (the export as text, header row included - this is the normal case for a CSV), content_base64 (the file's bytes, which keeps a UTF-16 export from Excel readable) or url. url: fetch a public file instead of pasting base64 (recommended above about 10 KB): the url is fetched here with a 10 second timeout, at most 3 redirects, public http(s) hosts only, and a 1 MB cap; the fetched file has to be delimited text, so a PDF statement is refused rather than stored. Uploads are kept for your token between calls; bank_files lists them and bank_delete_upload removes one. The request body cap is 256 KB, so a large export pasted as text has to be split by month.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name'], 'properties': {'url': {'type': 'string', 'description': "url: fetch a public file instead of pasting base64 (recommended above about 10 KB). Public http(s) only; private, link-local and this endpoint's own zone are refused"}, 'name': {'type': 'string', 'maxLength': 70, 'minLength': 1, 'description': 'Name to refer to this statement by: 1-64 characters of letters, digits, underscore or dash, e.g. "september"'}, 'content': {'type': 'string', 'description': 'The export as text, including the header row'}, 'content_base64': {'type': 'string', 'description': "The file's bytes, base64-encoded, instead of text"}}, 'additionalProperties': False}
category_rules
Set or list category rules
Read the category rules, or pass rules to REPLACE the whole list. A plain match is a substring; a regex compiles only if it cannot backtrack exponentially. An empty match is refused. Free: 5 rules.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'rules': {'type': 'array', 'items': {'type': 'object', 'required': ['match', 'category'], 'properties': {'match': {'type': 'string', 'maxLength': 200, 'description': 'Text to look for in the counterparty or description, e.g. "spotify"'}, 'regex': {'type': 'boolean', 'description': 'Treat match as a regular expression. A pattern that can backtrack exponentially is refused and used as a substring instead'}, 'category': {'type': 'string', 'maxLength': 120, 'description': 'Category to set, e.g. "software"'}}, 'additionalProperties': False}, 'description': 'The complete rule list; it replaces the stored one. Omit to list the current rules'}, 'reapply_all': {'type': 'boolean', 'description': 'Also overwrite categories set by an earlier rule or by hand. Default false: only uncategorised transactions are touched'}}, 'additionalProperties': False}
license_activate
Activate license
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['key'], 'properties': {'key': {'type': 'string', 'description': 'License key from checkout, MCPL1.<payload>.<signature>'}}, 'additionalProperties': False}
license_status
License status
Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
reconcile_expenses
Reconcile against the expense ledger
Match bank debits against mcp-expense-tracker entries: same currency and amount, date within a few days. Reports matches, unmatched bank lines, expenses never hitting the bank. Read-only. Free: 31 days; Pro: any range.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['from', 'to'], 'properties': {'to': {'type': 'string', 'maxLength': 10, 'description': 'ISO date, inclusive'}, 'from': {'type': 'string', 'maxLength': 10, 'description': 'ISO date, inclusive'}, 'account': {'type': 'string', 'maxLength': 120, 'description': 'Limit to one bank account'}, 'window_days': {'type': 'integer', 'maximum': 31, 'minimum': 0, 'description': 'Allowed gap between the expense date and the bank date, default 3. A card payment usually settles a day or two after the receipt'}}, 'additionalProperties': False}
recurring_detect
Subscriptions and recurring charges in the bank data
Find charges that come back: debits grouped by counterparty and currency with a steady amount and interval, with cadence, typical amount, next due date and annual cost. Free: 3 months, 5 charges.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'months': {'type': 'integer', 'maximum': 60, 'minimum': 1, 'description': 'How far back to look, default 3. Two occurrences are enough to see a cadence, three make it certain'}, 'account': {'type': 'string', 'maxLength': 120, 'description': 'Limit to one account'}, 'min_occurrences': {'type': 'integer', 'maximum': 24, 'minimum': 2, 'description': 'Occurrences required before a charge counts as recurring, default 2'}}, 'additionalProperties': False}
statement_export
Export bank transactions to a file
Export the BANK transactions of a date range (a month, a quarter, a year) as .csv or .json and return a download link valid for one hour. This is the tool for "export September" once a statement has been imported. Nothing partial is ever written.
Read only Idempotent
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['from', 'to', 'format', 'path'], 'properties': {'to': {'type': 'string', 'maxLength': 10, 'description': 'ISO date, inclusive'}, 'from': {'type': 'string', 'maxLength': 10, 'description': 'ISO date, inclusive'}, 'path': {'type': 'string', 'maxLength': 4096, 'description': 'Name for the downloaded file, e.g. september. It comes back as a download link valid for one hour'}, 'format': {'enum': ['csv', 'json'], 'type': 'string', 'description': 'csv for a spreadsheet, json for a program'}, 'account': {'type': 'string', 'maxLength': 120, 'description': 'Limit to one account'}, 'category': {'type': 'string', 'maxLength': 500, 'description': 'Limit to one category'}}, 'additionalProperties': False}
statement_import
Import a bank CSV
Call this tool to read a bank CSV into the local ledger. Columns detected from headers (date, description, amount, currency, balance); amounts use the file's locale; stored lines skipped. Returns detected/stored/skipped.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['path'], 'properties': {'bank': {'enum': ['auto', 'revolut', 'wise', 'mbank', 'pko', 'ing', 'n26', 'generic'], 'type': 'string', 'description': 'Bank profile. Default "auto": the headers decide. "generic" skips profile detection and uses the header heuristics alone'}, 'path': {'type': 'string', 'maxLength': 4096, 'description': 'Name of a statement uploaded with bank_upload'}, 'account': {'type': 'string', 'maxLength': 120, 'description': 'Name for this account, e.g. "business EUR". Default: the file name without its extension. Later imports of the same account are deduplicated against it'}, 'currency': {'type': 'string', 'pattern': '^[A-Za-z]{3}$', 'description': "Currency for rows where the file names none. Defaults to the shared business profile's default_currency, else EUR; the response says which it used"}, 'overwrite': {'type': 'boolean', 'description': 'Delete every transaction already stored for this account before importing, instead of merging. Use it when the bank reissued a corrected export'}}, 'additionalProperties': False}
statement_summary
What I spent, from the bank account
What was spent/received in a date range per the BANK ACCOUNT, grouped by category, month, account or counterparty. For "what did I spend in August" once imported. Totals are per currency, never summed or converted.
Read only Idempotent
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'to': {'type': 'string', 'maxLength': 10, 'description': 'ISO date, inclusive. Default: today'}, 'top': {'type': 'integer', 'maximum': 200, 'minimum': 1, 'description': 'Groups returned per currency, largest net first. Default 25'}, 'from': {'type': 'string', 'maxLength': 10, 'description': 'ISO date, inclusive. Default: the start of the current month'}, 'account': {'type': 'string', 'maxLength': 120, 'description': 'Limit the summary to one account'}, 'group_by': {'enum': ['category', 'month', 'account', 'counterparty'], 'type': 'string', 'description': 'Default category'}}, 'additionalProperties': False}
transaction_categorize
Categorise transactions by id
Set or clear the category on transactions by id, for a one-off no rule is worth writing for. Every id is checked first, so one unknown id refuses the whole call. category_rules matches by text instead.
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['ids', 'category'], 'properties': {'ids': {'type': 'array', 'items': {'type': 'string', 'maxLength': 64}, 'minItems': 1, 'description': 'Transaction ids, as returned by transactions_list or transactions_search'}, 'category': {'type': 'string', 'maxLength': 120, 'description': 'Category to set. Pass an empty string to clear it'}}, 'additionalProperties': False}
transactions_list
List transactions
List stored transactions in a date range, optionally for one account or category, or only the ones no rule has categorised yet. Totals are reported per currency and never added across currencies.
Read only Idempotent
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {'to': {'type': 'string', 'maxLength': 10, 'description': 'ISO date YYYY-MM-DD, inclusive. Default: today'}, 'from': {'type': 'string', 'maxLength': 10, 'description': 'ISO date YYYY-MM-DD, inclusive. Default: the start of the current month'}, 'limit': {'type': 'integer', 'maximum': 1000, 'minimum': 1, 'description': 'Rows returned, default 200. Totals always cover the whole range'}, 'account': {'type': 'string', 'maxLength': 120, 'description': 'Limit to one account, as named at import'}, 'category': {'type': 'string', 'maxLength': 500, 'description': 'Only transactions in this category'}, 'uncategorized': {'type': 'boolean', 'description': 'Only transactions with no category yet'}}, 'additionalProperties': False}
transactions_search
Search transactions
Find transactions whose description, counterparty, category or account contains the query. Case-insensitive substring search, never a regex, so a query with brackets in it cannot hang the server.
Read only Idempotent
Input schema
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['query'], 'properties': {'to': {'type': 'string', 'maxLength': 10, 'description': 'ISO date, inclusive'}, 'from': {'type': 'string', 'maxLength': 10, 'description': 'ISO date, inclusive'}, 'limit': {'type': 'integer', 'maximum': 500, 'minimum': 1, 'description': 'Rows returned, default 100'}, 'query': {'type': 'string', 'maxLength': 200, 'description': 'Text to look for, e.g. "spotify" or "acme"'}}, 'additionalProperties': False}
