Cash Book MCP server

• ledger_buildFree

  Derive the double-entry ledger for one period in ONE currency from the invoice, credit note, deposit, expense, bank and asset stores, and register it. Nothing is written back. Free: 3 periods a month.

• ledger_export_csvFree

  Return the period's ledger lines as RFC 4180 CSV, one row per leg, as a download link valid for one hour. Pro, but ledger_lines returns these same fields free and unlimited; this only lays them out as CSV columns.

• ledger_linesFree

  List the ledger lines for a period, filtered by account, source server, source_id or date; each carries its debit, credit and bank_ref, with the totals of the rows returned. Filtered totals do not balance. Free.

• ledger_reportwrite actionFree

  Report a built period account by account: debits, credits, movement and closing balance, plus purchase commitments held as memos and the period's exceptions. Pro; ledger_lines gives the lines free.

• license_activateFree

  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.

• license_statusFree

  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.

• month_closeFree

  List what a month leaves unposted or unbalanced, with its trial balance and bank reconciliation, then store the close as a snapshot; a later call names any drift against it. dry_run writes nothing. Pro.

• period_deletewrite actionFree

  Delete one built period from the register and give its free-tier slot back. Refused when a closed month's snapshot covers the period, and that month is named. No sibling book is touched.

• trial_balanceFree

  Total the debits and the credits for a period and prove they are equal to the minor unit. When they are not, name the entries whose own legs do not add up and the source document behind each. Free and unlimited.
