51 tools

• find_operations

  Search EVERY operation this server offers, including the ones not in your tool list. The tool list you can see holds only the common operations. Several hundred more — payroll, VAT returns, year-end close, fixed assets, expenses, cash book, settings, integrations, onboarding — a

• describe_operations

  Get the full argument schema for operations found via ``find_operations``. Returns each operation's description and JSON-Schema arguments — everything a listed tool would have shown you. ``include_output_schema`` is the ONLY way to obtain an operation's result shape: ``tools/li

• call_operation

  Run any operation by name — the ones in your tool list and the unlisted ones alike. ``name`` is an operation name from ``find_operations``; ``arguments`` is the object described by ``describe_operations`` (omit it for an operation that takes none). The result, and any error, are

• request_api_key

  Ask the user to hand this session a Zeno API key. **Use this first** — every current Zeno user already has an account. `email` is the address on their Zeno account. **Ask them for it**; you cannot guess it, and the request is aimed by it — Zeno will only show it to somebody sign

• start_signup

  Create a Zeno account for somebody who does not have one yet. Use `request_api_key` first if they might already have an account — this tool cannot tell you, and deliberately never will. We email `email` a verification link. The user opens it, sees that you asked (by the name in

• collect_api_key

  Collect the key once the user has approved. `status` is one of: - `pending` — nobody has approved yet, or (with `throttled: true`) we were rate-limited and learned nothing. **Wait `poll_interval_seconds`, then call again** — every answer carries it. Do not ask the user to t

• whoami

  Which user this request acts as, and which company's books it is bound to (jwt or API key). Zeno serves every tenant from one host, and an API key is opaque — nothing else tells a connected agent whose books it is about to write. Call this FIRST when working over MCP: ``company_

• list_companies

  List companies (jwt, scoped). Non-admins see only their member companies.

• get_company

  Get one company (jwt, scoped). 403 for a non-member non-admin, 404 if absent.

• global_search

  Full-text search across emails + items, ranked by ``ts_rank_cd``, scoped (A1). ``archive_status`` constrains item results only (the Documents → Archive page passes ``archived`` so its search box never surfaces pending/triage-parked items).

• get_kpi_report

  Snapshot KPIs + 13-week liquidity forecast, from the GL (CompanyMember). Cash/liability balances aggregate the FY window of posted/reversed journal lines; aging + forecast read ``gl_open_item``, pending salary batches and unpaid VAT periods. Read-only. Explicit non-member ``comp

• get_work_list

  Everything waiting for this user in this company, most severe first.

• list_autopost_decisions

  Recent AI-accountant autonomy decisions (CompanyMember) — the activity feed. Shows what the autonomy policy posted (``posted``), would have posted in ``assist`` shadow mode (``shadow``), or held for human review (``held``). ``ai_no_match`` shadow rows (one per AI-consulted bank

• accept_autopost_decision

  One-click accept of a **held** decision (accountant) — posts the AI's proposal. The accepting actor's approval replaces every soft guardrail (confidence, amount cap, risk flags); hard blocks stay enforced by the posting path (closed period / sealed FY / unresolvable accounts → 4

• upload_intake

  Upload ANY file and let the system decide what it is (the unified intake queue — the same door as "Documents → Upload" in the web app). ``file_base64`` is the file's raw bytes, base64-encoded. Prefer this whenever the file is not plainly an invoice, and always for: bank statemen

• upload_document

  Upload an INVOICE or RECEIPT (PDF, image, or .zip of them) for analysis. ``file_base64`` is the file's raw bytes, base64-encoded. ``direction`` is ``payable`` (incoming supplier invoice) or ``receivable`` (outgoing). Creates Item(s) and queues extraction. This door is invoices-o

• get_intake

  Get one intake row by id (scoped to its company: 404/403 split).

• list_items

  List/filter items, scoped to the caller's member companies (A1). Optional ``period`` (``YYYY-MM``) filters by the item's effective date (invoice date, falling back to the Europe/Zurich-local ingestion date); a malformed value returns 422 ``{"msg": "period must be YYYY-MM"}``. ``

• get_item

  Item metadata (any source).

• gl_trial_balance

  Per-account debit/credit columns for one fiscal year, with totals. ``fiscal_year`` (year label) defaults to the latest year posted in; ``period_id`` narrows to one period of it. No all-years mode — account identity is ``(company, fiscal year, code)``, so aggregating double-count

• gl_profit_and_loss

  Revenue − expense → net result, for one fiscal year. **Window** — same rules as the trial balance: ``fiscal_year`` defaults to the latest posted year, ``period_id`` narrows to one period of it, unknown values are 404 and a contradictory pair 422. A P&L is a **flow** statement, s

• gl_balance_sheet

  Assets vs liabilities + equity for one fiscal year, signed by natural side. Window rules as the trial balance (``fiscal_year`` defaults to the latest posted year; no all-years mode, ZET-155). With ``period_id`` this is a *movements* aggregate over that period, not a position. ⚠

• list_gl_accounts

  List the postable chart (CompanyMember). ``fiscal_year`` filters to one year's chart (the chart is FY-scoped, so codes repeat across years).

• get_gl_account_ledger

  One account's ledger (Kontoauszug) — every booking that touched it, in date order, with Soll/Haben and the running balance after each line (CompanyMember). No fiscal-year parameter: the chart is FY-owned, so ``account_id`` already fixes the year. Posted **and** reversed entries

• list_gl_periods

  The company's **accounting periods** — the months a journal entry may post into (CompanyMember read). A period belongs to one fiscal year and carries ``period_no`` (1..12 within the year), ``date_from``/``date_to`` and a ``status``: ``open`` accepts postings, ``soft_closed`` sti

• list_gl_open_items

  One page of the AR/AP subledger (member read). ``direction`` filters server-side (ZCT-577) — omit it for both. The screen used to filter the fetched page in the browser, which made the AR chip drop rows and the total count both directions. ``as_of`` (ZCT-577) reconstructs each

• list_gl_journal_entries

  List journal entries. ``period_ids`` narrows to specific fiscal periods, and is how a caller asks for **one fiscal year** — the year's period ids (ZET-285). Without it this route listed, and counted, every fiscal year the company has: the Journal page cut the year out of the fet

• get_gl_journal_entry

  One entry + lines, plus the subledger rows it produced/touched (Gap B detail surfacing): its ``gl_vat_posting`` rows, its ``gl_vat_zero_posting`` turnover-only declarations (zero-rated/exempt output — R2-13b: these have no VAT line to pair, so without them a correctly coded 0 % l

• create_gl_journal_entry

  Create a **draft** journal entry by hand — accountant. It carries NO source document unless you name one. Only the pipeline paths stamp ``source_ref_type``/``source_ref_id`` (an ingested document is ``'item'``), so by default a booking made here cannot be traced back to what jus

• post_gl_journal_entry

  Post a draft entry into the books — accountant. One-way. A posted entry can no longer be replaced or discarded (both refuse with 409); the only general correction is ``…/reverse``, which leaves both the original and the reversal visible. The one exception is ``PUT …/guessed-acco

• reverse_gl_journal_entry

  **Storno** a posted journal entry: post its mirror image (accountant role). Nothing is deleted; the original stays, linked both ways, and the **reversal** entry is returned. The only VAT-correct storno door — VAT postings, open items and what the document spawned are all unwound

• list_bank_accounts

  The company's bank accounts — the ``bank_account_id`` every statement import, bank-entry list and reconciliation call needs (CompanyMember read). Oldest first, no filter and no paging. Each row carries the ``iban``, ``currency``, ``label``/``bank_name`` and ``ledger_account_numb

• list_bank_entries

  List Bank Entries

• get_bank_entry

  Get Bank Entry

• entry_candidates

  Entry Candidates

• settle_entry

  Post this reconciled bank entry into the GL (clean-bank settlement). Matched → Dr Bank / Cr AR; unmatched → Dr Bank / Cr Suspense; a previously-suspensed entry now fully matched → Dr Suspense / Cr AR. Idempotent, and a no-op (``skipped``) when the GL chart is not configured for

• reconciliation_summary

  Reconciliation summary banner. Optional ``from``/``to`` scope the **per-entry bank-entry counts** (total / matched / missing-invoice / …) to a ``booking_date`` window — mirroring the ``/bank-entries`` grid filter — so the banner agrees with a month-filtered table. The cross-mont

• list_ar_invoices

  List authored AR invoices, newest first. Optional ``status`` / ``doc_type`` filter by lifecycle + document kind. Optional ``period`` (``YYYY-MM``) filters by the invoice's issue date (its month); a malformed value returns 422 ``{"msg": "period must be YYYY-MM"}``.

• get_ar_invoice

  One authored outgoing invoice with its lines (CompanyMember read). Carries the header (customer, dates, currency, discounts), every line with its computed ``net_amount``/``vat_amount``/``gross_amount``, the document totals, and the lifecycle: ``status`` (``draft`` → ``issued`` →

• create_ar_invoice

  Create an outgoing (sales) invoice as a **draft** — nothing is booked yet (accountant role). A draft changes no ledger balance, gets no invoice number and appears in no VAT return; it exists so it can be edited. Posting happens later, at ``POST …/ar/invoices/{invoice_id}/issue``
