What it can do
| Tool | What it says it does |
|---|---|
accept_autopost_decision | One-click accept of a **held** decision (accountant) — posts the AI's proposal. A person's accept overrides the soft guardrails. An agent's is refused (403) unless the row is ``agent_acceptable`` or an expense receipt. Closed period, sealed year, unknown account: 409/422. The row flips ``held →… |
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 exactly what… |
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 tell you when they… |
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 justified it… |
customer_statement | One customer's open items + totals (the aging row's drill-down). ``as_of`` mirrors ``GET …/ar/aging`` — set, it reconstructs the items open at that date so the statement agrees with a historical aging report. |
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/list`` publishes no… |
entry_candidates | Entry Candidates |
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 — are available but… |
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`` → ``cancelled``)… |
get_bank_entry | Get Bank Entry |
get_bank_status | Composed bank snapshot — "is my banking up to date?" (CompanyMember). "Reconciled" means entries matched, NOT ledger = statement balance (the close check ``BANK_BALANCE_DOES_NOT_TIE_OUT`` compares that). Per-account entry-status and ``in_suspense`` counts, each account's latest closing balance… |
get_company | Get one company (jwt, scoped). 403 for a non-member non-admin, 404 if absent. |
get_financial_statements | Computed balance sheet + P&L for a fiscal year, from the journal (CompanyMember). Aggregates every posted GL journal line whose **posting date** falls in the fiscal year's window, classifies each account against the chart of accounts, and reports problems (unbalanced trial balance, unclassified… |
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 are included (a… |
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 % line is… |
get_intake | Get one intake row by id (scoped to its company: 404/403 split). |
get_item | Item metadata (any source). |
get_work_list | Everything waiting for this user in this company, most severe first. |
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-counts silently… |
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). |
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"}``. |
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 entry with no… |
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_number`` — the chart… |
list_bank_entries | List Bank Entries |
list_companies | List companies (jwt, scoped). Non-admins see only their member companies. |
list_counterparties | List a company's counterparties (filter by ``kind``/``q``, paginated). ``kind`` repeats to filter on a set (``?kind=customer&kind=both``) — a role-shaped picker asks for every kind that plays the role. A single ``?kind=supplier`` keeps its original meaning. |
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). |
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 the route lists every fiscal year. ``total`` is the filtered total. ``untagged_subledger_control=true`` narrows to the entries… |
list_gl_open_items | One page of the AR/AP subledger (member read). ``direction`` filters server-side (ZCT-577) — omit it for both. ``commercial_document_id`` narrows to one document's item (D09-G13); not with ``as_of``. ``as_of`` (ZCT-577) reconstructs each item's open amount from posted journal lines dated on or… |
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`` still accepts them… |
list_gl_vat_periods | List Gl Vat Periods |
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… |
onboarding_guide | How to onboard and create a NEW company: what to ask the user for, which documents to request, and the order to run the setup in. Discovery does not depend on search: this tool is in the tier, so it is listed for every caller, and `BASE_INSTRUCTIONS` names it. `find_operations` does reach… |
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-account``, which… |
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 signed in as the owner… |
reverse_gl_journal_entry | **Storno** a posted journal entry: post its mirror image (accountant role). Nothing is deleted; the original stays, linked, and the **reversal** entry is returned. The only VAT-correct storno door — VAT postings, open items and what the document spawned are all unwound. ``body.posting_date``… |
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 native settlement… |
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 `client_name`… |
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-only: it never… |
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 statements (CAMT.053 XML… |
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_scoped: true``… |
zeno_info | What this server is, which MCP revision it speaks, and how to get a credential. **Needs no credential.** Call it first if a tool has just refused you: the `authentication` block names the tools that can get this session connected. |
zeno_overview | What Zeno does, in one page — the platform's capabilities and its limits. **Needs no credential.** Read this before telling a user that Zeno cannot do something; it covers VAT, payroll, reconciliation and the AI accountant. |
