apideck-mcp-month-end-close

apideck-mcp-month-end-close is a skill for Claude Code from apideck-libraries/api-skills. It costs 86 tokens per session (1,307 once invoked), scanned A, original, Apache-2.0.

A read-only month-end accounting snapshot workflow using the Apideck MCP server. It combines profit and loss, balance sheet, aged creditors, and aged debtors reports when available.

In plain words
What is it for?
Use it for a month-end close view or financial reports as of a specific date; bank-statement reconciliation is outside its scope.
Why use it?
It avoids collecting these financial reports one by one and can still return a partial snapshot when a connected accounting system lacks some reports.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

apideck-mcp-month-end-close scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Month-end close snapshot (Apideck MCP)

When the user wants a one-shot financial snapshot, prefer apideck-month-end-close-check over fetching the four reports individually. The workflow fans out aged creditors, aged debtors, balance sheet, and profit-and-loss in parallel against the connected accounting service and returns one aggregated object.

When this is the right tool

User intent Tool
"Run the month-end close", "P&L plus balance sheet for last month", "Aged AP/AR snapshot as of March 31" apideck-month-end-close-check
"Just the P&L" accounting-profit-and-loss-get directly
"Just aged creditors" accounting-aged-creditors-get directly
"Reconcile bank statements" Out of scope — use the connector's native reconciliation

IMPORTANT RULES

  • READ-ONLY, idempotent. Safe to call repeatedly — no confirmation needed. The tool fetches data; it doesn't post anything.
  • OMIT report_as_of_date to use today. Most users running a month-end ask for "last month", in which case pass an explicit YYYY-MM-DD like "2026-03-31".
  • EXPECT partial results. Connector coverage varies — Odoo doesn't implement aged-creditors, Moneybird doesn't implement balance-sheet, etc. The workflow returns { unsupported: true, reason } for steps the connector can't fulfill, plus a top-level warnings[] array. Surface these to the user instead of treating them as failures.
  • isError: true only fires when every report failed — typically a missing connection or expired credentials. Partial snapshots come back as isError: false so the agent can still extract value.

Argument map

Arg Required Default Notes
report_as_of_date no today (YYYY-MM-DD) Cutoff date for aged reports + balance sheet.
x-apideck-service-id no first accounting connection E.g. "xero", "quickbooks".

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
