Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Dumps the whole environment servers/office-suite/src/index.ts:125

  for (const [k, v] of Object.entries(process.env)) if (v !== undefined) env[k] = v;

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 9

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ledger

ledger_build

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_csv

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_lines

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_report

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

license_activate

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_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.

month

month_close

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

period_delete

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

trial_balance

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.

Cash Book — questions

Answers built from our own checks of this server.

What can Cash Book do?

It exposes 9 tools, read directly from the server on our last check. Among them: ledger_build, ledger_export_csv, ledger_lines, ledger_report, license_activate, license_status and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Cash Book mostly used for?

Its tools cluster around ledger and license. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Cash Book working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 87 of 87 checks got a reply (100.0%), average response time 242 ms. The bar chart above shows every period we have measured.

How do I connect Cash Book?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Cash Book need an API key?

No. Cash Book completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Cash Book?

It answers our handshake in 242 ms on average, which is faster than 62% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Cash Book open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 2 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.zovo.one, which runs on its operator's own terms.
