## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-21.

- **Endpoint Security**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 84/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1148 tokens (~104/item across 11 items; 9 tools + 2 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (9)

### `ledger_build` (~112 tokens)

Build the ledger for a period

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.

Input parameters:

- `currency` (string): Needed when the period holds documents in more than one currency. Currencies are never added together
- `from` (string, required): First day of the period, YYYY-MM-DD
- `to` (string, required): Last day of the period, YYYY-MM-DD, inclusive

### `period_delete` (~101 tokens)

Delete a built period

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.

Input parameters:

- `currency` (string): Needed only when the same date range was built in more than one currency
- `from` (string, required): First day of the period, YYYY-MM-DD
- `to` (string, required): Last day of the period, YYYY-MM-DD, inclusive

### `trial_balance` (~113 tokens)

Prove the ledger balances

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.

Input parameters:

- `currency` (string): Needed when the period holds documents in more than one currency. Currencies are never added together
- `from` (string, required): First day of the period, YYYY-MM-DD
- `to` (string, required): Last day of the period, YYYY-MM-DD, inclusive

### `ledger_lines` (~252 tokens)

List 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.

Input parameters:

- `account` (string): Only this account, e.g. cash, receivables, vat_output, or a category prefix such as "expenses"
- `currency` (string): Needed when the period holds documents in more than one currency. Currencies are never added together
- `from` (string, required): First day of the period, YYYY-MM-DD
- `limit` (integer): Maximum rows, default and ceiling 5000
- `since` (string): Only lines dated on or after this date, YYYY-MM-DD
- `source` (string): Only lines derived from this server: invoice, billing-docs, deposits, expense-tracker or asset-register
- `source_id` (string): Only lines derived from this document, e.g. INV-2026-0001
- `to` (string, required): Last day of the period, YYYY-MM-DD, inclusive
- `until` (string): Only lines dated on or before this date, YYYY-MM-DD

### `month_close` (~112 tokens)

Close a month

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.

Input parameters:

- `currency` (string): Needed when the period holds documents in more than one currency. Currencies are never added together
- `dry_run` (boolean): Report the exceptions and the trial balance without writing the close. Default false
- `month` (string, required): The month to close, YYYY-MM

### `ledger_export_csv` (~143 tokens)

Export the ledger as 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.

Input parameters:

- `account` (string): Only this account or category prefix
- `currency` (string): Needed when the period holds documents in more than one currency. Currencies are never added together
- `from` (string, required): First day of the period, YYYY-MM-DD
- `source` (string): Only lines derived from this server
- `to` (string, required): Last day of the period, YYYY-MM-DD, inclusive

### `ledger_report` (~107 tokens)

Report movement and balance per account

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.

Input parameters:

- `currency` (string): Needed when the period holds documents in more than one currency. Currencies are never added together
- `from` (string, required): First day of the period, YYYY-MM-DD
- `to` (string, required): Last day of the period, YYYY-MM-DD, inclusive

### `license_status` (~55 tokens)

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.

### `license_activate` (~76 tokens)

Activate license

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.

Input parameters:

- `key` (string, required): License key from checkout, MCPL1.<payload>.<signature>

### Is the io.github.theluckystrike/cash-book MCP server safe to use?

io.github.theluckystrike/cash-book scores 84 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.theluckystrike/cash-book MCP server expose?

io.github.theluckystrike/cash-book exposes 9 tools: ledger_build, period_delete, trial_balance, ledger_lines, month_close, and 4 more. Their descriptions and schemas cost roughly 1,071 tokens of context every time the server is loaded.

### Does the io.github.theluckystrike/cash-book MCP server require authentication?

Yes. io.github.theluckystrike/cash-book asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
