## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-09-26.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 1 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 79/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 581 tokens (~116/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (5)

### `screen_journals` (~247 tokens)

仕訳データに全ルールを適用し、リスクスコアの高い順に並べ替えて返す。先に人間が見るべき束を絞り込むための一次スクリーニング。検出は不正の証拠ではない。

Input parameters:

- `journals` (array, required): 仕訳の配列。簡易形 { date, debit_account, credit_account, amount } か、明細形 { date, lines: [{ account, debit, credit }] } のどちらでも受ける。
- `options` (object): スクリーニングの前提条件。監査対象の実態に合わせて渡す。
- `skipInvalid` (boolean): 読めない仕訳（日付の形式違い・負の金額など）を除外して続ける。既定は false で、1件でも読めなければ全体を止める。除外した行は invalidRows に返す。
- `top` (number): 上位何件を返すか。既定は 50。

### `check_balance` (~165 tokens)

貸借が一致しない仕訳だけを返す。取込不良と手入力の混入を最初に落とすために使う。

Input parameters:

- `journals` (array, required): 仕訳の配列。簡易形 { date, debit_account, credit_account, amount } か、明細形 { date, lines: [{ account, debit, credit }] } のどちらでも受ける。
- `skipInvalid` (boolean): 読めない仕訳（日付の形式違い・負の金額など）を除外して続ける。既定は false で、1件でも読めなければ全体を止める。除外した行は invalidRows に返す。

### `benford_analysis` (~236 tokens)

金額の先頭桁の分布をベンフォードの法則と比較し、MAD と χ² を返す。母集団の性質を見るための道具で、個別仕訳の判定には使えない。

Input parameters:

- `amounts` (array): journals の代わりに金額だけを渡す場合。
- `digits` (number): 1 = 先頭1桁、2 = 先頭2桁。既定は 1。
- `journals` (array): 仕訳の配列。簡易形 { date, debit_account, credit_account, amount } か、明細形 { date, lines: [{ account, debit, credit }] } のどちらでも受ける。
- `skipInvalid` (boolean): 読めない仕訳（日付の形式違い・負の金額など）を除外して続ける。既定は false で、1件でも読めなければ全体を止める。除外した行は invalidRows に返す。

### `detect_duplicates` (~174 tokens)

計上日・金額・借方科目・貸方科目が完全に一致する仕訳をグループにして返す。明細の行の順番は問わない。

Input parameters:

- `journals` (array, required): 仕訳の配列。簡易形 { date, debit_account, credit_account, amount } か、明細形 { date, lines: [{ account, debit, credit }] } のどちらでも受ける。
- `skipInvalid` (boolean): 読めない仕訳（日付の形式違い・負の金額など）を除外して続ける。既定は false で、1件でも読めなければ全体を止める。除外した行は invalidRows に返す。

### `list_rules` (~39 tokens)

実装されているスクリーニングルールの一覧と、それぞれが何を示すかの説明を返す。
