Parameters1

tool

string

required

スキーマを取得する MCP ツール名（例: data.validate_json）

  "type": "object",
  "properties": {

No parameters.

Raw schema

data.execute_batch

[data] 【複数ツール連続の前に検討】tools:[{id,tool,args}] で MCP ツールを最大10件順次実行。{{stepId.field}} で前ステップ結果を参照。関連ツール3〜5本を個別呼び出しすると往復3〜5回＋ツール呼び出しオーバーヘッドが重複するが、execute_batch で1回にまとめコンテキスト消費を大幅削減（概算）。Examples: (1) 今日の日時→祝日→為替 tools:[{id:now,tool:datetime.get_current_datetime,args:{timezone:Asia/Tokyo}},{id:holiday,tool:datetime.is_holiday,args:{country:JP,date:{{now.date}}}},{id:rate,tool:network.get_exchange_rate,args:{from:USD,to:JPY}}] (2) JSON検証→マージ→統計 tools:[validate:data.validate_json,merge:data.merge_json,stats:data.calc_stats] (3) スラッグ→Base64→HMAC tools:[slug:text.generate_slug,b64:convert.base64,hmac:security.generate_hmac]。詳細は tool-catalog の execute_batch_presets 参照 / Prefer before chaining MCP tools: run up to 10 tools via tools:[{id,tool,args}] with {{stepId.field}} refs. Calling 3-5 related tools individually costs ~3-5 round trips plus repeated tool-call overhead; execute_batch combines them into one call, cutting context usage significantly (approx.). Ex1 today→holiday→rate: tools:[{id:now,tool:datetime.get_current_datetime,args:{timezone:Asia/Tokyo}},{id:holiday,tool:datetime.is_holiday,args:{country:JP,date:{{now.date}}}},{id:rate,tool:network.get_exchange_rate,args:{from:USD,to:JPY}}]. Ex2 validate JSON→merge→stats. Ex3 slug→base64→HMAC. See execute_batch_presets in the tool-catalog MCP Resource. [use_cases: workflow, batch]

text.mask_pii

[text] テキスト内の個人情報（メール・日本の電話番号・クレジットカード）を正規表現＋Luhnで検出してマスキング。固定長マスクで元の長さを漏らさない。正規表現ベースのため偽陽性/偽陰性あり（専用DLPの代替ではない） / Detects and masks PII (email addresses, Japanese phone numbers, credit card numbers) in text using regex + Luhn validation for cards. Uses fixed-length masking (not length-preserving) so masked output doesn't leak the original length. Note: regex-based detection has inherent false-positive/false-negative tradeoffs — not a substitute for a dedicated DLP solution. [use_cases: security, text_processing]

Parameters3

text	string	required	Text to scan and mask (max 50,000 characters)
types	array	optional	PII types to detect. Defaults to all of email, phone_jp, and credit_card when omitted.
mask_char	string	optional	Single character used for masking (default "*"). Must be exactly one character (surrogate pairs are not allowed).

data.diff_arrays

[data] 2つの配列を比較し added / removed / unchanged を返す（プリミティブ配列・key指定オブジェクト配列・順序無視比較） / Compares two arrays and returns added, removed, and unchanged elements. [use_cases: data_extraction, workflow]

Parameters4

before	array	required	Source array to compare from
after	array	required	Target array to compare to
key	string	optional	Object key field for ID-based comparison (omit for primitive arrays)
ignore_order	boolean	optional	Compare as sets ignoring element order (default false)

data.sort_json

[data] JSONオブジェクト配列を複数キー・昇順/降順混在で安定ソート（ドット記法のネストキー対応・欠損/null/型不一致は末尾） / Sorts an array of JSON objects by one or more keys, with independent ascending/descending order per key. Uses a stable sort, so LLMs no longer need to hand-write multi-key comparator logic (a common source of bugs). [use_cases: data_processing, workflow]

Parameters2

items	array	required	Array of JSON objects to sort (max 1000 elements)
sort_keys	array	required	Sort keys evaluated in order; earlier keys take precedence, later keys break ties
