Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

lookup_zipcode 郵便番号から住所を逆引きする。100-0005 または 1000005 形式に対応(全角数字・ハイフン有無は不問)。結果には日本郵便準拠のローマ字表記(romaji)を含む。 / Reverse lookup: get the Japanese address for a postal code. Accepts 100-0005 or 1000005 (full-width digits and missing hyphens are fine). Results include Japan Post romaji.

search_address 日本の住所文字列から郵便番号を検索する。番地・建物名付きでも町名まで解釈する。ローマ字・英語表記(例: Marunouchi, Chiyoda-ku, Tokyo)でも検索可。結果には日本郵便準拠のローマ字表記(romaji)を含む。 / Look up a Japanese postal code from an address string. Tolerates messy input (full-width digits, hyphen variants, street numbers and building names) and resolves down to the town level. Romaji/English input is accepted. Results include Japan Post romaji.
