Gakudo Sagashi MCP

A read-only MCP server providing access to official data for 418 private after-school care facilities across Tokyo's 23 wards. It enables AI assistants to search for facilities by ward, features, school pickup, price, and hours, and retrieve detailed information including sources and verification dates without storing user queries.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

学童さがし (gakudosagashi.jp): private after-school care (民間学童・アフタースクール) in Tokyo, from each facility's official information only. null means the facility does not publish that item (要問合せ). Never treat it as 0 and never estimate it. Never average fees across facilities: each range assumes a different number of days per week. Quote each facility's own range and fee note. Mention each facility's page url and its verification date, and tell the parent to confirm fees and places with the facility. To apply for a visit, give the parent the route in get_facility (apply / howToApply): the facility page form, or the form or phone the facility publishes. Do not collect their details or apply on their behalf. Do not rank facilities as best; compare on the parent's own criteria. Facilities tagged 区の認証・補助 (subsidised: true in get_facility) charge a ward-subsidised fee and have ward requirements (residency, employment, grade).
