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.

Tools (16)

check_availabilityread-onlyCheck whether a new request can be taken now. Remote work (calls, online reservations) has a daily limit; on-the-ground work takes one job at a time. Returns open or full and when it reopens.
check_invoiceread-onlyCheck whether a Japanese corporation is a registered Qualified Invoice Issuer (needed for consumption-tax credit). Accepts T + 13 digits or the 13-digit corporate number.
check_openread-onlyCheck whether a MARU Order restaurant is taking takeout orders now, its hours and whether it accepts JPYC with a discount.
get_company_profileread-onlyOne profile for a Japanese corporation from its 13-digit corporate number: registered name and address, invoice (tax) registration status, and listing, industry and capital if it files with EDINET.
get_menuread-onlyGet a MARU Order restaurant's menu: categories, items with tax-included JPY prices, options (size, toppings), allergens and sold-out flags. Use list shop slugs from the maru://order/shops resource.
get_request_statusread-onlyGet the status of a request: received, quoted (price and how to pay), paid, in_progress, done (with result), cancelled or refunded.
hub_list_providersread-onlyList the third-party services listed on Ask Japan and the tool prefix each one uses.
hub_register_providerFor service providers: list your public remote MCP server (Streamable HTTP, HTTPS) on Ask Japan so its tools become available to every AI that connects to Ask Japan. The check is automatic: the URL must be public HTTPS, tools/list must work, and tool text must not contain instructions aimed at the AI. Returns approved or rejected with the reason.
list_servicesread-onlyList the services MARU Japan Hands provides in Japan (Japanese phone calls, restaurant and golf reservations, shopping proxy, on-site checks, interpreting, Osaka stays, home search and property viewings, app development), with prices in JPY, limits and what is not offered.
lookup_postcoderead-onlyGet the address for a 7-digit Japanese postcode, including large offices that have their own postcode.
place_takeout_orderPlace a takeout order. Returns an order number and a link. The customer pays at pickup at the counter, or opens the link to pay with JPYC (discounted). This tool never charges or moves money.
quote_purchaseread-onlyInstant cost estimate to buy an item sold in Japan and ship it: item price (from the shop page the user or agent found), our fee (10%, minimum JPY 2,000) and shipping estimated from Japan Post's official EMS table. Read-only: it does not order or charge anything.
request_serviceSend a request for a service in Japan. Fixed-price services (phone_call JPY 1,500, restaurant_booking JPY 3,000, interpreting JPY 5,000 per 30 min) return the quote and payment details immediately. Other services get a fixed quote from a person within 2 hours (JST 09:00-21:00); requests sent outside hours are handled from 09:00. No email is needed: follow up with get_request_status. Creating a request is free and does not move any money. Full refund if we cannot do the task or you cancel before work starts.
search_addressread-onlyFind postcodes by part of a Japanese address or an office name, e.g. 大阪市北区梅田.
search_companyread-onlySearch all ~5.8 million corporations registered in Japan by name (Japanese, partial match). Returns corporate number, address, type and whether it is closed. Use the corporate number with get_company_profile.
search_listed_companiesread-onlyFilter companies that file securities reports in Japan (EDINET) by industry (Japanese name, e.g. 不動産業, 輸送用機器) and minimum capital. Returns securities code and capital.
