    Server tool list (24)

    Raw names from tools/list. Only developers need these.

    get_catalogGet GYOTAK's full fish catalog with real-time availability, retail prices (THB/kg), freshness tiers, and traceability records. Retail prices are always included. For registered chat customers, pass customerKey (gyotak_cus_...) to show wholesale pricing and enable one-tap checkout. For LINE VIP customers, pass lineUserId. Delivery is available within Thailand only. International addresses are not accepted.
    search_fishSearch fish by name (Japanese, Thai, or English). Provide lineUserId to include VIP tier pricing.
    get_contact_infoGet the two ways to buy from GYOTAK, with the contact details for each: retail (order here through place_order, or browse the web shop) and B2B wholesale for restaurants and businesses (LINE @284ezjvm, tier pricing, application required). Call this when the user asks how to buy, how to open a wholesale account, or how to reach GYOTAK. Takes no arguments and returns static text — for product availability or prices use get_catalog, and for other questions use ask_gyotak.
    get_catch_reportsGet catch records by date or freshness tier. Returns GPS coordinates, photo timestamp, and blog URL for traceability verification. In-stock products reference these records; consumers can access records via blog URL on package label even after sold out. Planned integration: Each catch record will be registered on Midnight blockchain as an immutable on-chain transaction, making GPS coordinates, timestamps, and photo hashes tamper-proof and permanently verifiable.
    place_orderPlace an order. Two modes: (A) VIP wholesale: provide lineUserId of a registered VIP customer. (B) Guest retail: provide customerName, phone, items array, and a delivery address — shippingAddress, shippingProvince and email are all required, and an order missing any of them is rejected. Guest orders are priced at tier-linked retail rates (server-calculated) and the total is final at this point; a confirmation email with a PromptPay QR follows. If customerKey is omitted, one is issued automatically (reusing an existing chat customer with the same email) and returned in the response and the confirmation email — tell the user to save it. Inventory is NOT deducted — orders go to the pick queue for staff fulfillment. Delivery is available within Thailand only, so the province must be a Thai one. International addresses are not accepted.
    get_order_historyGet B2B order history (last 20 orders). Requires lineUserId of a registered VIP customer.
    verify_catchVerify a GYOTAK catch record DIRECTLY from the Midnight blockchain. Reads on-chain state and returns the raw hex plus decoded fields for independent verification. Unlike get_catch_reports (which returns GYOTAK's own database), this lets you verify without trusting GYOTAK. GPS coordinates are cryptographically hidden (hiding commitment with secret nonce); only the region is provable. Supports both preprod and mainnet. batchId also accepts several IDs separated by commas: they are all checked against a single fetch of the contract state, and the response lists found/not-found per ID.
    verify_tempVerify GYOTAK cold-chain storage temperatures DIRECTLY from the Midnight blockchain. Reads on-chain state and returns decoded hourly temperature records per freezer for independent verification. Unlike the dashboard (which reads from GYOTAK's D1 database), this lets you verify without trusting GYOTAK. Each value is the HOURLY AVERAGE committed on-chain; it does not prove the temperature stayed within any limit at every moment in that hour. Supports both preprod and mainnet.
    get_komon_recordsGet GYOTAK KOMON physical authentication records from the database. Each record represents a PUF (physically unclonable function) registration with minutiae extraction and on-chain commitment. Shielded records do not expose GPS.
    verify_komonVerify a GYOTAK KOMON record directly from the Midnight blockchain. Reads on-chain state and returns the raw hex plus decoded fields for independent verification. Unlike get_komon_records (which returns GYOTAK's database), this reads directly from the chain. Shielded records prove region membership without exposing GPS. Currently preprod only.
    ask_gyotakSearch GYOTAK FAQ for answers about shipping, payment, products, defrosting, traceability, B2B registration, etc. Returns top matching FAQ entries. If no match, suggest using contact_gyotak to escalate.
    contact_gyotakSubmit a question to GYOTAK staff when FAQ does not have the answer. Staff will reply via Discord. Use check_reply to retrieve the response later.
    check_replyCheck if GYOTAK staff has replied to a previously submitted inquiry.
    register_customerRegister as a GYOTAK customer. Collect name, phone, address, email, and customer type (Retail or Wholesale) via conversation BEFORE calling this tool. Returns a customerKey for future orders. Save the key in your AI memory.
    recover_customer_keyRecover a lost customerKey. For security, automatic recovery is not available — this tool guides you to contact staff.
    create_paymentCreate a Cardano tADA payment session for a pending guest order. Computes THB→tADA conversion, generates a payment session with 30-minute expiry, and returns payment details. Call this after placing a guest order to initiate payment. The payment is executed server-side using the GYOTAK A→B→A round-trip mechanism.
    check_payment_statusCheck the payment status of a guest order. Returns payment session details, amount, deadline, TX hash if paid, and current status.
    apply_referrerLook up your GYOTAK referral MCP URL. The URL is issued automatically when the payment for your first chat order is confirmed and is included in the payment confirmation email; call this to see it again. If you have a paid order but no URL yet, one is issued now. Referrers earn 5% of the product subtotal on paid orders placed through their URL. If you are connected through a personal token URL, omit customerKey.
    my_referralsShow your referral summary as a GYOTAK referrer: your referral URL, number of referred orders (paid / unpaid), this month's estimated commission, unpaid balance, payout destination status, and the last 5 paid referred orders (order number, date, subtotal, commission — no buyer details). Only works for the customer of this connection; if you are connected through a personal token URL, omit customerKey.
    get_share_kitGet the facts and constraints for writing a social media post about GYOTAK with the caller's referral URL: order facts, fish photo URLs, allowed and forbidden claims, and the required referral disclosure. The wording is up to the user and their assistant. Call this again each time the user asks for a post; do not reuse a previous result.
    report_shareReport a social media post you published that recommends GYOTAK with your referral URL. Call this right after posting, with the platform and the public URL of the post. GYOTAK records it and later verifies that the post is public and contains the referral URL.
    claim_purchase_proofClaim the on-chain purchase proofs for your own purchases and attach your X (Twitter) handle to them, so a post of yours can be checked against the chain. Only works through a personal token URL connector — there is no customerKey argument. Call with no arguments first to see which purchases can be claimed; pass handle to claim them. The handle is what you tell us: GYOTAK does not verify that you own the account.
    register_payoutEmail the GYOTAK referrer a link to the form where they register where their commission should be sent: a Thai PromptPay QR (read inside the form, the image is never uploaded) or a stablecoin address (USDC on Base, or USDM on Cardano). Call this when the user wants to register, see, or change their payout destination. Returns the destination currently on file, masked, and the masked address the link was sent to. For security the form URL is never shown in the chat — the link goes only to the email address on file, so tell the user to open it from their email. Never ask the user to type the number or the wallet address into the chat.
    confirm_paymentExecute payment for a guest order (preprod only). Requires your customerKey and a pending payment session. Triggers A→B→A round-trip settlement on Cardano preprod. Subject to monthly auto-settle allowance.
