Tools
| Tool | Description | Behaviour |
|---|---|---|
| apply_referrer | Look 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. | Not declared |
| ask_gyotak | Search 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. | Not declared |
| check_payment_status | Test / QA only — do not use for customer orders. Returns the Cardano preprod payment session of an order placed by a GYOTAK test customer (status, amount, deadline, TX hash if paid). For any other order_id it returns PromptPay guidance and nothing about the order. Customers pay via the PromptPay QR attached to the order confirmation email and receive an email once the payment is confirmed. | Not declared |
| check_reply | Check if GYOTAK staff has replied to a previously submitted inquiry. | Not declared |
| claim_purchase_proof | Link your own purchases’ on-chain purchase proofs to your X (Twitter) account, so a post of yours can be checked against the chain. Buyer’s X account (self-declared): the buyer linked this purchase to their own X account; GYOTAK has not checked that the account belongs to the buyer. Each stamped purchase comes with the URL of its public verification page. Only works through a personal token URL connector — there is no customerKey argument. Called with no arguments it only lists the purchases that can be linked and links nothing, every time — pass handle to actually link. A link is stamped on chain and cannot be undone, so let the user pick the handle before you pass one. Automatic binding of future purchases is off by default: to turn it on, pass handle with auto_bind "on" — the first such call returns the consent text; show it to the user word for word (the text is in Japanese and English; show both), and only if they agree call again with consent true. Pass auto_bind "off" to stop it (no handle needed); only later purchases stop, anything already recorded stays. | Not declared |
| confirm_payment | Test / QA only — do not use for customer orders: customers pay via the PromptPay QR attached to the order confirmation email. Executes the Cardano preprod A→B→A settlement for an order placed by a GYOTAK test customer. Requires that test customer's customerKey, a pending payment session from create_payment, and a monthly auto-settle allowance. For any other order_id it returns PromptPay guidance and changes nothing. | Not declared |
| contact_gyotak | Submit 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. | Not declared |
| create_payment | Test / QA only — do not use for customer orders, and do not call it after placing a customer order: customers pay via the PromptPay QR attached to the order confirmation email. Works only for orders of GYOTAK test customers; for any other order_id it returns PromptPay guidance and creates nothing. For a test order it computes the THB→tADA conversion, creates a Cardano preprod payment session with a 30-minute expiry, and returns the payment details (GYOTAK A→B→A round-trip). | Not declared |
| get_catalog | Get 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. | Not declared |
| get_catch_reports | Get catch records by date or freshness tier. Returns the catch date, the region (district name), the blog post URL when published and, for records registered on the Midnight blockchain, a verify link per batch. Exact GPS coordinates are never returned: on v3 records the exact position is not on the chain (only a commitment to it); the record carries a zero-knowledge proof that the position lies within a range, and the district name is a label set by GYOTAK that is not part of that proof. In-stock products reference these records by date. To check a record on-chain without trusting GYOTAK, open its verify link, or call verify_catch with network "mainnet", the v3 contract address given in the response and the batch ID. | Not declared |
| get_contact_info | Get 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. | Not declared |
| get_komon_records | Get 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. | Not declared |
| get_order_history | Get B2B order history (last 20 orders). Requires lineUserId of a registered VIP customer. | Not declared |
| get_share_kit | Get the facts and constraints for writing a social media post about GYOTAK with the caller's referral URL: order facts, fish photo URLs, verification page URLs of the caller's stamped purchase proofs, 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. | Not declared |
| my_referrals | Show 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. | Not declared |
| place_order | Place 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. Without customerKey or a personal token URL connection, every order creates a new customer with a new customerKey, even when the email was used before (orders are never linked to an existing customer by email); the new key is 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. | Not declared |
| recover_customer_key | Explains where a lost customerKey can be found: a key issued with an order is written in the order confirmation email sent to the registered address (each order placed without a key has its own key). For keys that cannot be found there, it points to contact_gyotak. This tool does not look up, verify or send anything. | Not declared |
| register_customer | Register 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. | Not declared |
| register_payout | Email 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. | Not declared |
| report_share | Report 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. | Not declared |
| search_fish | Search fish by name (Japanese, Thai, or English). Provide lineUserId to include VIP tier pricing. | Not declared |
| verify_catch | Verify 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 (GYOTAK's own list of records: date, district and verify links, never GPS), this lets you verify without trusting GYOTAK. The exact position is not on the chain (only a commitment to it). The record carries a zero-knowledge proof that the position lies within a range. The region name is a label set by GYOTAK; the range used in the proof is not part of the record. 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. | Not declared |
| verify_komon | Verify 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. | Not declared |
| verify_temp | Verify 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. | Not declared |
