mu_guest | The fastest way to start on MU: one call returns a guest `api_key`, a ready-made store (store slug + store_url) and free mu_credits — no email, no verification code. After this call, tell the user their api_key and have them reconnect with header `Authorization: Bearer <api_key>`; then mu_create_product works immediately. The guest key is the ONLY credential — it cannot be recovered if lost, so th params: none |
mu_register | Start MU agent registration. Emails a 6-digit verification code to the address. After receiving the code, call mu_verify with {email, code} to obtain your api_key. No authentication required for this call. params: email*, agent_name |
mu_verify | Verify the 6-digit code emailed by mu_register and receive your permanent api_key. Use that key as `Authorization: Bearer <api_key>` on all subsequent MU tool calls. No authentication required for this call. params: email*, code* |
mu_status | Get the authenticated agent's profile: email, mu_credits_balance, MA-council flag, their stores, and limits (allowed product kinds with price floors + per-hour caps). Requires `Authorization: Bearer <api_key>`. params: none |
mu_quote | Ask the MU manufacturing router how a thing could be MADE before you create a product: which supplier(s) can make it, the est. unit price (JPY), MOQ, lead time, fulfillment route, and whether it ships auto (POD, zero-inventory, order now) or needs a quote (RFQ to a factory). Pass `kind` (a known POD kind like tee/hoodie/rashguard_ls, OR a non-POD kind like `gi`/`loopwheel_sweat`/`seamless_knit`/`r params: kind, description, qty, region, budget |
mu_check | Ask the MU requirements engine whether a planned make satisfies its requirements: product spec floor (required attributes per kind), legal/compliance flags (e.g. JP 家庭用品品質表示法 / 技適 / 食品衛生法), and supplier order terms (MOQ, accepted input format, material constraints). Pass `kind` (required) + optional `region` (e.g. jp), `supplier_id`, and either `spec` (a JSON string) or individual attributes (mate params: kind*, region, supplier_id, spec, material, dimensions, colors, print_method, placement, size_range, embroidery_spec |
mu_spec_draft | Turn a natural-language request into a structured manufacturing spec (kind, material, dimensions, colors, print_method, placement, qty, region). Missing required attributes come back as `missing` with a follow-up `next_question` to fill them in. Feed the resulting spec_id into mu_rfq_create. Requires an API key (register/verify first) — uses a small amount of AI budget per call. params: prompt* |
mu_rfq_create | Open a quote request (RFQ) to a non-POD supplier (gi/loopwheel/seamless-knit/premium AOP). Generates a ready-to-send draft (subject/body) and saves it status='drafted'. Does NOT send — outbound mail/PO is a human gate. Pass `supplier_id` OR `kind`/`description` (the router resolves a quote-mode supplier), `qty`, and optionally `spec_id` (from mu_spec_draft), `product_ref`, `spec_pack_url`, `note`. params: supplier_id, kind, description, qty, spec_id, product_ref, spec_pack_url, note |
mu_rfq_record | After a factory replies, record the quote against an RFQ: set `status` (sent/received/expired) and, for received, `quoted_unit_jpy` (required) plus `moq`, `lead_time_days`, `valid_until` (ISO date). A received, still-valid quote is reflected back into mu_quote's est_unit_jpy (display only). RFQs are scoped to your account (admin sees all). params: id*, status, quoted_unit_jpy, moq, lead_time_days, valid_until, note |
mu_rfq_list | List quote requests (RFQs) with optional filters by `supplier_id`, `kind`, `status` (drafted/sent/received/expired). RFQs are scoped to your account (admin sees all). params: supplier_id, kind, status |
mu_order_create | Open a purchase order (受注) from a received RFQ (pass `rfq_id`) or directly with `supplier_id`+`kind`. If the supplier's MOQ is unmet, the order is lot-locked (lot_lock=true) until the lot (same supplier+kind) fills. Fills are public: any agent can contribute to a lot. If the deadline (30d) passes before fill, the order flips to refund_pending and is listed as an auto-refund candidate (human execut params: rfq_id, supplier_id, kind, qty, unit_jpy, note |
mu_order_advance | Move an order one step in the lifecycle: ordered→production→shipped→completed, or ordered→refund_pending (lot expiry / human judgment), refund_pending→refunded (human recorded refund). Backward/skipped transitions are rejected. Production is blocked while lot_lock=true until the lot fills. params: id*, status, note |
mu_order_status | List purchase orders with optional filters by `supplier_id`, `status`, and `refund=1` to show only auto-refund candidates (refund_pending). Orders are scoped to your account (admin sees all). params: supplier_id, status, refund |
mu_create_store | Open a new MU store (a branded storefront) under your agent account. Returns the store slug and public store_url. Requires `Authorization: Bearer <api_key>`. params: slug*, name*, emoji, color_primary, tagline |
mu_create_product | Create a product in one of your MU stores. Provide the artwork EITHER as `design_url` (an absolute https URL to ready-made art) OR as `ai_prompt` (a text brief — MU generates the artwork for you and deducts the AI-gen cost from your mu_credits balance; see mu_status → limits.ai_gen for cost_jpy and whether it is enabled). Pass exactly one of the two. `kind` must be one of: tee, tee_white, rashguar params: store*, label*, description*, kind*, design_url, ai_prompt, price_jpy, capacity, audio_url, printful_product_id, printful_variant_id, position |
mu_preview_mockup | See the mockup BEFORE creating any product — nothing is created or sold, and it costs no credits. Renders the design on the real garment (Printful) when the kind supports it (source: "printful"), otherwise a clean MU product card (source: "card"), and returns a durable preview image URL. Optionally pass `position` (front-print DTG apparel only: tee / tee_white / hoodie / crewneck / tank / long_sle params: kind, design_url, position, preview_id |
mu_affiliate | Get your personal MU affiliate (referral) link + stats. Share the `link`; when someone buys any MU product within 30 days of clicking it, you earn a commission as MU store credit (default 10% of the sale). You can also append the returned `ref_param` to any product URL. Returns clicks, sales (uses), earned_jpy and your mu_credit_balance. Requires `Authorization: Bearer <api_key>`. params: none |
mu_list_mine | List every product you have created across your MU stores: sku, store, label, kind, retail_price_jpy, status (review/live/retired/…), design_file and pdp_url. Requires `Authorization: Bearer <api_key>`. params: none |
mu_sales | Get sales for your MU stores: per-store and total order_count + revenue_jpy, plus the 50 most recent orders (sku, amount_jpy, created_at, status). Requires `Authorization: Bearer <api_key>`. params: none |
mu_upload_design | Upload a PNG design (base64-encoded, <=3MB decoded) and receive a durable https url. Pass that url as `design_url` to mu_create_product. Requires `Authorization: Bearer <api_key>`. params: data_base64*, filename |
mu_retire_product | Retire one of your products (sets status=retired, removes it from the storefront). Owner-only. Requires `Authorization: Bearer <api_key>`. params: sku* |
mu_update_product | Update one of your products. Allowed ONLY while the product is in 'review' or 'retired' (never a live product). You may change label, description, price_jpy (clamped up to the kind's floor), design_url and position (print placement; re-renders the mockup). Printful ids can never change. Owner-only. Requires `Authorization: Bearer <api_key>`. params: sku*, label, description, price_jpy, design_url, position |
mu_submit_feedback | Found a bug, or have an idea to make MU better? File it here. Use this when something on the platform/API misbehaves, a product looks wrong, or you want to request a feature. It lands in the MA-council triage queue. Requires `Authorization: Bearer <api_key>`. params: category*, title*, description*, sku, severity |
mu_ship_orders | List physical (address-bearing) orders for the factory shipping console with their ship_status (pending|in_production|shipped|delivered), courier and tracking. Owner-only: requires the store owner's `Authorization: Bearer <api_key>` (403 otherwise). params: all, reveal |
mu_ship_mark | Advance a physical order's ship_status and (when shipping) record the courier + tracking number. Owner-only. status must be one of pending|in_production|shipped|delivered. params: id*, status*, tracking, courier, notify |
mu_ship_csv | Generate a 送り状 CSV for all un-shipped orders, formatted for import into ヤマト B2クラウド (courier=yamato) or 佐川 e飛伝 (courier=sagawa). No carrier API/contract needed — import the CSV to request pickup. Returns {filename, csv_utf8 (for reading), csv_shift_jis_base64 (decode this for the actual import — B2クラウド/e飛伝 expect Shift_JIS)}. First time, register the column layout in B2クラウド. Owner-only. params: courier |
mu_gi_logos | List the MU × JiuFlow sponsored gi's 17 sponsor placements with each logo's slot, brand, position, finished size, thread color, logo file/url, status (ok=hi-res | low=low-res | request=not collected | missing), and consent (yes=written permission to embroider on apparel | requested | no). ready_to_print is true ONLY when status=ok AND consent=yes — anything else must NOT be sent to ISAMI (using a params: none |
mu_gi_logo_set | Update one gi sponsor placement (by slot from mu_gi_logos) — swap its logo_url, set its status (ok|low|request|missing) and/or add a note (e.g. where the vector was requested). Owner-only. params: slot*, logo_url, status, consent, note |
mu_ship_import_tracking | Paste the CSV that B2クラウド / e飛伝 produced AFTER issuing labels (it contains your お客様管理番号 MU-{id} plus the assigned 送り状番号). Matches each MU-{id} to the order and sets tracking + marks it shipped, in bulk. The natural counterpart to mu_ship_csv. Owner-only. params: csv*, courier |
mu_ship_order | Fetch a single physical order by id with its status, courier and tracking. Address/phone are masked unless reveal=true. Owner-only. params: id*, reveal |
mu_gi_request_logos | For every gi sponsor whose consent is not yes, generate a ready-to-send draft asking for (1) written permission to embroider their mark on the gi and (2) the vector logo. Does NOT send (outbound mail is a human gate). When a brand grants permission, record it with mu_gi_logo_set consent:yes. Owner-only. params: none |
mu_gi_techpack | Return the MU × JiuFlow gi's public page and lifestyle/mockup image URLs (front/back/crest/QR). The dimensioned tech-pack PDF lives in the repo (docs/gi-isami-2026-05-12/). Owner-only. params: none |
