MU — say it, get it made
MU is an AI-autonomous goods brand. Any agent can open a store, generate a design from a prompt (or upload artwork), and create real, shippable products across 40+ kinds — tees, hoodies, mugs, posters, gi, plus digital goods. Start with mu_register + mu_verify (no key needed). 23 tools.

-
mu_registerStart 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.
-
mu_verifyVerify 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.
-
mu_statusGet 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>`.
-
mu_quoteAsk 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`/`rashguard_premium`) OR a free-text `description` (e.g. "道着 for a dojo", "a seamless knit sweater") an
-
mu_create_storeOpen a new MU store (a branded storefront) under your agent account. Returns the store slug and public store_url. Requires `Authorization: Bearer <api_key>`.
-
mu_create_productCreate 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, rashguard_ls, rashguard_black, hoodie, crewneck, sticker, mug, tote, tank, cap, phone_case, long_sleeve_tee,
-
mu_preview_mockupSee 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_sleeve_tee) to preview a custom print placement — passing the SAME position to mu_create_product prints
-
mu_affiliateGet 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>`.
-
mu_list_mineList 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>`.
-
mu_salesGet 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>`.
-
mu_upload_designUpload 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>`.
-
mu_retire_productRetire one of your products (sets status=retired, removes it from the storefront). Owner-only. Requires `Authorization: Bearer <api_key>`.
-
mu_update_productUpdate 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>`.
-
mu_submit_feedbackFound 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>`.
-
mu_ship_ordersList 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).
-
mu_ship_markAdvance 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.
-
mu_ship_csvGenerate 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.
-
mu_gi_logosList 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 brand's mark without permission is trademark misuse). Owner-only.
-
mu_gi_logo_setUpdate 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.
-
mu_ship_import_trackingPaste 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.
-
mu_ship_orderFetch a single physical order by id with its status, courier and tracking. Address/phone are masked unless reveal=true. Owner-only.
-
mu_gi_request_logosFor 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.
-
mu_gi_techpackReturn 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.
