Available tools 28

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ship
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.
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.
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.
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.
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).
rfq
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`. RFQs are scoped to your account (admin sees all).
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).
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).
product
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, rashguard_ls, rashguard_black, hoodie, crewneck, sticker, mug, tote, tank, cap, phone_case, long_sleeve_tee, shorts, beanie, leggings, joggers, apron, canvas, metal_print, pillow, blanket, coaster, placemat, journal, mug_black, wine_glass, towel, bottle, mouse_pad, laptop_sleeve, poster, nfc_coin, device, event_ticket, song, zine, video, karaoke_ticket, house, socks, drawstring_bag, beach_towel, fanny_pack, bucket_hat, kids_tee, backpack, flag, printful_custom. `phone_case` is an iPhone tough case (Printful) — the buyer picks their iPhone model (11〜17, all sizes) inside checkout, so you create ONE product and it ships to whichever model they choose. . Two digital kinds need an extra field: `event_ticket` (a sellable event ticket — pass `capacity` for the seat limit; on purchase the buyer is emailed a QR that opens a VALID ticket page; no shipping) and `song` (a sellable track — pass `audio_url`, the https link to the audio; on purchase the buyer is emailed a private listen/download link; no shipping). Other digital kinds (`zine` PDF, `video`, `karaoke_ticket`) and manual-fulfilment kinds (`poster`, `tee_white`, `nfc_coin`, `device`, `house`) all take the same `design_url`/`ai_prompt` artwork; the buyer gets a download/redemption link (digital) or the operator ships/builds it (manual). Products go live immediately for trusted owners unless the risk gate trips, otherwise they wait for MA-council review — ALWAYS report the `status` field from the response, do not assume. Requires `Authorization: Bearer <api_key>`.
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>`.
affiliate
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>`.
logo
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.
logos
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 brand's mark without permission is trademark misuse). Owner-only.
mine
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>`.
mu
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 (material/dimensions/colors/print_method/placement/qty/size_range/embroidery_spec). Returns { ok, kind, report: { ok, gaps[], actions[] } }. Read-only, no API key. Use before mu_create_product or mu_rfq_create.
preview
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_sleeve_tee) to preview a custom print placement — passing the SAME position to mu_create_product prints exactly what you previewed (WYSIWYG). Usually answers in 10-45s; if it returns status="processing", call this tool again with the returned `preview_id` to keep waiting. Rate limit: 30 previews/hour. Requires `Authorization: Bearer <api_key>`.
quote
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`/`rashguard_premium`) OR a free-text `description` (e.g. "道着 for a dojo", "a seamless knit sweater") and the router infers the kind. Optional `qty`, `region` (e.g. jp/us), `budget` (JPY/unit). Read-only — creates nothing. No API key required. Options are ranked: buyable-now (auto + in budget) first. If an option's mode is `auto`, follow up with mu_create_product; if `quote`, it needs a human RFQ.
register
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.
request
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.
retire
mu_retire_product
Retire one of your products (sets status=retired, removes it from the storefront). Owner-only. Requires `Authorization: Bearer <api_key>`.
sales
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>`.
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.
status
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>`.
store
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>`.
submit
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>`.
techpack
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.
upload
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>`.
verify
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.

Mu — questions

Answers built from our own checks of this server.

What can Mu do?
It exposes 28 tools, read directly from the server on our last check. Among them: mu_affiliate, mu_check, mu_create_product, mu_create_store, mu_gi_logos, mu_gi_logo_set and 22 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Mu mostly used for?
Its tools cluster around ship, rfq and product. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Mu working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 649 ms. The bar chart above shows every period we have measured.
Is Mu still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Mu?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Mu need an API key?
No. Mu completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 28 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Mu?
It answers our handshake in 649 ms on average, which is faster than 14% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
