Agentic Fabrication Network (AFN) MCP Server

Create the order and get a hosted payment link for a chosen offer. Call this as soon as the user picks an offer + shipping speed — do NOT ask for their address first: the secure payment page collects the shipping address and email. Only pass address fields if the user already volunteered them. Returns checkout_url — give it to the user to pay; UFP places the vendor order automatically after payment.

Get ranked, purchasable offers (price, ETA, preview image) for fabricating a physical item from a design file. process=fdm_print for 3D printing a model (STL/OBJ/PLY/3MF/AMF/STEP/IGES), process=cnc or process=sheetmetal for machined/bent metal parts (STEP, IGES, DXF), process=decal for stickers/decals from artwork (any common image or design file — PNG/JPG/HEIC/TIFF/GIF/BMP/WEBP/AVIF/SVG/PDF/AI/EPS/PSD/CDR, auto-converted). A .ufp file (UFP part container: the design plus saved spec/constraints in one) is accepted anywhere a design file is — its saved intent applies automatically and anything the user states now wins. If the user just drops a file and asks for a price, omit process — UFP routes it. Provide the design either as design_file (an image/file the user attached or you generated — preferred) or file_url (a public URL). REORDERS: if the user has a UFP part number (from a receipt email or a previous session, looks like UFP-… or part_…), pass it as part_number INSTEAD of any file — the stored design and spec are reused and re-shopped across all current vendors. Locked parts additionally require share_key (from the owner's share link). Returns offers across vendors like Google Flights returns flights.

ONLY for the case where a quote response came back with an EMPTY board and told you to call this: waits for the vendors to answer (up to ~40s) and returns their offers as a full board. Call with just quote_id, immediately, and say nothing substantive before it. NEVER call it on a response that already listed offers — that board is final, and this would add nothing.

Record the user's verified-purchase review of how a UFP order turned out. YOUR JOB IS TO STRUCTURE THE FEEDBACK: turn what the user actually said into stars (1-5 overall) and facet scores — "the cut was sloppy" -> quality, "parts arrived 2 days late" -> timeliness, "wrong color" -> accuracy. Keep the optional comment to a short factual summary of their words; never embellish. ALWAYS draft the review (stars, facets, comment) and confirm it with the user BEFORE calling this tool — e.g. "I'll rate this 2 stars with timeliness 1 because it arrived 2 days late — send it?". One review per order: submitting again updates the existing review. Use list_orders first if you need to resolve which order they mean.

Honest, cited material intelligence for material-choice / strength / durability / heat / outdoor questions ("my PLA part broke, what's stronger?", "will this survive outdoors?"). Returns caveats-FIRST facts: published specs (tensile, heat-deflection, UV/outdoor, chemical) each tagged vendor-cited vs general engineering knowledge, "stronger/tougher/hotter than X" ladders (PLA→PETG→ABS/ASA→nylon/PC→metals), and finish/coating options. Call it BEFORE answering such a question, then relay the facts. It supplies FACTS ONLY — comparative specs and vendor-admitted caveats, never a fitness-for-purpose or safety guarantee (that stays your judgment boundary); name express vendor claims "advertised", not "certified".

The LIVE catalog of what the fabrication network can do RIGHT NOW — no quote needed. Returns the services ledger (tapping, inserts, welding, bending, finishes… with each shop's own size/material/thickness windows), the network's sheet gauge ladder, the stocked hardware combinations (species x thread) with stocked lengths and shop counts — the most-stocked length is the steering default for an unspecified length — the finish options with their stocked color menus, and per-process manufacturability rules. This is live state, not a spec sheet: it changes as connectors join, leave, or have capability branches toggled, so call it fresh when the user asks what's possible (materials, gauges, hardware, colors, services) rather than answering from memory.

Check status, ETA and tracking for a UFP order.

List this agent's recent UFP orders (newest first): order id, what was made, vendor, status, total, ETA, created date. Use it to resolve vague references — "my sticker order", "that order from 6 days ago" — to a concrete order_id before calling get_order_status or leave_review.

INTERNAL — the offer board calls this to refresh itself while vendors finish pricing. Never call this yourself. The board you were given is already final for its turn; do not reach for refine_quote to look at it again either, that paints a duplicate board.

INTERNAL client rail — the routing half of refine_quote with NOTHING committed: takes the same arguments as refine_quote and answers how many distinct fabricators (and which process lanes) the network WOULD ask for the refined part, plus the exclusion notes, without creating a child quote, asking any vendor, superseding in-flight work, or logging demand. An expectation, never a promise — lanes can still decline once asked. Never call this to look at prices; it carries none. Use refine_quote to actually re-price.

Narrow an existing quote with new constraints (destination ZIP the user just provided, deadline, outdoor/waterproof/heat/food-safety requirements, budget, vendor reliability, verbatim requirements terms, drawing callouts, a process filter — "no, I meant in sheet metal" → processes — a ship-from country filter — "only US vendors" → ships_from — or a vendor filter — "only show A3D Manufacturing" → vendors) — or CHANGE its spec: material, color, or quantities. Changing material/quantity is a spec change, not a narrowing — pass it via the material/color/quantities args, NOT as a requirements term; the affected lanes re-price with the new spec through warm vendor sessions. For side-by-side comparisons ("how does carbon steel compare?"), add a scenario label — labeled refines coexist instead of replacing each other (max 4). "Organize by" ("sort by cheapest", "soonest arrival on top", "most green first") is also this tool: sort_by for objective orders, sort_order + sort_label for orders you judged yourself from the previews — presentation only, instant, nothing re-prices. GOING BACK is also this tool: undo_last_step ALONE takes back exactly one refine step (the quote's steps[] names each step, newest first — the network restores the previous stored state exactly); clear removes whole constraints ("drop the deadline" → clear ["deadline"]); remove_requirements takes back individual requirements terms. Call with ONLY quote_id to re-read the quote (e.g. to pick up preview images that finished rendering).

Send the user's answer to a question the maker (vendor) asked about a UFP order — get_order_status surfaces an open question when one is waiting. Confirm the answer with the user before sending. The network relays it: the maker sees plain text from the network account with the user's contact details and links stripped, so never include emails, phone numbers, or URLs the answer depends on.

Every sheet thickness (gauge) ONE named shop stocks right now, per material — read live off the shop's declared catalog, no quote needed. Call it when the user asks what thicknesses/gauges a specific maker carries ("what thicknesses does SendCutSend have in mild steel?"). For the whole network's ladder use get_network_capabilities instead. Never answer a gauge question from memory.
