MCP // BUREAU VS PRINTER CONTROL
MCP 3D Printing
MCP 3D printing is either printer control or a bureau API. AIURION's MCP is the bureau: a 24-hour guest token, three free quotes, Stripe Checkout after customer approval, and human review before capture. Connect at /api/agent/v1/mcp for STL, OBJ, STEP, STP, or 3MF files up to 5 MB; select an available material from the live capabilities response.
The endpoint is stateless HTTP MCP. It does not provide SSE, webcam frames, G-code streaming, or payment-card data.
QUICK RECOMMENDATION // SERVICE FIT
Is this the right service?
Choose AIURION's MCP when the agent should quote a manufacturing bureau. Choose Kiln, OctoEverywhere, or a local printer MCP when the agent should operate hardware you already own.

LIMITS // HONEST FIT
When this is not the best option.
The agent flow is a self-serve FDM quote on one printable file. It is the wrong tool when the job is an assembly stack, or when the customer needs a manufacturing quote that a slicer cannot answer.
One model per quote. Assemblies stay with a human.
The first version of the Agent API accepts one STL, OBJ, STEP, STP, or 3MF file per quote. Dedicated enclosure, workholding, gripper and stamping tools quote their complete sets. Arbitrary multi-part agent builds are out of scope. Outside the supported workbench sets, do not send nested assemblies, mating stacks, fastener maps, moving joints, or arbitrary kits. Those jobs need orientation, fit, and packaging review that a guest token cannot do.
Contact for assembly review →This is a file price, not an RFQ.
The structured quote is a slicer-based FDM price for one uploaded body: material, quantity 1–150, standard or rush, and US shipping or Bay Area courier. Self-serve base-print totals run from $100 to $500. It does not estimate inserts, finishing, mixed CNC-and-print work, BOM-level kits, revision comparisons, or “what would this cost if we changed the design.” If the price depends on assembly intent instead of one printable solid, skip the Agent API.
Use the human quote flow →BUREAU VS PRINTER CONTROL
Bureau service, not printer control.
Most MCP 3D printing tools drive a machine you already own. AIURION is the other kind: a shop an agent can quote, pay through Stripe after approval, and have manufacture the part.
The agent orders a manufactured part
- Upload STL, OBJ, STEP, STP, or 3MF to a San Francisco print bureau
- 24-hour guest token with 3 free quotes and no invitation
- Customer sees the quote, then Stripe authorizes the card
- A technician reviews the file before payment capture
- US shipping or Bay Area courier after production
The agent operates a printer you own
- Connects to Bambu, Klipper, OctoPrint, or a local fleet
- Pause, resume, webcam, G-code, and printer status
- No manufacturing quote and no Stripe bureau checkout
- No human manufacturability review by a shop
- No San Francisco production or courier handoff
SERVICE DETAILS // HOW IT WORKS
Seven tools. One shop job. No printer driver.
Connect an MCP client to https://aiurion.com/api/agent/v1/mcp and discover the current tool names and schemas with tools/list. printing.sessions.start is public. Later tools take that token as accessToken or as an Authorization Bearer header.
Remote MCP, not a local stdio installer
Point the client at /api/agent/v1/mcp. The server supports the stable 2025-11-25 protocol and compatible 2025-06-18 and 2025-03-26 clients.
prepare_workholding, quote_workholding, prepare_gripper, quote_gripper, prepare_stamping, quote_stamping, get_workbench_capabilities, prepare_enclosure, quote_enclosure, printing.capabilities.get, printing.sessions.start, printing.quotes.create, printing.quotes.get, printing.quotes.update, printing.checkout.create, printing.orders.get
Those tools cover capabilities, guest access, quote create/read/update, checkout after approval, and order status. There is no pause_print, resume_print, or get_webcam tool.
Approval and review stay outside the tool call
printing.checkout.create requires approvalConfirmed. Stripe collects the card. AIURION reviews the model before capture. Source-model storage paths and customer PII are not returned to the agent.
MAKER BENCH FOR AGENTS
From a reviewed design to a complete quoted set.
Your agent can prepare an enclosure, workholding fixture, gripper kit, or stamping die pair. Review the editable design and its limits, then quote the exact configuration. Open the returned link to review the complete set and approve checkout.
Start with get_workbench_capabilities to check availability and input schemas. Each enabled workbench has a prepare tool and a quote tool. The existing finished-model quote and order tools remain available.

KNOWLEDGE BASE // FAQ
Questions about mcp 3d printing.
These answers describe the current AIURION agent print service. The submitted file, application, quantity, and active production queue determine the final plan.
01 What MCP endpoint does AIURION expose?
https://aiurion.com/api/agent/v1/mcp. It is a public, stateless HTTP MCP server for quoting and tracking on-demand 3D prints of one file at a time.
02 How is this different from Kiln or OctoEverywhere?
Kiln and OctoEverywhere are printer-control MCPs: they talk to a printer you operate. AIURION is a bureau MCP: the agent sends a CAD file, receives a shop quote, and the customer pays through Stripe after approval. For supported enclosure, workholding, gripper and stamping sets, AIURION provides dedicated prepare and quote tools.
03 Can MCP tools quote a hyper-complex assembly?
No. printing.quotes.create accepts one model. Dedicated Maker Bench tools quote reviewed enclosure, workholding, gripper and stamping sets. Arbitrary mating stacks and assembly-level DFM still require human review. If the user asks the agent to quote a complex assembly, refuse the tool path and point them to /contact.
04 Can the MCP produce a complex manufacturing quote?
No. The quote tools return a slicer-based FDM price plus checkoutEligibility. They do not generate RFQs, BOM pricing, mixed-process estimates, or design-change quotes. Do not call printing.quotes.create as a stand-in for an estimator.
05 Can an AI agent quote a hyper-complex or multi-part assembly?
Finished-model quotes accept one model. Dedicated Maker Bench tools quote complete enclosure, workholding, gripper and stamping sets after review. Other nested assemblies, mating stacks, and custom kits need human review. Use the human quote tool for individual printable components, or contact AIURION when the assembly needs technical review before a price is meaningful.
06 Does the agent quote replace a manufacturing RFQ?
No. The agent receives a slicer-based FDM price and checkoutEligibility for one file. That is not an engineering quote. It will not price mixed processes, secondary operations, inserts, finishes, or a BOM. If the customer needs that kind of quoting, do not call printing.quotes.create; send them to /contact or the human upload flow.
07 Which MCP tools are available?
prepare_workholding, quote_workholding, prepare_gripper, quote_gripper, prepare_stamping, quote_stamping, get_workbench_capabilities, prepare_enclosure, quote_enclosure, printing.capabilities.get, printing.sessions.start, printing.quotes.create, printing.quotes.get, printing.quotes.update, printing.checkout.create, printing.orders.get. printing.sessions.start needs no prior credential. Capability discovery also needs no credential. Prepare and quote tools use the returned guest token or a permanent integration key.
08 Do I need the official MCP Registry to call it?
No. Any MCP client that can reach a remote HTTP endpoint can connect directly. Registry listings help discovery; they are not required for the guest session.
09 Can the MCP charge a card by itself?
No. printing.checkout.create returns a Stripe Checkout URL after explicit customer approval. Card data stays in Stripe. AIURION captures payment only after human model review.
START WITH THE FILE
Connect the bureau MCP, then quote a file.
Use /ai-agents for the full workflow and curl examples. Use /agentic-3d-printing if you need the category definition rather than the protocol details.
