MCP tools · 13 exposed · ~2,150 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
check_printability ~176

Use this when someone attaches an STL, 3MF, STEP or OBJ file and wants to know whether it will 3D print well: size, walls, mesh problems and what to change. It reads the file, runs the same automatic design checks as our website, and stores nothing. It gives no quote. When no file is attached, it returns a link to upload the file on our website.

NameTypeReqDescription
materialstring–Material id the part would be printed in, if the user named one, one of the listed values.
model_fileobject–The STL, 3MF, STEP or OBJ file the user attached.

combine_quotes ~126

Use this when someone has two or more quotes from 3D Printer on Demand in this chat and wants to order the parts together. It takes the private quote links, saves one quote that holds all the parts, and returns its private link with one combined total and one shipping charge, next to what the quotes cost ordered one by one. It does not change the earlier quotes, and it does not take a quote made outside this chat or a part still waiting for a person.

get_print_quote ~240

Use this when someone asks how much it costs to 3D print a part, or wants a quote to have a 3D model (an STL, 3MF, STEP or OBJ file) printed and shipped by 3D Printer on Demand. It reads the attached file, checks that it can be printed, saves the quote, and returns the estimate with a private link that opens the saved quote on our website. When no file is attached, or the file type cannot be read, it returns a link to upload the file on our website. It does not cover drawings or photos.

NameTypeReqDescription
colorstring–Color name for the chosen material. Default is the material's first color.
materialstring–Material id, one of the listed values. Default petg.

quote_from_link ~317

Use this when someone shares a link to a 3D model, such as a model page on Thingiverse or Printables or a direct link to an STL, 3MF, STEP or OBJ file, and wants a quote to have it printed and shipped by 3D Printer on Demand. It reads the model's licence where the site publishes one, gets the file, checks that it can be printed, saves the quote, and returns the estimate with a private link that opens the saved quote on our website. When the link offers several files, it lists them to pick from. Links that are not model pages with a licence need the person to confirm they have the right to print the file.

NameTypeReqDescription
colorstring–Color name for the chosen material. Default is the material's first color.
file_keystring–The file_key of one file from an earlier answer that listed several files for this link.
linkstringyesThe link to the model page or to the file, starting with https.
materialstring–Material id, one of the listed values. Default petg.

recommend_material ~219

Use this when someone wants help choosing which of our plastics suits a part, from where it will be used: indoor or outdoor, heat, impact, flexing, chemicals, looks and material cost. It returns the materials we offer that fit, best match first, the reasons in plain words, and the ones ruled out and why. It does not rank materials by strength or stiffness, and it sends safety-critical parts to a person.

NameTypeReqDescription
appearancestring–high when looks and color choice matter.
chemical_exposurestring–Contact with oils, fuels, cleaners or solvents. Default none.
cost_sensitivitystring–high when keeping material cost low matters most.
environmentstring–Where the part lives. Default indoor.
flexibilitystring–flexible for parts that must bend and spring back, rigid for parts that must not.
heat_exposurestring–How much heat the part sees in use. Default none.

reorder_from_order ~103

Use this when someone wants the same parts again from an earlier 3D Printer on Demand order. It takes the private order link from their order email, works out a new estimate for each part from the files saved with that order, and returns a private link to review the parts and order them on our website. It takes no payment and does not change the earlier order.

size_hole_or_tolerance ~180

Use this when someone asks what clearance or hole size to draw for a printed fit: a sliding part, a bolt or pin through a hole, two printed parts that mate, a press fit, or a snap fit. It returns published starting clearances and hole guidance, each with its source, and how to test the fit. It gives no single universal hole offset, because none is published.

NameTypeReqDescription
fit_typestring–What the fit is for: sliding-moving, bolt-clearance, pin-in-hole, mating-fdm-parts, press-interference or snap-fit.

update_print_quote ~160

Use this when someone wants a different quantity or color on a quote 3D Printer on Demand already gave them. It takes that quote's private link and the new quantity, works out the estimate again from the file saved with the quote, saves it, and returns the new estimate with a new private link. The earlier link keeps the earlier quote. It does not take a new file, a different material, or a link that did not come from one of our quotes.

NameTypeReqDescription
