Whose server it is

Registry nameio.printpal/printpalverified in the MCP registry

The registry name sits under printpal.io. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

search
Search everything on PrintPal for a 3D-printing query: community 3D models, free tools and calculators, wiki troubleshooting articles, OpenSCAD/AI-CAD docs, video tutorials, build guides and Academy courses. Returns ids accepted by…
fetch
Fetch the full content of a PrintPal item returned by `search` (or any id of the form `model:<uid>`, `tool:<slug>`, `wiki:<slug>`, `doc:<slug>`, `resource:<slug>`, `project:<slug>`, `course:<slug>`). Returns the complete text (article…
search_3d_models
Find printable 3D models (STL/3MF/OBJ) in the PrintPal community library by keyword — e.g. "articulated dragon", "headphone stand", "Raspberry Pi 5 case". Returns cards with thumbnail, author, tags, likes and a link to the model page…
get_3d_model
Get full details for one PrintPal model by uid: description, license, file formats, author, stats, and the page URL to download it. Accepts a uid from `search_3d_models` results or a printpal.io/model/<uid> URL.
find_3d_printing_tool
Recommend the right free PrintPal browser tool for a task: print cost / resin cost / layer height (magic numbers) / E-steps / flow rate / volumetric flow / filament spool / drying / shrinkage / Vref / Etsy profit calculators; generators…
calculate_print_cost
Estimate what an FDM print costs (material, electricity, machine wear, labor, failure allowance) and a suggested selling price. Needs the print weight in grams and time in hours from the slicer; all other inputs have sensible defaults (1…
calculate_filament_usage
Convert filament grams to metres (and back), compute volume and cost, and estimate how much is left on a spool from its gross weight. Knows densities for PLA, PETG, ABS, ASA, TPU, Nylon, PC, CF blends. Give either `grams` or `meters`.
calculate_layer_heights
Compute the Z-axis "magic number" layer heights for a printer from its stepper step angle, microstepping and lead-screw pitch/starts, filtered to what suits the nozzle. Defaults match most Ender/Prusa-style printers (1.8°, 1/16, T8 2 mm ×…
calculate_volumetric_flow
Check whether a hotend can keep up: volumetric flow (mm³/s) = layer height × line width × speed, compared against the hotend limit, plus the maximum safe speed. Accepts a hotend preset name (stock, v6, bambu, volcano, rapido, high-flow…
search_build_guides
Find step-by-step PrintPal build guides: Arduino/ESP32 electronics + 3D-printed enclosures, robots, functional prints, printer mods, STEM classroom projects, props and toys. Each result lists difficulty, time, cost, part/file/step counts…
get_build_guide
Read a full PrintPal build guide by slug: summary, bill of materials with quantities and links, downloadable files (STL/3MF/code), every build step, callouts and code blocks. Use when the user wants to actually follow or adapt a project.
search_learning_resources
Search PrintPal's how-to content: the vendor-neutral 3D printing wiki (print quality, filaments, slicer settings, maintenance, error codes, safety), OpenSCAD + AI-CAD docs, short video tutorials with transcripts, and free Academy courses…
generate_3d_model
Turn a text prompt or an image into a print-ready 3D mesh (STL/GLB/OBJ geometry) with PrintPal's AI generator. Without a PrintPal API key this returns a link that opens the generator on printpal.io with the prompt prefilled; nothing is…
check_3d_generation
Poll a PrintPal AI generation started with `generate_3d_model` in API-key mode. Returns status (queued/processing/completed/failed) and, when completed, a time-limited download URL for the mesh.
design_parametric_cad
For mechanical / functional parts with exact dimensions — brackets, enclosures, adapters, gears, bins, knobs, mounts — open PrintPal's AI CAD agent with a ready-to-run brief. The agent writes editable OpenSCAD with parameter sliders, live…
get_pricing_and_plans
Explain what is free on PrintPal, how AI generation credits and the CAD agent are priced, API access and the on-demand 3D printing service — with links to sign up, buy credits or subscribe. Call when the user asks about cost, limits…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "printpal": {
      "type": "http",
      "url": "https://printpal.io/mcp"
    }
  }
}

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
