DrawPad MCP

This repository is where DrawPad MCP is released and supported: DrawPad.mcpb for Claude Desktop is on the Releases page, and bugs and requests go in Issues. All of Opticell's free tools for Claude: opticell-mcp.

Let Claude design things you can 3D-print. Ask for "a keychain that says LUNA", "a 60 mm star cookie cutter" or "a plant label for basil". Claude builds it with the engine from DrawPad Pro.stl, shows you a preview, and saves a watertight STL for your slicer plus a DrawPad project you can keep editing on iPad.

macOS (Apple silicon and Intel).

Install

Claude Desktop: download DrawPad.mcpb from https://www.opticell-limited.com/drawpad and double-click it.

Claude Code

claude mcp add drawpad -- npx -y @opticell/drawpad-mcp mcp

Any other MCP client: run npx -y @opticell/drawpad-mcp mcp as a stdio server.

What Claude can do

Templates: keychain, cookie cutter (heart, star, circle, flower, cloud or any outline), name sign, coaster, gift tag, stencil.
Custom designs: circles, rectangles, polygons, stars, hearts and text, with holes, stacked layers and thin walls, all in millimetres.
Check an STL: size, volume, filament weight, and whether it's watertight.

Every design reports its size, volume and grams of PLA/PETG, and comes with a rendered preview. Files go to ~/Documents/DrawPad Designs.

Open designs in DrawPad Pro.stl

AirDrop the .lsproj file to your iPad or iPhone, or save it to iCloud Drive, and open it. DrawPad imports it as a new project, and templates stay editable.
