render

MCP tool from Openscad MCP by RobertCoop

Images with a text digest before each one (camera, view direction, scale, bbox). mode=views (one image per view, or a custom camera), mode=section (exact cross-section with a scale bar), mode=parts (each part in its own colour, isolate ghosts the rest), mode=compare (before/after). grounded=true giv

How to use it

Project documentation lists render for the Openscad MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

measure

Exact numbers from the exported geometry: bbox, dimensions, volume, surface area, solid and cavity counts, watertightness, meshhealth. mode=parts measures each part of an assembly, mode=section returns cut contours with area, mode=mass adds grams for a material. Accepts an existing STL/SVG via mesh

reference

Sourced engineering data with confidence labels: fits and clearances, metric fasteners, heat-set inserts, bearings, magnets, joints, FDM design rules, materials, OpenSCAD cheatsheet, conventions

scad_eval

Evaluate expressions in a model's variable scope and get typed values (number, vector, string, bool, range, undef)

update_model

Update an existing model's content

validate

mode=syntax (parse and evaluate, no geometry), mode=geometry (mesh findings: open edges, non-manifold, several solids, cavities), mode=predicates (assert ["W > 10", "H == 2W"] in the model's scope), mode=includes (every include/use/import resolved or not)
