What I built
A dependency-free Python MCP server and CLI for auditing STL meshes. Checks topology, grounding, connected shells, normals and feature-size heuristics before a CAD agent continues.
Developed with AI coding assistance. Source code, reproduction instructions and tests are available in the linked repository.
What was checked
40 automated tests passed locally on 27 October 2026.
Verification date: 27 October 2026. Tests cover the included fixtures and do not establish production performance.
What this demonstrates
Digital geometry checks with documented heuristics. A passing result is not a physical print, strength test or manufacturing-fit validation.
