MCP servers and automation bridges for CATIA, SolidWorks, Siemens NX, and Autodesk Fusion
Overview
Windows-focused MCP servers, application bridges, engineering Skills, and reproducible modeling examples for AI-assisted CAD/CAE workflows. Each MCP directory contains its own setup and validation instructions. These integrations require the corresponding proprietary CAD application and must generally run under the same Windows user and integrity level as that application. This repository intentionally contains source code, tests, schemas, portable configuration examples, and documentation only. Local workspaces, solver jobs, caches, logs, dependency copies, screenshots, and generated CAD binaries are excluded. Example paths such as C:\path\to\CAD-Agent-Hub must be replaced with the local clone path. Run each MCP project's documented unit tests before using it with a live CAD session. A successful COM/API call is not by itself proof that a model, mesh, drawing, or simulation result is correct; inspect the native application state and generated artifacts.

Repository scope
This repository intentionally contains source code, tests, schemas, portable configuration examples, and documentation only. Local workspaces, solver jobs, caches, logs, dependency copies, screenshots, and generated CAD binaries are excluded. Example paths such as C:\path\to\CAD-Agent-Hub must be replaced with the local clone path.
Validation
Run each MCP project’s documented unit tests before using it with a live CAD session. A successful COM/API call is not by itself proof that a model, mesh, drawing, or simulation result is correct; inspect the native application state and generated artifacts.
