CATIA V5 MCP servers and AI agent skills

How AI connects to CATIA V5

An MCP server or skill can only do what CATIA V5 lets programs do. CATIA V5 exposes 2 automation interfaces:

• CATIA V5 Automation (COM) (COM automation): CATIA V5 exposes documents, Part Design shape factories, hybrid shape (GSD) objects and products as COM automation objects. The MCP servers here reach it from Python through pywin32, which means Windows only and a running CATIA under the same Windows user and elevation level. Older releases differ in detail: one server needed a stale gen_py cache cleared on V5R20, and another gates legacy releases behind a setting. Dassault's automation documentation sits behind a 3DEXPERIENCE ID sign-in. Documentation
• pycatia (Python wrapper) (Python): pycatia is an open-source Python library that wraps the CATIA V5 COM interface in documented Python classes. One listed server names it as a possible alternative back end to raw win32com calls, and it is a useful reference when an agent needs to write V5 automation code itself. Documentation

What Dassault Systemes offers

Dassault Systèmes puts its AI into the 3DEXPERIENCE platform through virtual companions such as AURA, which works on content stored on the platform and in 3DSwym. It has not released an MCP server for CATIA V5 or for CATIA on 3DEXPERIENCE as of 4 November 2026. The CATIA V5 servers listed here are independent projects that use the desktop COM interface.

What you can do with CATIA V5 and AI

• Create a CATPart with sketches, pads, pockets, shafts, holes and fillets from a written specification.
• Build Generative Shape Design surfaces such as lofts, sweeps, fills and blends, then join and trim them.
• Assemble components in a CATProduct with fix, coincidence, offset and angle constraints.
• Measure distances, inertia and bounding boxes, and edit parameters, formulas and design tables.
• Set up a native CATIA Analysis case with supports, loads and a mesh, run it and save the HTML report.
• Export STEP, IGES, STL or 3DXML and create drawings with projection and section views.

Installing

The listings here document setup for Claude, Claude Code, Claude Desktop, Cline, Codex, Cursor, VS Code and Windsurf. Install steps, copied from each project's own documentation, are on each listing's page. Most CATIA V5 integrations run on your own computer next to CATIA V5, so you need CATIA V5 installed and licensed on the same machine unless the listing says otherwise.
