How to Set Up and Use CATIA V5
The CATIA V5 MCP Server connects AI assistants to CATIA V5 CAD software running on Windows via COM automation, exposing over 50 tools covering part creation, 2D sketching, 3D modeling operations (pad, pocket, fillet, pattern), assembly constraints, analysis functions, and multi-format export (STEP, IGES, STL). This lets engineers describe mechanical designs in natural language and have Claude or another AI assistant drive CATIA V5 directly, automating repetitive modeling and design validation tasks.
Prerequisites
- Windows OS (COM automation is a Windows-only technology)
- CATIA V5 R2016 or later installed and licensed
- Python 3.10+ with pip
- pywin32 library for COM automation
- Claude Desktop or Claude Code as the MCP client
Clone the repository
Clone the CATIA V5 MCP Server repository to your Windows machine.
git clone https://github.com/daiemon12/catia-v5-mcp-server.git
cd catia-v5-mcp-serverRun the setup script
The included setup.sh (run via Git Bash or WSL) installs all Python dependencies including mcp and pywin32 automatically.
bash setup.shManual dependency install (alternative)
If you prefer not to use the setup script, install the required packages directly with pip.
pip install mcp pywin32
# or
pip install -e .Start CATIA V5
Launch CATIA V5 before starting Claude or invoking any tools. The MCP server connects to an already-running CATIA V5 instance via COM. If CATIA is not running, the server will attempt to launch it if it is registered as a COM server.
Configure Claude Desktop
Add the server to your Claude Desktop config file at %APPDATA%\Claude\claude_desktop_config.json.
{
"mcpServers": {
"catia-v5": {
"command": "python",
"args": ["-m", "catia_mcp"]
}
}
}Verify connection via Claude Code (optional)
Alternatively, add the server directly through the Claude Code CLI.
claude mcp add catia-v5 python -- -m catia_mcpCATIA V5 Examples

}Prompts to try
Example natural-language prompts to control CATIA V5 through the MCP server.
- "Create a new part with a 100x60mm rectangle sketch, then pad it to 40mm"
- "Design a mounting bracket: 120x80mm base, 5mm thick, four M6 holes at the corners with fillets"
- "Export the current part to STEP format and save a screenshot of the isometric view"
- "List all parameters in the active document and change the pad height to 60mm"
- "Add a 3mm fillet to all edges of the current solid"Troubleshooting CATIA V5
Server fails to connect to CATIA V5 with a COM error
Make sure CATIA V5 is already running before you start a Claude session. If CATIA is not registered as a COM server, you can register it by running 'cnext.exe /regserver' from the CATIA installation directory in a Command Prompt with administrator privileges.
pywin32 import error or 'No module named win32com'
Run 'pip install pywin32' and then run the pywin32 post-install script: 'python Scripts/pywin32_postinstall.py -install' from your Python Scripts directory. This registers the COM support DLLs correctly on Windows.
Tools work but geometric operations produce unexpected results
CATIA V5 is sensitive to the active document and workbench context. Ensure the Part Design workbench is active for 3D operations and the Sketcher is active for 2D sketching. Use the 'list all documents' or context-inspection tools first to confirm CATIA's current state.
