Quick start
You need FreeCAD and uv / uvx. FreeCAD MCP has two components: an addon running inside FreeCAD and an MCP server launched by your client.
1. Install and start the FreeCAD addon
git clone https://github.com/neka-nat/freecad-mcp.git
cd freecad-mcp
Copy addon/FreeCADMCP into your FreeCAD addon directory,
then restart FreeCAD. Select the MCP Addon workbench and click
Start RPC Server in the FreeCAD MCP toolbar.
See the installation guide for platform-specific commands and screenshots.
2. Connect Claude Desktop
Add the following entry to claude_desktop_config.json:
{
"mcpServers": {
"freecad": {
"command": "uvx",
"args": ["freecad-mcp"]
}
}
}
Restart Claude Desktop to load the configuration, keep FreeCAD open with its RPC
server running, and ask Claude to create a model. Connections use localhost by
default.
