SolidWorks MCP Server

MCP (Model Context Protocol) server that lets AI assistants control SolidWorks — create parts, sketch, extrude, assemble, run FEA simulations, export files — all through natural language.

Architecture

AIClient(Claude/Cursor) ←→ MCP(SSE/stdio) ←→ SolidWorks API
 ├── 3DEXPERIENCE Cloud
 └── COMDesktop(Windows)

Quick Start

Local (stdio)

pip install-e.
python -m solidworks_mcp_server --backend dxp --transport stdio

Claude Desktop config:

{
"mcpServers":{
"solidworks":{
"command":"python",
"args":["-m","solidworks_mcp_server","--backend","dxp"],
"env":{
"DXP_BASE_URL":"https://your-platform.3dexperience.3ds.com",
"DXP_SPACE_ID":"your-space-id",
"DXP_API_KEY":"your-api-key"
}
}
}
}

Local (SSE)

$python -m solidworks_mcp_server --backend dxp --transport sse --port8000

Connect at http://localhost:8000/sse

Apify Actor

$apify push

Input:

{
"backend":"dxp",
"dxpApiKey":"your-api-key",
"dxpBaseUrl":"https://your-platform.3dexperience.3ds.com",
"dxpSpaceId":"your-space-id",
"mcpTransport":"sse",
"mcpPort":8000
}
