Solid Edge MCP Server

AI-assisted CAD design through the Model Context Protocol. Create, analyze, modify, and export Solid Edge models — all from your AI assistant.

252 MCP tools | 404 unit tests | Windows-only (COM automation)

What It Does

This MCP server gives AI assistants (Claude, etc.) full access to Solid Edge CAD workflows:

• Connect to Solid Edge application via COM automation
• Create and manage parts, assemblies, sheet metal, and drafts
• Sketch 2D geometry - lines, circles, arcs, rectangles, polygons, splines, constraints
• Create 3D features - extrude, revolve, sweep, loft, helix, cutouts, rounds, chamfers, holes
• Query and analyze models - dimensions, mass properties, feature trees, materials
• Assemblies - place components, move/rotate, BOM, interference checks
• Draft/Drawing - create views, annotations, parts lists
• Export models to STEP, STL, IGES, PDF, DXF, Parasolid, JT
• View control - set viewpoints, zoom, camera, display modes

Quick Start

Install

# Requires Python 3.11+ and Windows (Solid Edge is Windows-only)
uv sync --all-extras

Configure Claude Code CLI

Add to your MCP configuration file at ~/.claude/mcp_config.json:

{
  "mcpServers": {
    "solidedge": {
      "command": "uv",
      "args": [
        "--directory",
        "C:/path/to/SolidEdge_MCP",
        "run",
        "solidedge-mcp"
      ],
      "env": {}
    }
  }
}

Configure Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "solidedge-mcp": {
      "command": "uv",
      "args": ["--directory", "C:/path/to/SolidEdge_MCP", "run", "solidedge-mcp"]
    }
  }
}

Run Standalone

uv run solidedge-mcp

Verify Setup

1. Restart your AI client if it's running
2. The SolidEdge MCP server will auto-start when needed
3. Ask: "Connect to Solid Edge" to test

Troubleshooting

If the server doesn't load:

1. Check that uv is in your PATH
2. Verify the directory path is correct
3. Test manually: uv --directory C:/path/to/SolidEdge_MCP run solidedge-mcp
4. Check your client's logs for errors

Architecture

COM Automation Backend

The server communicates with Solid Edge through Windows COM automation (pywin32):

• Connection management - Connect to running instance or start new one
• Document handling - Create, open, save, close parts and assemblies
• Sketching - 2D profile creation on reference planes
• Features - 3D modeling operations (extrude, revolve, etc.)
• Assembly - Component placement, constraints, patterns
• Query - Extract geometry, dimensions, properties, materials
• Export - Convert models to standard CAD formats
