lambdacad MCP server

This is a helper that connects your AI assistant to BricsCAD, a professional drawing program that runs on Linux. Once it is set up, you can just describe what you want and the AI draws it in the open drawing for you. It is handy if you work with technical drawings, plans or 3D models and use Linux.

What this MCP server does

You ask your AI for something like a room plan or a flange. The AI turns that into drawing instructions and hands them to this helper. The helper writes those instructions into a small file, nudges BricsCAD to read them, and waits for the answer. BricsCAD draws the lines, shapes or 3D solids, and the helper sends the result back to your AI. Your AI then tells you what it did, often with exact numbers like lengths, areas or volumes.

What you can do with it

• Draw 2D plans with lines, arcs, hatches and dimensions
• Create 3D solids and combine them with cuts and joins
• Generate 2D views from a 3D model
• Measure lengths, areas, volumes and check for collisions
• Place blocks, bolt circles and other repeated shapes
• Export your drawing as PDF, DXF or STL
• Check whether a part would print without supports

Try asking your AI

• “Draw the plan of a 4 by 3 meter room with a door and dimensions”
• “Make a DN80 flange: front view, hatched section, dimensions, then model it in 3D”
• “Check if any parts in this assembly overlap and tell me which ones touch”
• “Export the current sheet as a PDF and tell me the page size”

What it gives back to you

You get answers in the chat, not just a silent drawing. The AI can report exact lengths, areas, volumes, bounding boxes and whether two things collide. It can also tell you which drawing it worked in, what it changed, and whether a cut landed where you expected. When you ask for a file, it saves a PDF, DXF or STL and confirms the result.
