Enables programmatic control of AutoCAD to create and manage drawings, allowing for the creation of lines, circles, arcs, ellipses, rectangles, polylines, text, and dimensions through natural language commands.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@AutoCAD MCP Server Draw a red circle at 100,100 with a radius of 50"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Draw in AutoCAD by typing plain English into Claude Desktop.
You type "draw a red circle at (100, 100) with radius 50" in Claude Desktop, and the circle appears in AutoCAD. No scripting, no LISP, no macros.
Claude Desktop sends your request to this server, which translates it into AutoCAD commands over the Windows COM interface.

You need all three:
Windows — the server talks to AutoCAD through COM, which only exists on Windows
Python 3.10 or newer
AutoCAD, GstarCAD, or ZWCAD installed
1. Install the server
git clone https://github.com/Porta048/autocad-mcp.git
cd autocad-mcp
pip install -e .2. Tell Claude Desktop about it
Open %APPDATA%\Claude\claude_desktop_config.json and add:
{
"mcpServers": {
"autocad": {
"command": "autocad-mcp"
}
}
}3. Restart Claude Desktop
That's it. Claude starts the server automatically — you don't run it yourself.
Open AutoCAD, then just talk to Claude:
Draw a red circle at (100, 100) with radius 50
Create a rectangle from (0, 0) to (200, 100)
Add text "Hello" at (50, 50)
Draw a line from (0, 0) to (100, 100)
Save the drawing to C:/drawings/test.dwgIf AutoCAD isn't already open, the server launches it and waits about 20 seconds for it to load.
Commands also work in Italian and Chinese — "disegna un cerchio rosso" does the same thing.

You don't call these by name — Claude picks the right one from what you ask.
Name a color in your request and it gets applied:

Also available: gray, black, orange, brown, purple, and pink. You can use the number directly if you prefer.
Written as (x, y) or (x, y, z) — z defaults to 0
X goes right, Y goes up
Angles are in degrees, counter-clockwise from the X axis
Edit src/autocad_mcp/config.json and set cad.type to AUTOCAD, GCAD, or ZWCAD:
{
"cad": {
"type": "AUTOCAD",
"startup_wait_time": 20
}
}Raise startup_wait_time if your CAD program is slow to open.
Nothing happens when you ask Claude to draw Check that Claude Desktop was restarted after editing the config file.
"CAD not initialized" Open AutoCAD manually first, then try again.

Confirm autocad-mcp runs from your terminal. If the command isn't found, pip install -e . didn't finish — run it again and watch for errors.
Errors are logged to autocad_mcp.log in the folder the server started from.
