AutoCAD MCP is a free MCP server that lets AI assistants such as Claude, Codex and Cursor read and work with the drawings open in AutoCAD on your PC — entities, layers, blocks, text and dimensions, layouts and PDFs, xrefs and quality checks — and with DXF files.
Check this drawing and move what is on layer 0 to A-WALL.
Illustrative session. The assistant works with the AutoCAD installed on your PC.
71 tools and 24 skills for AutoCAD work, each capability with its state and the AutoCAD releases it was verified in (AutoCAD 2026 so far).
Open, create and save on request; list, count and filter entities; create lines, polylines, arcs, text, dimensions, hatches, tables and 3D solids; move, copy, rotate, offset, join.
Layers and layer states, linetypes, text and dimension styles, blocks, attributes and dynamic blocks.
Layouts and viewports, plotting to one PDF, DXF and WBLOCK export.
External references and every file a drawing depends on, with what is missing.
Drawing checks with findings by handle, comparison with a standard drawing, purge and audit.
Inspect or update text in DWG files without opening them; read, check and write DXF files without AutoCAD.
Not for AutoCAD LT (no .NET API). Running commands, AutoLISP and API methods is off unless you switch it on.
One file for AutoCAD MCP and its AutoCAD plug-in. Latest release: v0.1.0.
Run Install-AUTOCAD-MCP.cmd. If Windows asks whether to run it, choose Run.
It installs AutoCAD MCP and the plug-in for your Windows user, with an optional sign-in, and connects your AI assistants.
If AutoCAD asks about AutoCadMcp.dll, choose Always Load. If the Claude app is open, setup asks to restart it for you.
Prefer to do it by hand? See the release page.
AutoCAD MCP runs on your PC as autocad-mcp.exe, on local HTTP port 48891, for any AI assistant that speaks MCP.
autocad-mcp --cloud on.https://aecomcps.com/mcp/autocadSign in with the same Microsoft, Google or GitHub account as on your PC, start a new chat with AutoCAD MCP switched on, and keep AutoCAD open. What the AI reads from the drawing passes through the team gateway to the AI company; the gateway never stores or logs it.
Read and write self-tests passed in AutoCAD 2026; 2020–2025 and 2027 are designed for but not yet tested. Each capability says where it was verified.
Anything that erases, purges, replaces, closes or overwrites is shown first and needs your OK. Each change is one undo step; nothing is saved unless you ask.
The plug-in runs in the AutoCAD installed and licensed on your PC and listens only to your Windows account. AutoCAD asks once about it: choose Always Load.
AutoCAD MCP is a free Model Context Protocol (MCP) server for Autodesk AutoCAD, so AI assistants such as Claude, Codex, Cursor and VS Code can read and work with the drawings open in AutoCAD on your PC, and with DXF files on disk.
AutoCAD 2020 to 2027 on Windows, and AutoCAD-based products such as Civil 3D (as plain AutoCAD). It has been verified in AutoCAD 2026; the other releases are designed for but not yet tested, and every capability says where it was verified.
No. AutoCAD LT has no .NET API, so the plug-in cannot run in it. The DXF file tools work without AutoCAD.
The plug-in is not code-signed yet, so AutoCAD asks once whether to load it. Choose Always Load. The plug-in only listens to programs of your own Windows account on this PC.
No. Your drawings, their names and their contents stay on your PC. When you sign in, AutoCAD MCP shares only what the AI learned about using the tools, privacy-filtered.
Yes. AutoCAD MCP is free. You need Windows 10 or 11 (64-bit), and AutoCAD 2020–2027 for the drawing tools.
Download the installer on this page (Install-AUTOCAD-MCP.cmd) and double-click it. It installs AutoCAD MCP and its AutoCAD plug-in for your Windows user and connects your AI assistants. Then start AutoCAD.
