AutoCAD AI: MCP servers and agent skills

How AI connects to AutoCAD

An MCP server or skill can only do what AutoCAD lets programs do. AutoCAD exposes 5 automation interfaces:

• AutoLISP and Visual LISP (LISP): AutoCAD's built-in LISP interpreter runs code typed at the command line or loaded from .lsp files, and it is the only programming interface AutoCAD LT has: LT gained AutoLISP in the 2024 release on Windows, with only limited Visual LISP and ActiveX functions and no AutoLISP at all on LT for Mac. That is why LT-capable MCP servers, such as puran-water's, load a LISP dispatcher with APPLOAD and pass commands to it, and why several servers expose an "execute LISP" escape hatch. Documentation
• ActiveX Automation (COM) (COM automation): The AutoCAD.Application COM object lets an outside Windows process attach to a running session and work with documents, model space, layers and blocks, which is how most Python servers reach AutoCAD through pywin32. It needs full AutoCAD on Windows; LT has no external COM. Because ZWCAD, GstarCAD and BricsCAD expose look-alike COM objects, several of these servers also attach to those programs by changing the ProgID. Documentation
• Managed .NET API (ObjectARX) (.NET): C# or VB.NET assemblies loaded with NETLOAD or an ApplicationPlugins bundle run inside the AutoCAD process with full access to the drawing database and transactions. Add-in servers such as dwg-mcp and Nodal.AcadMcp take this route and talk to their MCP process over a named pipe or local HTTP. Plug-ins are compiled per release family, so each AutoCAD year may need its own build; Windows only, and not available in LT. Documentation
• AutoCAD Core Console and command scripts (Command line): accoreconsole.exe is AutoCAD without a user interface: it opens a DWG with /i, runs a .scr script with /s and can load AutoLISP, .NET and ObjectARX code, so agents can batch-process drawings without a visible session. Commands that open dialogs or palettes don't work there; use command line forms such as -LAYER instead. The Autodesk Developer Network skill teaches agents to test plug-ins this way. Documentation
• DXF file format (Input files): Autodesk documents DXF, the tagged text exchange format for drawings, group code by group code. Servers that work without AutoCAD write DXF through the ezdxf Python library, or read DWG through LibreDWG. That covers geometry, layers, blocks and text, but not everything a live session can do: offset, fillet and native DWG saving are often missing headlessly. Documentation

What Autodesk offers

AutoCAD 2027 installs a local MCP server that Autodesk Assistant, still a technical preview, uses to query, select and compare objects in the open drawing on Windows; Autodesk documents no way for outside clients to connect, and drawing creation isn't offered. The September 2026 release added xref, layer and system-variable tools. Autodesk's Product Help MCP server, public since April 2026, answers AutoCAD 2023–2026 documentation questions in Claude, ChatGPT, Cursor and Copilot without sign-in.

What you can do with AutoCAD and AI

• Draw and annotate in a live session from a plain description, such as lines, polylines, hatches, text, dimensions and blocks on named layers, then capture a screenshot to check the result.
• Clean up and revise an existing DWG, such as renaming layers, changing colour or lineweight, updating block attributes and adding revision clouds, with a record of what changed.
• Read a drawing someone else made and report its layers, blocks, text and extents, or query a DWG on a machine without AutoCAD and render a view to PNG.
• Produce P&ID sheets from a specification, placing tagged symbols and numbered process lines, then pull instrument, line and equipment lists back out.
• Translate drawing notes in place, regrouping fragmented text and switching to a Unicode text style so CJK or Vietnamese characters display.
• Port older AutoLISP routines to AutoCAD .NET plug-ins, or have a coding agent write and test a .NET plug-in, using Autodesk's own developer skills.

Installing

The listings here document setup for Autodesk Assistant, ChatGPT, Claude Code, Claude Desktop, ClawdBot, Codex, Cursor, Google Antigravity, Microsoft Copilot, OpenCode, TRAE, VS Code, VS Code (GitHub Copilot) and Windsurf. Install steps, copied from each project's own documentation, are on each listing's page. Most AutoCAD integrations run on your own computer next to AutoCAD, so you need AutoCAD installed and licensed on the same machine unless the listing says otherwise.
