AutoCAD MCP Pro
AutoCAD MCP server for AI agents with live COM and headless ezdxf engines, covering drawing automation plus GD and T and tolerance validation.
What it does and how it connects
AutoCAD MCP Pro is an MCP server that lets AI agents draw, edit, and read DWG and DXF drawings through 257 tools in version 1.8.0. It works live through COM on Windows with a real AutoCAD session, or headlessly with ezdxf anywhere, with no AutoCAD needed in the headless mode.
Coverage includes mechanical sheets with ISO GD&T and tolerances, P&ID diagrams under ISA-5.1, floor plans, and pipe and cable takeoffs. A verification workflow scores drawings through drawing_critique and drawing_finalize, with a durable operation journal, checkpoints, and an all-or-nothing cad_batch mode.
The README is explicit about limits: a DWG save is refused headlessly, some P&ID, settings, and architecture tracks have known limitations, and the native .NET worker is deferred to 1.9.0. It installs as a Claude Code plugin or from PyPI, and is MIT licensed.
What engineers report
Fix analysis_find_in_region: use SelectionSet.Select(acSelectionSetCrossing) instead of non-existent SelectCrossing (AttributeError on every call).
