Data offered docs-verified: drawing file management (create, open, save, save as DXF, purge, undo/redo) · entity create/read/modify (lines, polylines, arcs, hatches, MText, copy/move/array) · layer management · block list, insert and attribute read/update · text, dimension and leader annotation · P&ID symbol insertion and connection · viewport zoom and screenshot capture · arbitrary AutoLISP execution (File IPC only)
Formats docs-verified: DXF · DWG · PDF · PNG · MCP stdio
Access llm-inferred: Open source, MIT licence. No API key or auth stated. The ezdxf headless backend needs no AutoCAD. The File IPC backend needs AutoCAD LT 2024+ on Windows 10/11 with Windows Python 3.10+ and uv.

Use cases llm-inferred: Headless DXF base-plan generation for drainage or civils layouts on Linux/macOS without an AutoCAD licence (ezdxf backend) · Batch read and update of title-block or schedule block attributes across drawing sheets · Scripted P&ID process-line and equipment tagging for water treatment schematics (File IPC with CTO symbol library)
Audience llm-inferred: CAD technicians · civils engineers · drainage engineers · BIM engineers · process engineers

Constraints llm-inferred: Not a geospatial or hydrological data source: no coverage area, time series or dataset content · File IPC backend needs Windows 10/11 and AutoCAD LT 2024+; AutoCAD LT for Mac has no AutoLISP · offset, fillet, chamfer and execute_lisp are File IPC only · ezdxf headless backend lacks plot_pdf, undo and redo · P&ID operations on File IPC need extra LISP helpers and the CTO P&ID symbol library · Metadata tool list (19 names) does not match the 8 consolidated tools described in the docs; verify tool names before use · Entry URL (andyluu98/vn-autocad-claude) differs from the docs' clone source (puran-water/autocad-mcp); provenance unverified

Check which backend is active: file_ipc if AutoCAD is running, otherwise ezdxf.
