AutoCAD MCP tools

acad_drawing_info
Read drawing metadata — title block fields, revision history, sheet count, and drawing units.
acad_entities_list
List entities in a drawing or layer — lines, arcs, polylines, blocks, text, dimensions, and attributes.
acad_dimensions_get
Extract dimension values, tolerances, and associated geometry from a drawing or selected area.
acad_gdt_callouts
Read geometric tolerancing annotations (feature control frames, datum targets) per ASME Y14.5.
acad_blocks_list
List block definitions and their insertion points, attributes, and attribute values in the drawing.
acad_export_step
Export the drawing or 3D model to STEP or IGES neutral format via APS Model Derivative API.
AutoCAD toolsets — all included

Toolset coverage

AutoCAD toolsets are industry-specific drawing environments installed on top of AutoCAD. All are accessible through the same APS connection — the MCP reads whatever toolset files are stored in your Autodesk account.

AutoCAD toolsets run on Windows only. AutoCAD for Mac is a separate native macOS product — it does not include the toolset extensions. The ForgeMCP APS connection reads files created by any AutoCAD product or toolset regardless of the originating platform.

AutoCAD Plant 3D
Piping and instrumentation diagrams (P&IDs), 3D plant models, isometric drawings, and equipment lists.
AutoCAD Map 3D
GIS-connected mapping, geospatial analysis, and CAD drawings with attached geographic data.
AutoCAD MEP
Mechanical, electrical, and plumbing systems design — ductwork, conduit, and pipe routing.
AutoCAD Electrical
Schematic design, panel layouts, wire numbering, and component databases for electrical control systems.
AutoCAD Mechanical
2D mechanical design with standards libraries (ANSI, ISO, DIN, GB), BOM generation, and part references.
AutoCAD Architecture
Architectural objects (walls, doors, windows, stairs), space planning, and AEC coordination tools.
AutoCAD Raster Design
Raster-to-vector conversion, scanned drawing management, and geospatial image overlay tools.
AutoCAD for Mac Separate product
Native macOS AutoCAD application. Full 2D/3D drawing capability without toolset extensions. Files are fully readable via APS.
Use cases

What engineers use it for

📋
Drawing review
Ask Claude to read all title block fields, revision notes, and dimension callouts from an AutoCAD drawing — instantly assembling a review checklist.
⊕
GD&T verification
Extract GD&T callouts from AutoCAD drawings and pipe them into the GD&T Compute MCP to verify ASME Y14.5-2018 compliance — in one Claude session.
🔄
P&ID analysis (Plant 3D)
Read instrument tags, line numbers, and equipment from a Plant 3D P&ID and ask Claude to cross-check against your equipment list or generate a datasheet summary.
