Autocad-MCP
240+ AutoCAD tools for AI agents to draw, read, and verify DWG/DXF files.
Drive live AutoCAD via COM or headless via ezdxf with 248 tools, 11 resources, and strict requirement verification.
Autocad-MCP exposes over 240 tools to AI agents like Claude and Cursor to generate and inspect CAD drawings. It operates live on Windows via COM or headlessly anywhere using ezdxf, eliminating the need for an active AutoCAD installation for headless tasks.
What it is
The server handles mechanical sheets with ISO GD&T, P&ID diagrams under ISA-5.1 standards, architectural floor plans with automated room calculations, and pipe or cable takeoffs. Version 1.7 introduces requirement verification, binding specs directly to geometry to catch discrepancies between dimensions and drawn features.
Who it's for
Suits mechanical, plant, and architectural engineers building automated CAD workflows with LLM agents. It does not suit users looking for a standalone desktop graphical editor without an MCP client agent.
Key features
Dual Engine Architecture
Run live AutoCAD via COM on Windows or execute headlessly anywhere using ezdxf without needing AutoCAD installed.
Requirement Verification
Bind source requirements directly to real CAD features, automatically catching dimension mismatches and geometry deltas.
P&ID and Plant Takeoffs
Generate ISO 10628-2 and ISA-5.1 compliant piping diagrams and export accurate pipe or cable takeoffs to workbooks.
Architectural Room Scheduling
Draw walls with hosted doors and windows while automatically measuring room areas and building schedules.

Our honest verdict
What's great
- Exposes 248 tools and 11 resources tailored for Claude, Cursor, and other MCP clients
- Performs headless DWG/DXF manipulation and rendering without requiring an AutoCAD license
- Provides strict requirement validation that measures real geometry rather than relying on text labels
- Includes specialized tracks for mechanical assemblies, P&ID, architecture, and takeoffs
Where it falls short
- Requires an MCP-compatible client like Claude or Cursor to interact with the tool server
- Live COM automation is restricted to Windows environments with AutoCAD installed
- Running and maintaining a production-grade agentic CAD pipeline demands python and GIS/CAD technical competence
Pricing & license
Free under its open-source license. The only cost is running and maintaining the software and your AI agent infrastructure yourself.

FAQ
Do I need AutoCAD installed to use this tool?
No. While live COM automation requires AutoCAD on Windows, the headless engine uses ezdxf to read and write drawings anywhere without an AutoCAD installation.
How does requirement verification work?
It binds source specifications to the underlying CAD geometry, measuring actual distances and features on the file rather than trusting dimension labels.
Which AI agents are supported?
Any MCP client can connect, with primary integrations optimized for Claude, Claude Code, and Cursor.
