AutoCAD-MCP
Client-neutral MCP server for AutoCAD automation: connects Codex, Claude Code, Cursor and any standard MCP client to full AutoCAD, AutoCAD LT or a headless DXF backend, with checked writes, handle readback and delivery evidence.
What it does and how it connects
AutoCAD-MCP connects Codex, Claude Code, Claude Desktop, Cursor, and any standard MCP client to full AutoCAD, AutoCAD LT, or a headless DXF backend. It is built for agents that must prove what they drew, not merely report that a script ran: checked writes with strict inputs, handle readback, requested-versus-actual diffs and document revisions; delivery evidence as DWG, DXF, PDF and PNG outputs, exported-DXF re-audit, paper and scale verification, geometry digests, manifests and SHA-256 hashes.
Three backends are offered: a native worker on Windows Python against full AutoCAD 2025/2026, a file IPC compatibility path against full AutoCAD or AutoCAD LT 2024 and later, and an ezdxf headless backend on any platform with no AutoCAD needed. Coverage includes structured 2D drawing, layers, dimensions, topology DRC, native AutoCAD solids and booleans, bounded product features, motion screening, and fixed-camera review views. A headless demo creates a mechanical DXF, runs semantic DRC, renders a deterministic PNG, and prints the evidence, with an expected result of ok true, six entities, and DRC status PASS.
The README states its honest limits explicitly: unsupported edge selection, shelling, exact continuous motion, and material rendering are reported instead of simulated. AutoCAD stays taskbar-visible but minimized by default, and drawing does not steal focus.

Recurring errors it addresses
Error Index entries this tool is built to reduce or work around.
- A DXF importer copied a rough 2 mm contour match into manufacturing identity, so two valid doors 1 to 2 mm apart could swap order-row identities and fail the strict cut check.Error Index
- An agent CAD edit landed (revision 2 to 3) but verification failed on an internal field mismatch, and recovery then failed because the tool's capability fingerprint changed between prepare and recovery on the same build, leaving the edit stuck half-verified. Issue #160 records the incident; PR #161 is the repair record.Error Index
Sources
Not verified
- Pricing: none stated on the repo.
- No independent user voice found: the repo has two public issues, both contributor pull requests.
- Version: the README badge claims version 4.0.0, but the latest GitHub release is v3.10.1 (2026-07-17) and the last push is 2026-07-19; the badge is ahead of the releases.
- Website: the repo homepage points back to the repo README itself, so no separate website is recorded.
