Production-grade AutoCAD automation for the Model Context Protocol — dual COM + headless ezdxf engines, 116 tools, ISO GD&T and dimension-tolerance validation, built for AI agents.
AutoCAD MCP Pro
Production-grade AutoCAD automation for the Model Context Protocol.
Dual-engine. Battle-tested. Model-agnostic.
116 tools · 5 resources · 5 prompt templates · COM + ezdxf backends
One MCP contract, two execution engines: drive a live AutoCAD instance over COM, or run fully headless on any OS with ezdxf — same tool surface, same response shapes.
New in 1.2 — 2D GD&T feature control frames + datum features (ISO 1101), ISO 129 dimension tolerances (±/deviation/limit/basic + text override), in-place editing of existing text and geometry (entity_edit_text / entity_edit_geometry), a friendly drawing_settings facade (units/scale/precision/osnap), and a scalar drawing-score + invalidity-ratio at drawing_finalize.
What makes it different
| AutoCAD MCP Pro | Typical AutoCAD MCP | |
|---|---|---|
| Live COM + headless ezdxf (one API) | ✅ | one or the other |
| Standards-validation gate (ISO 128 critique → finalize) | ✅ | ❌ |
| 2D GD&T authoring + datum-consistency gate (ISO 1101) | ✅ | ❌ |
| ISO 129 dimension tolerances (±/limit/fit text) | ✅ | ❌ |
| Deterministic OSNAP (no coordinate guessing) | ✅ | ❌ |
| Scalar drawing-score / invalidity-ratio | ✅ | ❌ |
| Security-hardened (AutoLISP allowlist, path guards, HTTP auth) | ✅ | rare |
| Test suite | 360 | few / none |
From the Author
I built AutoCAD MCP Pro because I needed it.
My day job at Anka-Makine revolves around intensive AutoCAD work — production drawings, parametric assemblies, strict layer standards across dozens of templates, dimensioning and block work under tight schedules, repeated audits, exports, and screenshots for design reviews. The repetitive parts of that workflow add up fast.
After months of leaning on this server inside my own daily workflow — and watching it shave hours off my week without a single misstep on critical drawings — I decided it deserved a public release. It works. It is fast. It stays out of the way.
The model on the other end of the wire does not matter. The Model Context Protocol is the contract; AutoCAD MCP Pro is one well-typed implementation of that contract. Any MCP-aware client — and the LLM behind it — sees the same 116 tools.
I will keep this repository actively maintained as my own use of it evolves, and a public benchmark suite is on the way — I want to give you numbers, not adjectives.

Why This Exists
Most CAD-automation tooling falls into two camps: heavyweight enterprise plug-ins that lock you into a single vendor, or one-off Python scripts that solve a single drawing and rot a week later. Neither plays well with the modern AI workflow, where the agent — not the engineer — is the one driving the tool.
AutoCAD MCP Pro takes a different stance:
- One protocol, two engines. A live COM backend talks to a running AutoCAD instance for in-app, real-time control. A headless ezdxf backend reads and writes DXF files anywhere — Linux, macOS, CI runners — with no AutoCAD installation required. Same tool surface, same response shapes, two execution modes.
- Built for agents. Every tool has a typed schema, a deterministic error contract, and structured progress updates. No string-parsing tricks; no positional-argument guessing. Pydantic on the way in, dataclasses on the way out.
- Hardened by default. Path traversal, command injection, AutoLISP escape, transaction-driven memory blowups, COM hangs — all addressed in the default configuration. You opt in to risk, never out.
Why It's the Best AutoCAD MCP
The AutoCAD-MCP field is crowded, but it clusters into a familiar shape: a
COM-only, Windows-only script with a handful of draw_line / draw_circle
tools, no tests, no security model, and — crucially — no idea whether the
drawing it produced is actually correct. Those projects let an LLM push
geometry. AutoCAD MCP Pro is built to let an LLM produce a drawing that passes
review. That difference is the whole thesis, and it shows up in five places no
other AutoCAD MCP covers at once:
1. It is the only one that checks its own work
Every competing AutoCAD/CAD MCP surveyed — COM scripts, the LT/AutoLISP servers,
the multi-CAD COM bridges — will happily emit a drawing with a leftover
construction line, a non-standard lineweight, an untrimmed corner, or two
dimensions stacked on top of each other, and report success. AutoCAD MCP Pro
runs a closed quality gate at drawing_finalize: an 8-step structural
validator plus an ISO-128 premium critique (lineweights, layer colours,
untrimmed corners, duplicate entities, leftover scaffolding, dimension overlap,
and GD&T datum consistency). Leftover scaffolding or an off-standard lineweight
blocks the gate instead of slipping into a review. This design-rule
validation is the durable moat — and it is exactly the capability Autodesk's own
in-AutoCAD AI demo leads with (automated compliance checking).
2. It speaks real engineering, not just geometry
- 2D GD&T (ISO 1101 / ASME Y14.5) — feature control frames and datum
features, with a gate that rejects a frame referencing an undefined datum. No
competing AutoCAD MCP, and none of the surveyed text-to-CAD products, ships 2D
GD&T authoring with validation. - ISO 129 dimension tolerances —
±/ deviation / limit / basic callouts
and fit text (⌀20 H7). A drawing without tolerances is not manufacturable;
most MCPs cannot express them at all. - Deterministic engineering primitives — involute gears (front view +
section A-A), DIN 6885 keyed bores, ISO 7200 title blocks — parametric, not
hand-drawn line-by-line by the model.
3. It removes the #1 LLM drawing error: guessed coordinates
Research on program-to-geometry (GeoGramBench, 2026) shows frontier models score
under 50% when they have to compute points. AutoCAD MCP Pro gives the model
deterministic OSNAP instead — point_from_snap, point_intersection,point_tangent return exact endpoints, intersections, and tangents so the model
never guesses a coordinate. selection_get even reads the user's live pick set,
so the AI edits exactly what was selected.
4. It runs where you run — live and headless
One tool surface over two engines: drive a live AutoCAD session over COM, or
run fully headless with ezdxf on Linux, macOS, or a CI runner with no AutoCAD
installed. Most competitors are COM-only (Windows + a running AutoCAD) or
file-only — not both behind an identical API with identical response shapes.
5. It is engineered like a product, not a demo
360 passing tests, a ruff-clean codebase, a security model that assumes
hostile input (AutoLISP allowlist with bypass-regression tests, path-traversal
guards, HTTP bind guard + bearer-token auth, per-call COM timeout), and a scalar
drawing-score + invalidity-ratio so quality is a number you can track across
releases — not an adjective. A reproducible correctness benchmark ships inbenchmarks/.
In one line: other AutoCAD MCPs help a model draw; AutoCAD MCP Pro helps
a model deliver a drawing that passes engineering review — validated,
toleranced, standards-compliant, on any OS, with the tests to prove it.
See the feature comparison at the top and the
Roadmap for how the moat widens from here (closed-loopcritique → repair refiner, ISO 286 fits, public benchmark numbers).
Highlights
Dual Engine Architecture
- COM backend: live AutoCAD control via the Win32 COM API, routed through a single-thread STA executor with a per-call timeout so an unresponsive AutoCAD never hangs the server.
- ezdxf backend: headless DXF file operations powered by ezdxf. Works on every platform, ideal for batch workloads and CI pipelines.
- Automatic backend selection, with a clean override via
AUTOCAD_MCP_BACKEND.

Production-Grade Plumbing
- FastMCP 3.0 lifespan-managed backend singleton
- Middleware stack: error handling, audit logging, timing, request logging

drawing_open, exports, batch ops) - 360 tests across drawing, entity, dimension, layer, block, analysis, batch/template, engineering, GD&T, premium, mocked-COM, and security suites
- Ruff-clean codebase, 360-test suite
Closed-Loop Quality Gate
drawing_finalizeruns both the 8-step structural validator and the premium ISO-128 critique (lineweights, layer colors, untrimmed corners, duplicate entities, leftover construction, dimension overlap) — leftover scaffolding or a non-standard lineweight blocks the gate instead of slipping through.- Deterministic geometry:
point_from_snap/point_intersection/point_tangentgive the agent exact OSNAP coordinates instead of guessed ones — the single biggest source of LLM drawing errors. - Cross-backend parity: the same
EntityInfo.propertiescontract, save-format-from-extension, offset side selection, and ARC length on both engines.
Security-First Defaults
- Path traversal & system-directory protection
- AutoLISP allowlist with regression tests for known bypass patterns (
vla-SendCommand,acet-*, alias tricks,funcallindirection,c:custom commands, error-handler hijacks) - Command sanitization for
system_run_command - HTTP transport refuses non-loopback bind without an explicit opt-in and a configured auth token
- Configurable file size limit on DXF input (
MAX_DXF_BYTES) blocks decompression-bomb-style attacks - Per-call COM timeout (
COM_CALL_TIMEOUT) prevents a hung AutoCAD from freezing the server
AI Client Compatibility
AutoCAD MCP Pro implements the Model Context Protocol. If a host can speak MCP, it can drive this server. No model-specific code, no per-vendor patches — the contract is the tool schema, and any MCP-aware client (and any LLM behind it) inherits the full 116-tool surface for free.

UUID-named selection sets, leak-free cleanup
The server boots once, the backend is initialized in the FastMCP lifespan, and every tool call is dispatched through the middleware stack:
ErrorHandlingMiddleware → AuditMiddleware → TimingMiddleware → LoggingMiddleware → tool
Tool returns are flowed back through _dc(), which converts dataclasses to JSON-serializable dicts and preserves the typed contract on the wire.
Security Model
AutoCAD MCP Pro assumes a hostile-input threat model: the MCP client may be untrusted, the model behind it may be jailbroken, and the inputs to every tool may be adversarial.
- AutoLISP allowlist —
security.pyblocks the full ActiveX/COM family (vla-*,vlax-*,vlr-*), Express Tools (acet-*), command channels (command,command-s,vl-cmdf), file I/O, code loading, indirection vectors (funcall,function,apply,eval), custom command invocation (c:*), and error-handler hijacks. Every known bypass is covered by a regression test. - Command sanitization — destructive AutoCAD verbs (
ERASE,PURGE,SHELL,SCRIPT,APPLOAD,NETLOAD,VBARUN, …) are rejected unlessDANGEROUS_COMMANDS_ENABLED=trueis set, in which case the server logs a loudWARNINGat startup and surfaces anunsafe_modeflag insystem_statusandsystem_about. - Path validation — every tool that takes a path runs through
validate_path(), which blocks traversal patterns, system directories, and constrains writes to a configurableALLOWED_PATHSlist. - HTTP transport guard — by default the server refuses to bind anything other than
127.0.0.1. To bind a non-loopback host you must opt in viaALLOW_REMOTE_HTTP=trueand setMCP_AUTH_TOKEN. - Resource exhaustion guards —
MAX_DXF_BYTESrejects oversize input,MAX_LIST_LIMITcaps response sizes, transaction snapshots persist to disk so memory stays bounded, andCOM_CALL_TIMEOUTkeeps a hung AutoCAD from taking the server with it.
If you find a security issue, please open a private contact rather than a public issue.
Benchmarks
Correctness — v1.1.0 vs v1.0.0
A reproducible A/B suite (benchmarks/) runs the same 21
deterministic, headless (ezdxf) checks against the public v1.0.0 release
(origin/main) and v1.1.0 — each check in its own subprocess, so a hard crash is
recorded as a miss instead of taking down the run.
| Version | Checks passing | Pass rate |
|---|---|---|
| v1.0.0 (public release) | 8 / 21 | 38.1 % |
| v1.1.0 (this release) | 21 / 21 | 100 % |
13 defects fixed · 0 regressions · 2.6× higher correctness pass-rate (+61.9 pts).
Fixes span dimensions (aligned/angular no longer raise), full-circle arrays, deterministic
geometry (point_intersection/point_tangent), ARC selection, property parity, MTEXT
rotation, the headless screenshot crash, the now-live dim_overlap critique, ISO-13567
layer routing, and gear-outline geometry. Six core operations pass on both versions, so
the suite is not a cherry-picked failure list — see benchmarks/README.md
for the full table, methodology, and honesty caveats.

Performance (throughput) — coming
A scale/throughput suite is in active development. Targets:
- Drawing scale — 1k / 10k / 100k entity workloads
- Workload classes — bulk creation, mass-modify, region select, render-and-screenshot, end-to-end design pass
- Backend variants — ezdxf on CPython 3.11/3.12, COM against AutoCAD 2024+
- Model compatibility — tool-call success rate and prompt token usage by model, on a fixed set of canonical CAD prompts
Numbers will land in benchmarks/ with a one-command runner and a hardware footprint. The table below will be updated as new models and AutoCAD versions release.
| Workload | ezdxf (3.12) | COM (AutoCAD 2025) | Notes |
|---|---|---|---|
| Open + audit 10k-entity DXF | coming | coming | |
| Bulk-create 5k LINE entities | coming | coming | |
| Region select on 100k drawing | coming | coming | |

Roadmap
Sequenced by dependency, not wishlist: each release builds on the one before it.
The theme is widen the standards-validation moat, then close the loop, then
reach production-drawing parity — and only then chase breadth.
Shipped
- 1.0 — Foundation. Dual COM + ezdxf engine, FastMCP 3.0 middleware stack, the core drawing / entity / layer / block / dimension / analysis tool surface.
- 1.1 — Correctness & the enforced quality gate.
drawing_finalizeruns the premium ISO-128 critique; deterministic geometry (point_intersection/point_tangent); dimension / save-format / polar-array / offset fixes across both engines; COM robustness (CoUninitialize, transaction & LISP guards); security hardening (HTTP bind guard, AutoLISP-allowlist bypass tests); mocked-COM harness. 318 tests. - 1.2 — ISO production + a measurable moat. 2D GD&T (ISO 1101) feature control frames + datum features with a datum-consistency gate; ISO 129 dimension tolerances (±/deviation/limit/basic + text override); in-place
entity_edit_text/entity_edit_geometry; thedrawing_settingsfacade; scalar drawing-score + invalidity-ratio at finalize. 360 tests.
Next — own the closed loop (the #1 accuracy lever)
- 1.3 — Closed-loop refiner. Iterative
critique → repair → re-critiquewith dedicated transaction-stack isolation, plus a pre-plan clarification pass indrawing_planthat surfaces missing/conflicting dimensions before any geometry. Depends on the 1.2 scalar score as its objective function. - 1.4 — ISO production depth. ISO 286 fit tables (
H7/g6→ resolved deviations feeding the 1.2 tolerance engine), a reusable ISO-25 dimension style, and MLEADER leader notes.
Then — prove it & harden it
- 1.5 — Public benchmark suite. A reproducible one-command runner in
benchmarks/(correctness + throughput by backend and model) — turns the "numbers, not adjectives" promise into CI-tracked figures, anchored on the 1.2 drawing-score. - 1.6 — Architecture & capability introspection. A backend
capabilities()map with per-tool enablement (e.g. auto-hidesystem_run_commandon ezdxf), plus aserver.pymodule split into a cleanservices/orchestration layer. - 1.7 — CI & coverage. Windows CI matrix exercising the mocked COM backend on every push, with a coverage gate.
Later — breadth (table-stakes elsewhere, deliberately deferred)
- 2.0 — Multi-document & paper space. Multi-drawing context, xref-aware tools, and first-class layout / paper-space + plot configuration.
- 2.1 — Optional 3D solids tier (COM-only). Extrude / revolve / boolean on the live COM backend; ezdxf intentionally stays 2D (no ACIS kernel), so this ships behind a capability flag rather than breaking dual-backend parity.
- 2.2 — Native Linux/macOS live control. Round-trip DWG via the ODA File Converter so headless hosts get true DWG in/out.
Requirements
- Python 3.11+
- FastMCP 3.0+
- ezdxf 1.3+
- (optional, COM backend)
pywin32306+, AutoCAD 2020 or newer - (optional, screenshots)
Pillow10.0+ - (optional, PDF export)
matplotlib3.8+
Contributing
Pull requests are welcome — especially around the COM backend (mocking, additional Windows tooling), benchmark suite contributions, and additional layer / dimension standards.
For non-trivial changes, please open an issue first to align on direction.
