3ds Max MCP is a free plug-in that lets AI assistants such as Claude, Codex and Cursor read and work with the scene open in 3ds Max on your PC — objects, modifiers, materials, lights, cameras, animation and rendering — with a preview before anything it cannot undo.
Give all the chairs a dark oak material and show me the viewport.
Illustrative session. The assistant works on the scene already open in your 3ds Max.
99 tools, plus the whole 3ds Max object model through MAXScript and Python when no tool fits. 176 capabilities are catalogued, each with its state and whether it was verified in a real 3ds Max.
Objects, classes, layers, hierarchy, selection sets, units, file state and references, filtered and paged for big scenes.
Create, transform, clone, align, group and link objects; edit poly and mesh geometry; user properties.
Add, edit, reorder and collapse modifiers, with sub-object selection; every installed modifier class is reachable.
Create and assign materials and multi-materials, set maps, use material libraries, UVW mapping and unwrap.
Add and adjust lights and cameras, aim them, and set the viewport to a camera.
Render settings, presets, render elements, test renders and batch renders, as background jobs when they take long.
Time range, keys, controllers, Morpher and Skin.
Import and export (FBX, OBJ and every installed format), save and merge scenes, find missing textures and relink or collect them.
The plug-in runs inside 3ds Max and works through 3ds Max's own MAXScript and Python. Your AI assistant starts max-mcp.exe, which talks to every open 3ds Max on the PC.
With several 3ds Max windows open, the assistant asks which one you mean. Lengths are in the scene's system units, rotations in degrees as the UI shows them, times in frames.
One file, one sign-in, no administrator rights. Latest release: v0.1.3.
Run MaxMcp-Setup.exe. If Windows asks whether to run it, choose More info › Run anyway.
Setup lists the 3ds Max versions on your PC and installs the plug-in for all of them. It asks you to sign in once with Google or GitHub, then connects your AI assistants.
If the Claude app is open, setup offers to restart it for you (your chats are kept). Otherwise quit it from its icon by the clock, open it again and start a new chat.
For IT and scripts: MaxMcp-Setup.exe /quiet installs without a window (then sign in with max-mcp.exe --login --gui). All files are on the release page.
Setup connects every AI assistant it finds on your PC. Restart the assistant, or start a new chat, after it was connected. By hand: max-mcp.exe --setup auto.
Cloud AIs in the browser need a remote MCP address. 3ds Max MCP serves your own PC only, so the scene never leaves it.
The assistant checks the scene first, previews larger changes and asks before anything it cannot undo.
Every change is one step “MCP: …” in 3ds Max's undo list. A change that fails part-way is rolled back.
Deleting, collapsing, removing modifiers or layers and opening or resetting a scene always show a preview, and happen only after your yes.
A file is never overwritten without asking, and the scene is saved only when you ask.
Read-only mode, scripts (MAXScript, Python) and 3ds Max commands can each be switched off in the settings, or for the whole team.
While a dialog is open in 3ds Max, the assistant waits and then tells you; close it and say “try again”.
The scene never leaves the PC, and there is no cloud relay. Only privacy-filtered AI learning is shared with your team.
A version counts as verified only after the self-test passed in a real 3ds Max of that version.
The read, write and file self-tests passed in both, and a live MCP test.
The plug-in is built for them and installed by the same setup, but nothing was run in them yet.
3ds Max MCP is a free plug-in for Autodesk 3ds Max with a Model Context Protocol (MCP) server, so AI assistants such as Claude, Codex, Cursor and VS Code Copilot can read and work with the scene open in 3ds Max on your PC.
3ds Max 2022 to 2027 on Windows. One setup serves all of them. It is verified live in 3ds Max 2025 and 2026; 2022, 2023, 2024 and 2027 are built for but not yet run in a real 3ds Max.
Inspect and change the scene: objects, transforms, hierarchy, layers, modifiers, editable geometry, materials and maps, UVs, lights, cameras, animation keys and controllers, rendering, import and export, and asset paths. When no tool fits, it can run MAXScript or Python (pymxs). Every change is one Undo step.
Yes. 3ds Max MCP is free. You sign in once with a Google or GitHub account, the same account as for the other products.
No. Setup installs 3ds Max MCP for your Windows user only, and it updates itself the same way.
Claude Code, Claude app, Codex, Cursor, VS Code, Gemini CLI and other MCP clients on your PC, connected by setup. ChatGPT and claude.ai in the browser are not supported: 3ds Max MCP serves your own PC only.
No. Object, layer, material and file names, values and images stay on your PC and with your AI assistant. Only privacy-filtered AI-learning information (which tool failed and how it was fixed, in general words) is shared with your team.
Download the installer on this page (MaxMcp-Setup.exe) and run it. It lists the 3ds Max versions on your PC, installs the plug-in without administrator rights, asks you to sign in once and connects your AI assistants.
