Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00024 | $0.06133 |
| Opus 5 | $0.00012 | $0.03067 |
| Sonnet 5 | $0.00005 | $0.01227 |
| Haiku 4.5 | $0.00002 | $0.00613 |
Grade A, and why
3dsmax-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

3ds Max MCP — Agent Guide
Tool Profile Routing
- Full/core: Operational tools such as
query_sceneandcreate_objectare advertised directly; call the matching tool by name. - Progressive: If the advertised surface contains only
list_toolsets,describe_toolset, andcall_tool, never call an operational name as a top-level MCP tool. Choose the relevant capability withlist_toolsets, load only that group withdescribe_toolset, then invoke the selected operation throughcall_tool(name=..., arguments=...). - Do not describe every toolset up front. Load only the group needed for the current request; if the exact operational tool and arguments are already known,
call_toolcan dispatch it directly.
Principles:
- Match the user's request. Do not run setup, discovery, or scene analysis by habit.
- Do not call
get_bridge_statusorget_session_contextas a session preamble. - Prefer a dedicated MCP tool over raw MAXScript when a tool clearly matches the task.
- Do not render unless the user explicitly asks. Viewport capture is fine when visual proof is useful.
- Multiple Max instances:
list_max_instances,select_max_instance(pid),get_selected_max_instance, andrelease_max_instanceare available in every profile. The first successful native connection stays bound to that Max. Starting or claiming another Max only changes the default for unbound clients. If the selected Max closes, explicitly select another or release it; clients never silently switch.MCP_MAX_PIDorMCP_MAX_PIPEpins the startup target (MCP_MAX_PIPEtakes precedence). Release also clears startup pinning.
Tool Choice
Scene reads — use query_scene(action=...):
overview|filter|class|property|selection|deltaget_instances/get_dependencies— instancing and reference graphresolve_node_refs— turn a name, handle, or absolute JSON-Pointer hierarchy path into a canonical handle/name/path identity; multiple selectors are cross-checkedscene_qa(action="scan")— deterministic naming, transform, hierarchy/group, and timeline checks only; it never analyzes meshes, UVs, topology, normals, skinning, or visual qualityget_session_context— bridge + capabilities + overview + selection (on demand only)

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

3dsmax-mcp is a skill published in the GitHub repository cl0nazepamm/3dsmax-mcp (224 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 6,133 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
dcc-mcp-3dsmax-setup
Set up dcc-mcp-3dsmax for an agent or operator: install 3ds Max Python dependencies with 3dsmaxpy, generate MCP host configuration, guide the user through starting the runtime inside 3ds Max, and run a first live-tool smoke prompt.
3dsmax-asset-source
Domain skill — search and resolve assets into validated AssetDescriptor contracts for cross-DCC asset import pipelines. Returns static catalog entries; production sources can layer download helpers or remote resolution without changing the contract.
3dsmax-scene
Domain skill - open, save, merge, inspect, and manage scenes and objects in the current Autodesk 3ds Max session. Use for typed scene lifecycle, nodes, cameras, selection, visibility, parenting, grouping, pivots, transforms, scene metadata, or object cleanup.
3dsmax-geometry-io
Domain skill - validate geometry files and run host-native geometry import and export operations in Autodesk 3ds Max. Use for FBX/OBJ/3DS import checks, FBX import, FBX export, OBJ export, and structured import/export stats.
3dsmax-lookdev
Domain skill - configure OCIO color management, HDR environment lighting, preview materials, and assign renderer-specific materials (Arnold, V-Ray, Scanline) in 3ds Max.
3dsmax-render
Domain skill - capture viewports, render scenes to image files, create preview playblasts, configure renderers (Arnold, V-Ray, Scanline), produce HDR/EXR output and multi-pass AOV renders, inspect render settings and statistics, and adjust common render output options in 3ds Max.
