What is blender-mcp-operator?

A Blender-operating role for creating 3D assets for Roblox games. It can use text or images to generate models, find external 3D and material assets, edit scenes, apply textures, and export FBX files.

Use it to create or import props, weapons, characters, and other 3D assets; inspect and edit Blender scenes; apply materials; optimize meshes; and export game-ready files.

It brings model creation and Roblox-specific optimization into the asset workflow, including limits on mesh complexity and texture size.

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.

Token cost

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	$0.00090	$0.01466
Opus 5	$0.00045	$0.00733
Sonnet 5	$0.00018	$0.00293
Haiku 4.5	$0.00009	$0.00147

Security

Grade A, and why

blender-mcp-operator 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 9d 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.

Tool Usage Guide

Generation Workflow

generate_hyper3d_model_via_text — Give a detailed prompt: "low-poly medieval sword, stylized, game-ready, PBR textures"
get_hyper3d_status — Poll until generation completes (may take 30-120 seconds)
import_generated_asset — Import into the Blender scene
get_viewport_screenshot — Review the result visually

Asset Library Workflow

search_polyhaven_assets — Search PolyHaven for free CC0 assets (HDRIs, textures, models)
download_polyhaven_asset — Download and import into Blender
Or: search_sketchfab_models → download_sketchfab_model for more variety
