blender-agent

blender-agent is a skill for Claude Code, Codex from zavora-ai/computer-use-mcp. It costs 35 tokens per session (2,002 once invoked), scanned A, original, MIT.

A coding-agent skill for controlling Blender, a 3D creation application, through Blender's official MCP connection and computer control when no application interface is available.

In plain words
What is it for?
It is for working with Blender scenes and other in-app tasks through the available connection methods.
Why use it?
It gives the agent a defined way to choose between Blender's programmatic interface and computer control.

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.

Security

Grade A, and why

blender-agent 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Driving Blender with two MCP servers

Blender needs both servers, but they are not interchangeable. Route by capability, not by habit.

Setup gotchas that cost the most time

These were all found by running it, and each produces a misleading error.

Blender's "Allow Online Access" must be on. The addon's register() silently refuses to start its server when bpy.app.online_access is false, and every Blender tool then fails with Cannot connect to Blender at localhost:9876, which reads like the addon is missing. It is not. Enable it once:

bpy.context.preferences.system.use_online_access = True
bpy.context.preferences.addons['bl_ext.user_default.mcp'].preferences.use_autostart = True
bpy.ops.wm.save_userpref()

With both set, a GUI launch has the socket listening in about two seconds — no clicking through Preferences, and no sidebar panel.

The official and community servers share the name blender-mcp. uvx blender-mcp installs the community package from PyPI. The official Blender Lab server has to come from projects.blender.org/lab/blender_mcp and be invoked by path. They also default to the same port, 9876, so run only one.

get_screenshot_of_window_as_image needs a small size_limit_in_bytes. At v1.0.2 it returns an image at 20 KB and 100 KB, and fails above that with Invalid response from Blender … Unterminated string, which is a framing bug, not a permissions problem. get_screenshot_of_area_as_image works fine — prefer it, since one area is what you usually want anyway.

Render paths are sandboxed to a basename. render_thumbnail_to_path and render_viewport_to_path discard the directory you pass and write into Blender's per-session temp directory. Read the filepath out of the result rather than assuming your own path was used.

Never start a heavy render inside execute_blender_code. A Cycles GPU render launched through the addon's socket starved it and took the whole Blender process down — the tool returned Empty response from Blender, then Cannot connect, and the process was gone with the unsaved scene. Blender's addon server answers synchronously on the main thread, so anything that blocks for tens of seconds is a hazard.

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.

blender-agent is a skill published in the GitHub repository zavora-ai/computer-use-mcp (52 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 2,002 once invoked, about $0.0002 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 2026-09-12.
