blender-mcp

blender-mcp is a skill for Claude Code, Codex from cyborg-garden/hermes-agent-mt. It costs 17 tokens per session (1,431 once invoked), scanned A, a copy of blender-mcp, MIT.

A bridge between a coding agent and a running Blender 3D session, with instructions for using Blender's Python interface. It can work with scenes, objects, materials, animations, lighting, and renders through connected tools.

In plain words
What is it for?
Creating or changing 3D meshes, materials, animations, lighting, and rendered images in Blender.
Why use it?
It removes the need to manually perform Blender tasks through its user interface when the work can be scripted. A Blender session and the matching connection add-on are required.

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-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 11d 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.

The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Blender MCP Skill

Companion skill for the blender entry in the Hermes MCP catalog. The MCP server provides the connection to Blender; this skill teaches the bpy idioms and pitfalls for driving it well. It does not cover Blender UI workflows — everything here goes through the MCP tools against a live Blender session.

When to Use

Use when the user wants to create or modify anything in a running Blender instance: meshes, materials, animations, lighting, renders. Requires the blender MCP server installed and a Blender desktop session with the addon connected.

Prerequisites

  1. Install the MCP server from the Nous catalog (one-time):

    hermes mcp install blender
    

    This configures the pinned blender-mcp stdio server with the curated tool set: get_scene_info, get_object_info, get_viewport_screenshot, execute_blender_code.

  2. Install the addon inside Blender (one-time — the catalog entry's post-install notes cover this too):

  3. Every session: start Blender FIRST, press N in the viewport, open the "BlenderMCP" tab, click "Connect to Claude" (starts the local bridge socket). Then start your Hermes session so the MCP tools are loaded.

    The addon refuses to start under blender -b (background mode). On a machine without a display, run Blender under a virtual one: xvfb-run blender. GPU rendering works fine under Xvfb.

Quick Reference

MCP tool Use for
get_scene_info List objects before touching the scene
get_object_info Inspect one object (transform, materials)
get_viewport_screenshot Visual check of what you built
execute_blender_code Everything else — arbitrary bpy Python

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.
