Blender Lab MCP Server — guide skill for 3D scenes

For AI agents: find the right skill in one call — curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>" returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the how-to page. From a terminal: curl -fsSL https://varg.ai/install | sh installs the vargai CLI (https://varg.ai/how-to/cli.md): vargai search and vargai install <slug> with no key, every varg model after vargai login.

Blender's official MCP server: query and edit open scenes with Blender Python, bundled API docs and screenshots.

What it does

The Blender Foundation's lightweight MCP server from Blender Lab, for Blender 5.1 and newer. An add-on opens a local socket in Blender, and the server gives any stdio or HTTP MCP client tools to run Blender Python (execute_blender_code), summarise data-blocks, missing files, linked libraries and objects, search the bundled Python API reference and manual, and take window or area screenshots. Blender's own examples are scene analysis and clean-up: polygon outliers in the Classroom benchmark scene, fixing data-block names, documenting a Geometry Nodes setup. It is the official option next to the community blender-mcp, and it also targets local models through llama.cpp. Blender warns that it runs model-written code with no guards: use a virtual machine or a system without sensitive data.

Use when

• ask questions about an open .blend file in plain language
• find heavy objects, bad normals or missing files in a scene
• rename, document or tidy data-blocks and Geometry Nodes setups
• let an agent run Blender Python through the official add-on
• use Blender with a local LLM through llama.cpp

Not for

• Machines with sensitive data: Blender recommends a virtual machine
• Asset search or AI 3D generation: blender-mcp adds Poly Haven, Sketchfab and generators
• Blender 5.0 or older

Install

• Any MCP client: cd $HOME && git clone https://projects.blender.org/lab/blender_mcp.git && uv --directory $HOME/blender_mcp/mcp run blender-mcp
• Any agent, with the vargai CLI: vargai install blender-lab-mcp

• Turn a browser game into a cinematic trailer: Record the browser game your agent built frame-exact, script shots and cameras, then cut a 1080p trailer on the beat.
• Meshy 3D Generation: Meshy's official skill: text or image to a textured 3D model, then remesh, rig, animate and export it as GLB or FBX.
