Blender Lab MCP Server

Officialby Blender Foundation (Blender Lab)freeverified Aug 11, 2026

Blender's own MCP server — natural-language access to the Blender Python API.

What it does

The Blender Foundation's first-party MCP server, built in Blender Lab and shipped as v1.0.0. An add-on inside Blender talks over a TCP socket to a standalone MCP server your client launches, exposing the Python API for scene analysis, data-block cleanup, geometry-node documentation, and debugging. Useful when you want to interrogate and repair a production file rather than generate one.

Connect

Connection is set up through the vendor's flow — follow the official connect instructions.

Local install: Two manual parts: drag-and-drop the mcp-1.0.0.zip add-on into Blender twice (first adds the https://lab.blender.org/ extension repository, then installs the add-on), then install the MCP server itself — either the .mcpb bundle from the releases page for clients that support it, or from source per the project's Setup wiki.

Auth: local-app — Requires Blender 5.1 or newer with the Blender Lab MCP add-on installed and enabled

Field notes

Official but experimental — a Blender Lab project, explicitly outside the current Blender roadmap. Blender's own docs carry a blunt security warning: the server 'will execute LLM generated code in Blender without any guards in place to protect your data from removal or being sent to a remote location', and they recommend running it in a virtual machine or on a system with no sensitive data. Three components must be downloaded and run manually (add-on, LLM client, MCP server); there is no one-line install. Blender 5.1+ only. The community ahujasid/blender-mcp is far easier to set up, works on 3.0+, and adds asset-library integrations this one has no equivalent for.
