Blender Lab MCP Server

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

Caveats

  • Blender's own docs warn it executes LLM-generated code with no guards, and recommend a VM or a machine with no sensitive data.
  • Blender 5.1+ only, explicitly experimental and outside the current roadmap.
  • Three components must be downloaded and run manually; there is no one-line install.
  • The community blender server is far easier to set up, works on 3.0+, and adds asset-library integrations this one lacks.

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 alongside blend-file forensics: datablock inventories, missing-file and linked-library reports, viewport screenshots and thumbnail renders, and search over the Python API reference and the user manual. Useful when you want to interrogate and repair a production file rather than generate one.

Auth

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

Connect

Connect Blender Lab MCP Server to Claude Code

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.

Field notes

Full curator notes (verified Oct 10, 2026)

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, per the add-on's own blender_manifest.toml. v1.0.3 shipped 11 Sep 2026 (v1.0.2 three days earlier), 27 stars on projects.blender.org, last commit 29 Sep 2026 as of 10 Oct 2026, and half the 26 tools are duplicated as `*_for_cli` variants for headless use. Checked 10 Oct 2026 via the Forgejo API; both blender.org and the repo's web UI return 403 to automated fetchers, so the tool list comes from readme_tools.rst in the repo and the security quote is carried over from the last read of the docs page. 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.

Common questions

How do I install Blender Lab MCP?
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. Per-client setup is under Connect.
Does Blender Lab MCP need an API key?
No cloud key: it talks to the application running on your own machine, so that app has to be installed and open.
Is Blender Lab MCP official?
Yes, Blender Foundation (Blender Lab) maintains it. mcp.film last verified the listing on Oct 10, 2026.
