Why this level

  • The `execute_python` and `execute_script_file` tools run arbitrary code inside Blender, and the server edits scenes and project files.

Install

Manual install

codex plugin marketplace add dcc-mcp/dcc-mcp-agent-plugins

The first README command adds the DCC-MCP agent plugin for Codex, then `codex plugin add dcc-mcp@dcc-mcp`. The Blender add-on itself installs from a release ZIP or `pip install dcc-mcp-blender`.

Access and checks

How we review

Broad accessThe tool can change data, run commands or handle secrets.

  • The `execute_python` and `execute_script_file` tools run arbitrary code inside Blender, and the server edits scenes and project files.

This is third-party code. Review the repository files before installing.

What it does

`dcc-mcp-blender` embeds an MCP server inside the Blender process. Once the add-on is enabled, any MCP client calls tools over HTTP: primitive creation, face extrusion, bevels, boolean operations, UV unwrapping, material assignment, geometry nodes, animation, rigging, cameras and rendering. The README claims more than 200 ready tools grouped into over 25 skills. It installs as a Blender extension (a ZIP from the releases, Blender 4.5 or newer) or as a `pip` package. An agent can also read `install.md` and set up the dependencies itself. Service groups cover add-on development, scripting and running checks.

Who it is for. 3D artists and technical artists who want to drive a Blender scene with text commands and keep the result editable.

Good fit when

  • Scene must be built from primitives with bevels and booleans from a description
  • A model needs UV unwrapping and a checker pass to verify texture coordinates
  • Material and lighting are tuned in a live session and the render is reviewed at once
  • A Blender add-on is written and debugged while the agent reloads modules and runs checks

Not a fit when

  • Your Blender is older than 4.5, since the adapter rejects such builds at install time
  • An agent must not execute arbitrary code inside the Blender process
  • A one-off scene edit does not justify setting up an add-on and a server

Example request

Inspect the Blender scene, list its objects and propose a plan: read-only first, edits after my confirmation.

Authentication
not required

Environment variables

DCC_MCP_BLENDER_DISABLE_EXECUTE_PYTHON
Set to true to disable the `execute_python` and `execute_script_file` tools

Limitations

Blender 4.5 is the minimum; the author tested 4.5 LTS and 5.2 on Windows, Linux and macOS. Install through the Extensions menu, because the old Add-ons tab path does not work. Background tests do not prove GUI or GPU behavior, and gaps are listed in the coverage document. The `execute_python` and `execute_script_file` tools run arbitrary code in Blender; the `DCC_MCP_BLENDER_DISABLE_EXECUTE_PYTHON` variable turns them off. UI control needs a separate `dcc-cua`.

How to disable. Disable the extension in Blender preferences and remove the `blender` entry from the MCP client configuration. A `pip` install is removed with `pip uninstall dcc-mcp-blender`.

FAQ

How do I connect a client?

Add an entry with the address `http://127.0.0.1:9765/mcp` to the MCP client configuration, as in the README example for Claude Desktop. The server picks the port at start, so check it against the `dcc-mcp-cli list` output.

Which Blender version is needed?

Blender 4.5 or newer. The adapter rejects older builds at install time, and CI runs 4.5 LTS and 5.2.

How do I block arbitrary code execution?

Set `DCC_MCP_BLENDER_DISABLE_EXECUTE_PYTHON=true` to disable `execute_python` and `execute_script_file`. The `DCC_MCP_BLENDER_DISABLE_ARBITRARY_SCRIPT` variable closes every arbitrary script path.

How does it differ from `mcp-for-blender`?

Here the server runs inside Blender with no external process and exposes typed tools. `mcp-for-blender` relays over a socket and runs arbitrary Python by default.

Can I install with pip?

Yes, `pip install dcc-mcp-blender`, then call `dcc_mcp_blender.start_server()` in Blender's Python console. The README recommends the extension for everyday use.

README in short

The README covers extension and package installs, client connection, tools by group, environment variables and a comparison with `mcp-for-blender`. Separate showcases include a crate with PBR materials and a stylized reconstruction from a reference.
