Which integrations are available for this server?

Provides 27 tools for controlling Blender 3D, including scene manipulation, object creation and transformation, materials, modifiers, animation keyframing, rendering, and file import/export (FBX, OBJ, GLTF, USD).

How do I use Blender MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Blender MCP Server create a cube and add a subdivision surface modifier to it" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Blender MCP Server

A high-performance MCP (Model Context Protocol) server for controlling Blender 3D from AI agents like Claude Code.

Built with Rust + PyO3 for native Python integration.

Features

27 MCP tools for scene manipulation, materials, modifiers, animation, rendering
HTTP transport - works with any MCP client
Native Blender addon with GUI controls
Thread-safe architecture using channels
execute_python escape hatch for arbitrary bpy code

Quick Start

1. Install the wheel to Blender Python

# Build
cd C:\projects\projects.rust\_mcp\blender-mcp-rs
maturin build --release

# Install to Blender 5.0
& "C:\Programs\Blender5\5.0\python\bin\python.exe" -m pip install target\wheels\blender_mcp-0.1.0-cp311-cp311-win_amd64.whl --force-reinstall

2. Enable the addon in Blender

The addon is symlinked to Blender's addons folder. Enable it in: Edit > Preferences > Add-ons > Search "MCP Server"

Or via Python console:

import bpy
bpy.ops.preferences.addon_enable(module="mcp_server")

3. Start the server

Via GUI: Topbar > MCP > Start Server

Via Python:

bpy.ops.mcp.start(port=8765)

4. Connect Claude Code

Add to your MCP settings:

{
  "mcpServers": {
    "blender": {
      "url": "http://127.0.0.1:8765/mcp"
    }
  }
}

Architecture

Claude Code  <--HTTP-->  BlenderMcp (Rust)  <--Channel-->  Python Polling
                         (MCP + axum)                      (bpy.app.timers)
                              |
                              v
                        Blender Python (bpy)

Rust thread runs tokio + axum HTTP server
Crossbeam channels pass commands/responses
Python timer polls for commands, executes bpy, returns results
Graceful shutdown - no hangs on stop
