Blender MCP

Overview

Blender MCP is an open-source Model Context Protocol server that lets AI assistants control Blender through natural language. It works with any MCP-compatible client — Cursor, Windsurf, Claude Desktop, and more.

The project consists of two components:

• MCP Server (src/blender_mcp/) — a FastMCP server exposing Blender operations as MCP tools

• Blender Addon (addon/blender_mcp_addon/) — a Blender plugin that receives commands over TCP and executes them via Blender's Python API

AI Client (Cursor / Windsurf / Claude Desktop)
    ↓  MCP protocol (stdio or HTTP)
Blender MCP Server (Python, FastMCP)
    ↓  TCP JSON messages (localhost:9876)
Blender Addon (runs inside Blender)
    ↓  Blender Python API (bpy)

All renders below were generated entirely through AI commands using Blender MCP — no manual Blender interaction.

Key Features

• 359 MCP tools across 51 modules — modeling, materials, animation, rendering, rigging, and more

• Smart skill loading — default skill profile starts with 32 tools; 12 skill groups activate on demand to keep AI context lean

• 6 profiles — from minimal (29 tools) to full (356 tools)

• Visual feedback — blender_snapshot_viewport and blender_snapshot_render_preview for multimodal AI review loops

• Checkpoint system — named save/restore points before risky operations

• Style system — 8 rendering style presets from Pixel Art to AAA

• 67 procedural materials — metals, woods, stones, fabrics, nature, skin, effects, toon

• Quality audit — topology, UV, and performance validation

• Blender 4.x / 5.x compatible

• Multi-IDE support — Cursor, Windsurf, Claude Desktop, and any MCP client

Quick Start

Prerequisites

• Python 3.10+

• Blender 4.0+

• uv (recommended) or pip

• An MCP-compatible client

Install & Run

git clone https://github.com/harveyxiacn/blender-mcp.git
cd blender-mcp
uv sync

# Build the Blender addon
python build_addon.py

# Start the MCP server
uv run blender-mcp

Or install from PyPI:

pip install blender-mcp
blender-mcp

Set Up Blender

1. Open Blender → Edit → Preferences → Add-ons → Install...

2. Select dist/blender_mcp_addon.zip

3. Enable Blender MCP

4. Open the MCP panel in the 3D View sidebar

Configure Your IDE

Add to your MCP client config:

{
  "mcpServers": {
    "blender": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/blender-mcp", "blender-mcp"]
    }
  }
}

Tool Profiles

Skill System

With the default skill profile, only core tools load at startup. AI activates additional groups on demand:

blender_list_skills         → see all 12 available skill groups
blender_activate_skill      → load a group's tools dynamically
blender_deactivate_skill    → unload to free AI context

Skills include: modeling, materials, style, character, animation, scene_setup, automation, physics, batch_assets, advanced_3d, sport_character, training.

概述

Blender MCP 是一个开源的 Model Context Protocol 服务器，让 AI 助手可以通过自然语言控制 Blender。支持 Cursor、Windsurf、Claude Desktop 等任意 MCP 兼容客户端。

展示

以下所有渲染结果完全通过 AI 命令生成，无需手动操作 Blender。

核心特性

• 359 个 MCP 工具，覆盖建模、材质、动画、渲染等全流程

• 智能工具加载 — 默认 skill 配置仅加载 32 个工具，12 个技能组按需激活

• 6 种配置方案 — 从 minimal（29 个工具）到 full（356 个工具）

• 视觉反馈 — 视口截图 + 渲染预览，支持多模态 AI 审查循环

• 检查点系统 — 高风险操作前的命名存档/还原点

• 风格系统 — 8 种渲染风格预设（像素风到 3A 级）

• 67 种程序化材质 — 金属、木材、石材、布料、自然、皮肤、特效、卡通

• 质量审计 — 拓扑、UV、性能验证

• 兼容 Blender 4.x / 5.x

快速开始

git clone https://github.com/harveyxiacn/blender-mcp.git
cd blender-mcp
uv sync

# 打包 Blender 插件
python build_addon.py

# 启动 MCP 服务器
uv run blender-mcp

或通过 pip 安装：

pip install blender-mcp
blender-mcp

然后在 Blender 中：

1. 编辑 → 偏好设置 → 插件 → 安装...

2. 选择 dist/blender_mcp_addon.zip

3. 启用 Blender MCP

4. 在 3D 视图侧边栏打开 MCP 面板
