### Description (declared)

# Blender MCP Server

Control Blender from any AI assistant using the [Model Context Protocol (MCP)](https://modelcontextprotocol.io).

27 tools across 7 namespaces — create objects, assign materials, render images, export scenes, execute Python scripts, manage async jobs, and more.

![Demo render — scene built entirely through MCP tools](docs/images/demo_render.png)

## How It Works

```
┌─────────────┐      stdio       ┌──────────────────┐    JSON/TCP     ┌─────────────────┐
│  MCP Client │ ◄──────────────► │  MCP Server      │ ◄─────────────► │  Blender Add-on │
│  (any host) │                  │  (Python)        │  localhost:9876 │  (runs in bpy)  │
└─────────────┘                  └──────────────────┘                 └─────────────────┘
```

1. The **Blender add-on** runs inside Blender and listens on `localhost:9876`.
2. The **MCP server** connects to your AI client via stdio and forwards tool calls to Blender over TCP.
3. You ask the AI → it calls MCP tools → Blender executes commands → results flow back.

## Quick Start

### 1. Install the MCP Server

```bash
git clone https://github.com/djeada/blender-mcp-server.git
cd blender-mcp-server
python3 -m venv .venv
source .venv/bin/activate
pip install -e .
```

This creates the executable `.venv/bin/blender-mcp-server`.

### 2. Install the Blender Add-on

Build the add-on zip:

```bash
./scripts/build_addon_zip.sh
```

Then in Blender:

1. Go to **Edit → Preferences → Add-ons → Install**.
2. Select `dist/blender_mcp_bridge.zip` and enable **Blender MCP Bridge**.
3. In the 3D Viewport, press **N** → open the **MCP** tab.
4. Confirm it shows **Listening on 127.0.0.1:9876**.

### 3. Connect Your MCP Client
