MCP-Slicer connects 3D Slicer with model clients like Claude Desktop or Cline through the Model Context Protocol (MCP), enabling direct interaction and control of 3D Slicer. This integration allows for medical image processing, scene creation, and manipulation using natural language.

## Features

1. **list_nodes**: List and filter Slicer MRML nodes and view their properties

2. **execute_python_code**: Execute Python code in the Slicer environment

3. **capture_screenshot**: Capture real-time screenshots of Slicer views
   - Full application window (including module panels)
   - Individual slice views (Red/Yellow/Green)
   - 3D rendering view
   - Enables complete REACT loop with visual feedback

## Installation

### Prerequisites

- 3D Slicer 5.8 or newer
- Python 3.13 or newer
- uv package manager

**If you're on Mac, please install uv as**

```bash
brew install uv
```

**On Windows**

```bash
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
```

and then

```bash
set Path=C:\Users\nntra\.local\bin;%Path%
```

Otherwise installation instructions are on their website: [Install uv](https://docs.astral.sh/uv/getting-started/installation/)

**⚠️ Please install UV first**
