mcp-slicer 0.1.2

A MCP server for 3D Slicer

MCP-Slicer - 3D Slicer Model Context Protocol Integration

English | 简体中文

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

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

brew install uv

On Windows

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

and then

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

Otherwise installation instructions are on their website: Install uv

⚠️ Please install UV first

Claude for Desktop Integration

Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json to include the following:

{
  "mcpServers": {
    "slicer": {
      "command": "uvx",
      "args": ["mcp-slicer"]
    }
  }
}

Cline Intergration

{
  "mcpServers": {
    "slicer": {
      "command": "uvx",
      "args": ["mcp-slicer"]
    }
  }
}

Usage

Open Slicer Web Server

First, open the Slicer Web Server module, ensure the required interfaces are checked, then start the server

Technical Details

Utilizes existing Slicer Web Server interfaces. For technical details, please see Slicer web server user guide

Limitations & Security Considerations

• The execute_python_code tool allows running arbitrary Python code in 3D Slicer, which is powerful but potentially dangerous.

  ⚠️ Not recommended for production use.

• Complex operations may need to be broken down into smaller steps.
