cellpose-mcp 0.1.1

MCP server for AI-powered Cellpose cell segmentation via Model Context Protocol

Cellpose MCP Server

Cellpose-mcp is a Model Context Protocol (MCP) server that enables AI assistants like Claude, Cursor IDE, etc. to perform cell segmentation through natural language commands. This tool exposes comprehensive Cellpose functionality through 13+ MCP tools, including 2D/3D segmentation, batch processing, image restoration (denoising, deblurring, upsampling), and custom model training. The system integrates seamlessly with Napari, enabling complete workflows from segmentation to interactive visualization.

📌 Note: This project started as a fun project inspired by napari-mcp and adapted for Cellpose segmentation workflows. If you would like to contribute then please get in touch with me at [e-mail].

🚀 Quick Start

pip install cellpose-mcp

OR for development:

git clone https://github.com/surajinacademia/cellpose_mcp.git
cd cellpose_mcp
pip install -e .

Auto-Configure Your AI Application

Application	Installation Command	Notes
Cursor IDE	cellpose-mcp-install cursor	Auto-configures MCP settings
Claude Desktop	cellpose-mcp-install claude-desktop	Adds to Claude Desktop config
Antigravity	cellpose-mcp-install antigravity	Configures Antigravity MCP
Claude Code	cellpose-mcp-install claude-code	Or manually add .mcp.json to project root
VS Code	cellpose-mcp-install vscode	Configures Cline/Roo Cline extension

Manual Configuration for Claude Code

If you prefer manual setup, create a .mcp.json file in your project root:

{
  "mcpServers": {
    "cellpose": {
      "command": "python",
      "args": ["-m", "cellpose_mcp"],
      "env": {
        "KMP_DUPLICATE_LIB_OK": "TRUE",
        "OMP_NUM_THREADS": "1"
      }
    }
  }
}

After installation, restart your AI app and try asking:

"Can you list available Cellpose models?"
"Segment the cells in ./data/sample.tif using the cyto2 model"

🎯 What Can You Do?

Example: Cell Segmentation in Action

Original Image: Fluorescence microscopy with green-stained cytoplasm and blue-stained nuclei

Segmented Result: Cells automatically detected with boundaries and labels

Basic Cell Segmentation

"Segment the cells in ./data/sample.tif using the cyto2 model"
"List available Cellpose models"
"Estimate cell diameter from ./data/image.tif"

Advanced Workflows

"Segment all TIFF files in ./data/images/ and save masks to ./output/"
"Train a custom segmentation model using images in ./train/images/ and masks in ./train/masks/"
"Restore and segment the noisy image in ./data/noisy.tif using oneclick_cyto3"

Batch Processing

"Process all images in ./data/ with the cyto2 model and save results to ./output/"
