SCMCP

An MCP server for scRNA-Seq analysis with natural language!

🪩 What can it do?

  • IO module: Read and write scRNA-Seq data with natural language
  • Preprocessing module: Filtering, quality control, normalization, scaling, highly-variable genes, PCA, Neighbors,...
  • Tool module: Clustering, differential expression, etc.
  • Plotting module: Violin plots, heatmaps, dotplots
  • Cell-cell communication analysis
  • Pseudotime analysis
  • Enrichment analysis

❓ Who is this for?

  • Anyone who wants to do scRNA-Seq analysis using natural language!
  • Agent developers who want to call scanpy's functions for their applications

🌐 Where to use it?

You can use scmcp in most AI clients, plugins, or agent frameworks that support the MCP:

  • AI clients, like Cherry Studio
  • Plugins, like Cline
  • Agent frameworks, like Agno

🏎️ Quickstart

Install

Install from PyPI:

pip install scmcp

You can test it by running:

scmcp run

🚀 Running Modes

SCMCP provides two distinct run modes to accommodate different user needs and preferences:

1. Tool Mode

In tool mode, SCMCP provides a curated set of predefined functions that the LLM can select and execute.

Advantages:

  • Stable: Predefined functions ensure consistent and reliable execution
  • Predictable: Known behavior and expected outputs
  • Safe: Controlled environment with validated operations

Disadvantages:

  • Limited flexibility: Restricted to available predefined functions; you need to define new tools when you need customization functions

Usage

Running in terminal:

scmcp run --run-mode tool

Configure MCP client:

{
  "mcpServers": {
    "scmcp": {
      "command": "/home/test/bin/scmcp",
      "args": ["run", "--run-mode", "tool"]
    }
  }
}

Examples:

2. Code Mode

In code mode, SCMCP provides a Jupyter backend that allows the LLM to generate and execute custom code. Additionally, it can generate complete Jupyter notebooks containing executable code, analysis results, and visualizations.

This mode is based on the project: https://github.com/huang-sh/abcoder

Advantages:

  • Highly flexible: Can create custom workflows and combine operations freely
  • Extensible: Supports any Python code and external libraries
  • Interactive: Real-time code execution and debugging capabilities

Disadvantages:

  • Less stable: Code generation may vary each time

Usage

Running in terminal:

scmcp run --run-mode code

Configure MCP client:

{
  "mcpServers": {
    "scmcp": {
      "command": "/home/test/bin/scmcp",
      "args": ["run", "--run-mode", "code"]
    }
  }
}

🌐 Remote Deployment

For both modes, you can also run SCMCP remotely:

Remote Setup

Start the server:

# Tool mode
scmcp run --transport shttp --port 8000 --run-mode tool

# Code mode
scmcp run --transport shttp --port 8000 --run-mode code

Configure your MCP client:

{
  "mcpServers": {
    "scmcp": {
      "url": "http://localhost:8000/mcp"
    }
  }
}
