+# MCP Plugin README
+
+## Overview
+
+The MCP Plugin is a versatile tool designed to enhance the functionality of the Scanpy library, a popular toolkit for single-cell gene expression analysis. This plugin provides additional capabilities and optimizations for handling large datasets, performing complex analyses, and generating insightful visualizations. The MCP Plugin integrates seamlessly with Scanpy, offering users an extended range of tools and utilities to facilitate their research.
+
+## Installation
+
+To install the MCP Plugin, ensure that you have Python and pip installed on your system. The plugin can be installed via pip with the following command:
+
+```
+pip install mcp-plugin
+```
+
+Ensure that you have the required dependencies installed. The MCP Plugin requires the following packages:
+
+- numpy
+- scipy
+- pandas
+- matplotlib
+- h5py
+
+Optional dependencies for enhanced functionality include:
+
+- umap-learn
+- leidenalg
+
+## Usage
+
+Once installed, the MCP Plugin can be used in conjunction with Scanpy to perform a variety of tasks. Below are some basic usage examples:
+
+### Basic Usage
+
+To use the MCP Plugin, first import it alongside Scanpy in your Python script:
+
+```python
+import scanpy as sc
+import mcp_plugin as mcp
+```
+
+### Command-Line Interface
+
+The MCP Plugin provides a command-line interface (CLI) for executing tasks directly from the terminal. The CLI can be accessed using:
+
+```
+scanpy-cli
+```
+
+This command provides access to various tools and functionalities offered by the plugin.
+
+## Available Tool Endpoints
+
+The MCP Plugin extends Scanpy with several tool endpoints, including but not limited to:
+
+- **Preprocessing Tools**: Enhanced data normalization and scaling methods.
+- **Visualization Tools**: Advanced plotting capabilities for better data representation.
+- **Analysis Tools**: Improved clustering and dimensionality reduction techniques.
+
+For a complete list of available tools and their usage, refer to the plugin's documentation or use the help command in the CLI:
+
+```
+scanpy-cli --help
+```
+
+## Notes and Troubleshooting
+
+- **Compatibility**: Ensure that your version of Scanpy is compatible with the MCP Plugin. Check the plugin's documentation for version compatibility.
+- **Performance**: For large datasets, consider using the optional dependencies to improve performance and speed.
+- **Troubleshooting**: If you encounter issues, verify that all dependencies are correctly installed and up to date. Consult the plugin's GitHub repository for additional support and issue tracking.
+
+## Additional Resources
+
+For more information, visit the [Scanpy GitHub repository](https://github.com/scverse/scanpy) and explore the extensive documentation and community resources available. The MCP Plugin aims to complement Scanpy's capabilities, providing researchers with powerful tools for single-cell analysis.

+# Scanpy – Single-Cell Analysis in Python
+
+Scanpy is a scalable toolkit for analyzing single-cell gene expression data built jointly with [anndata][].
+It includes preprocessing, visualization, clustering, trajectory inference and differential expression testing.
+The Python-based implementation efficiently deals with datasets of more than one million cells.
+For datasets too large to fit into memory, [many scanpy functions][] are now compatible with [dask][] (**warning: experimental**).
+
+Discuss usage on the scverse [Discourse][]. Read the [documentation][].
+If you'd like to contribute by opening an issue or creating a pull request, please take a look at our [contribution guide][].

+# Scanpy Benchmarks
+
+This directory contains code for benchmarking Scanpy using [asv][].
+
+The functionality is checked using the [`benchmark.yml`][] workflow.
+Benchmarks are run using the [benchmark bot][].
+
+[asv]: https://asv.readthedocs.io/
+[`benchmark.yml`]: ../.github/workflows/benchmark.yml
+[benchmark bot]: https://github.com/apps/scverse-benchmark
+
+## Data processing in benchmarks
+
+Each dataset is processed so it has
+
+- `.layers['counts']` (containing data in C/row-major format) and `.layers['counts-off-axis']` (containing data in FORTRAN/column-major format)
+- `.X` and `.layers['off-axis']` with log-transformed data (formats like above)
+- a `.var['mt']` boolean column indicating mitochondrial genes
+
+The benchmarks are set up so the `layer` parameter indicates the layer that will be moved into `.X` before the benchmark.
+That way, we don’t need to add `layer=layer` everywhere.
