+# sktime MCP (Model Context Protocol) Service
+
+## Project Introduction
+
+sktime is a unified framework for machine learning with time series data. It provides a comprehensive suite of tools and algorithms for forecasting, classification, regression, clustering, and transformations. The framework is designed to be modular and extensible, allowing developers to build complex machine learning pipelines with ease. Core functionalities include base classes for forecasters, classifiers, and transformers, ensuring a consistent interface across different time series learning tasks.
+
+## Installation Method
+
+To install sktime, ensure you have Python installed and then use pip to install the package along with its dependencies:
+
+- Required dependencies: numpy, pandas, scikit-learn
+- Optional dependencies for extended functionalities: matplotlib, tensorflow
+
+Install sktime using pip:
+
+pip install sktime
+
+## Quick Start
+
+Here's a quick example of how to use sktime for a simple forecasting task:
+
+1. Import the necessary modules:
+
+from sktime.forecasting.model_selection import temporal_train_test_split
+from sktime.forecasting.arima import AutoARIMA
+from sktime.performance_metrics.forecasting import mean_absolute_percentage_error
+
+2. Load your time series data and split it into training and testing sets:
+
+y_train, y_test = temporal_train_test_split(y)
+
+3. Initialize and fit a forecaster:
+
+forecaster = AutoARIMA()
+forecaster.fit(y_train)
+
+4. Make predictions and evaluate:
+
+y_pred = forecaster.predict(fh=len(y_test))
+mape = mean_absolute_percentage_error(y_test, y_pred)
+
+## Available Tools and Endpoints List
+
+- **BaseForecaster**: Core forecasting functionalities including methods for fitting and predicting time series data.
+- **BaseClassifier**: Core classification functionalities including methods for fitting and predicting classification tasks.
+- **BaseTransformer**: Core transformation functionalities including methods for transforming time series data.
+- **sktime-forecast**: Command-line interface for running forecasting models on time series data.
+
+## Common Issues and Notes
+
+- Ensure all required dependencies are installed to avoid import errors.
+- For optimal performance, consider using optional dependencies like tensorflow for deep learning models.
+- The framework is designed to handle various time series formats, but ensure your data is preprocessed correctly to match expected input types.
+
+## Reference Links or Documentation
+
+For more detailed information, visit the [sktime GitHub repository](https://github.com/sktime/sktime) and the [official documentation](https://www.sktime.org/en/stable/). These resources provide comprehensive guides on system architecture, core components, and usage examples.

+> A unified interface for machine learning with time series
+
+:rocket: **Version 0.40.1 out now!** [Check out the release notes here](https://www.sktime.net/en/latest/changelog.html).
+
+sktime is a library for time series analysis in Python. It provides a unified interface for multiple time series learning tasks. Currently, this includes forecasting, time series classification, clustering, anomaly/changepoint detection, and other tasks. It comes with [time series algorithms](https://www.sktime.net/en/stable/estimator_overview.html) and [scikit-learn] compatible tools to build, tune, and validate time series models.

+## :dizzy: Features
+Our objective is to enhance the interoperability and usability of the time series analysis ecosystem in its entirety. sktime provides a __unified interface for distinct but related time series learning tasks__. It features [__dedicated time series algorithms__](https://www.sktime.net/en/stable/estimator_overview.html) and __tools for composite model building__,  such as pipelining, ensembling, tuning, and reduction, empowering users to apply algorithms designed for one task to another.
+
+sktime also provides **interfaces to related libraries**, for example [scikit-learn], [statsmodels], [tsfresh], [PyOD], and [fbprophet], among others.

+
+### pip
+Using pip, sktime releases are available as source packages and binary wheels.
+Available wheels are listed [here](https://pypi.org/simple/sktime/).
+
+```bash
+pip install sktime
+```
+
+or, with maximum dependencies,
+
+```bash
+pip install sktime[all_extras]
+```
+
+For curated sets of soft dependencies for specific learning tasks:
+
+```bash
+pip install sktime[forecasting]  # for selected forecasting dependencies
+pip install sktime[forecasting,transformations]  # forecasters and transformers
+```
+
+or similar. Valid sets are:
+
+* `forecasting`
+* `transformations`
+* `classification`
+* `regression`
+* `clustering`
+* `param_est`
+* `networks`
+* `detection`
+* `alignment`
+
+Cave: in general, not all soft dependencies for a learning task are installed,
+only a curated selection.
+
+### conda
+You can also install sktime from `conda` via the `conda-forge` channel.
+The feedstock including the build recipe and configuration is maintained
+in [this conda-forge repository](https://github.com/conda-forge/sktime-feedstock).
+
+```bash
+conda install -c conda-forge sktime
+```
+
+or, with maximum dependencies,
+
+```bash
+conda install -c conda-forge sktime-all-extras
+```
+
+(as `conda` does not support dependency sets,
+flexible choice of soft dependencies is unavailable via `conda`)
+
+## :zap: Quickstart
+
+### Forecasting
+
+``` python
+from sktime.datasets import load_airline
+from sktime.forecasting.base import ForecastingHorizon
+from sktime.forecasting.theta import ThetaForecaster
+from sktime.split import temporal_train_test_split
+from sktime.performance_metrics.forecasting import mean_absolute_percentage_error
+
+y = load_airline()
+y_train, y_test = temporal_train_test_split(y)
+fh = ForecastingHorizon(y_test.index, is_relative=False)
+forecaster = ThetaForecaster(sp=12)  # monthly seasonal periodicity
+forecaster.fit(y_train)
+y_pred = forecaster.predict(fh)
+mean_absolute_percentage_error(y_test, y_pred)
+>>> 0.08661467738190656
+```
+
+### Time Series Classification
+
+```python
+from sktime.classification.interval_based import TimeSeriesForestClassifier
+from sktime.datasets import load_arrow_head
+from sklearn.model_selection import train_test_split
+from sklearn.metrics import accuracy_score
+
+X, y = load_arrow_head()
+X_train, X_test, y_train, y_test = train_test_split(X, y)
+classifier = TimeSeriesForestClassifier()
+classifier.fit(X_train, y_train)
+y_pred = classifier.predict(X_test)
+accuracy_score(y_test, y_pred)
+>>> 0.8679245283018868
