# Dataset Viewer MCP Server

An MCP server for interacting with the [Hugging Face Dataset Viewer API](https://huggingface.co/docs/dataset-viewer), providing capabilities to browse and analyze datasets hosted on the Hugging Face Hub.

## Features

### Resources

- Uses `dataset://` URI scheme for accessing Hugging Face datasets

6. **search_dataset**
   - Search for text within a dataset
   - Parameters:
     - `dataset`: Dataset identifier
     - `config`: Configuration name
     - `split`: Split name
     - `query`: Text to search for
     - `auth_token` (optional): For private datasets

7. **filter**
   - Filter rows using SQL-like conditions
   - Parameters:
     - `dataset`: Dataset identifier
     - `config`: Configuration name
     - `split`: Split name
     - `where`: SQL WHERE clause (e.g. "score > 0.5")
     - `orderby` (optional): SQL ORDER BY clause
     - `page` (optional): Page number (0-based)
     - `auth_token` (optional): For private datasets

8. **get_parquet**
   - Download entire dataset in Parquet format
   - Parameters:
