Overview

Data Exploration MCP Server

An MCP server that turns a local CSV file into a conversational data-exploration assistant in Claude Desktop, via a load-csv tool, a run-script tool, and an explore-data prompt template. Use it for conversational exploration of a local CSV file, not for live database connections or BI dashboards.

What it does

MCP Server for Data Exploration acts as a personal data-scientist assistant, turning a local CSV dataset into clear, actionable insights through an interactive Claude Desktop conversation. It exposes an explore-data prompt template tailored for data-exploration tasks, taking a csv_path (local path to the CSV file) and a topic (the exploration focus, for example "Weather patterns in New York" or "Housing prices in California") as the starting inputs.

When to use - and when NOT to

Use it when you want to explore a local CSV dataset conversationally in Claude Desktop - loading it, running analysis scripts, and getting a topic-focused summary. Two worked case studies illustrate this at scale: a 2,226,382-row (178.9 MB) USA real-estate Kaggle dataset explored for California housing-price trends, and a 2,836,186-row (169.3 MB) UK daily-weather Kaggle dataset explored for London temperature, humidity, and wind patterns, producing a written report plus separate temperature-trend, temperature-humidity-by-season, and wind-direction-by-season graphs. It is not a general-purpose data-warehouse or BI connector - it works against a local CSV file passed by path, not a live database connection.

Capabilities

Two tools back the exploration flow: load-csv (loads a CSV file into a DataFrame, taking a required csv_path and an optional df_name that defaults to df_1, df_2, and so on) and run-script (executes an arbitrary Python script against the loaded data, taking a required script argument). Together with the explore-data prompt template, this lets Claude load a dataset once and then iteratively run whatever analysis script the conversation calls for. The server can be registered in Claude Desktop's config either as an unpublished local build (pointing uv --directory at the project's source path) or as a published package (uvx mcp-server-ds); the config file lives at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%/Claude/claude_desktop_config.json on Windows. For development, dependencies are synced with uv sync, distributions are built with uv build into the dist/ directory, and releases are published to PyPI with uv publish. The project is released under the MIT License.

How to install

python setup.py

Who it's for

Data scientists, analysts, and developers who want to explore a CSV dataset conversationally in Claude Desktop without writing their own analysis pipeline from scratch. It is maintained as an open-source project by ReadingPlus.AI LLC and open to community contributions - bug reports are asked to include steps to reproduce, expected versus actual behavior, and screenshots or error logs where relevant.
