README
My first Model Context Protocol server for exploring datasets with LLMs using Python, pandas, and MCP.
Why this project?
This project is a beginner-friendly MCP server designed for AI engineers and data scientists who want to understand how LLMs can use external tools.
The server lets an MCP-compatible LLM client inspect and analyze a local CSV dataset.
What it does
MyFirstMCP exposes data science tools to an LLM client:
- List available datasets
- Profile a dataset
- Inspect numeric and categorical columns
- Preview rows
- Generate summary statistics
- Compute Pearson correlation
- Filter rows
- Count values in a column

Security notes
This project is intentionally limited for safety:
- It only reads CSV files.
- It only reads files from the local data/ directory.
- It does not execute arbitrary code.
- It does not run SQL.
- It limits preview sizes.
