# LocalData MCP

A data science plugin for LLM agents. Connects to 13 database types, 20+ file formats, graph and RDF sources, and provides 8 analytical domains through 52 MCP tools.

LocalData MCP gives LLM agents direct access to local and remote data sources through the [Model Context Protocol](https://modelcontextprotocol.io/). Beyond data connectivity, it provides a full data science toolkit: statistical analysis, time series forecasting, regression modeling, clustering, business intelligence, geospatial analysis, optimization, and sampling methods — all designed for LLM-driven workflows with composition metadata and progressive disclosure.
