## Description

GraphDB MCP Server provides read-only access to Ontotext GraphDB repositories, enabling LLMs to explore RDF graphs and execute SPARQL queries. The server exposes tools for running SPARQL queries and listing graphs, along with resources that provide structured views of repository data including class lists, predicates, statistics, and sample data. Built with TypeScript using the Model Context Protocol SDK, it supports authentication, custom query formats, and graph-specific operations, making it particularly valuable for AI assistants that need to analyze semantic data stored in RDF triple stores without switching contexts.
