RDF Explorer
Summary
RDF Explorer is an MCP server that provides a conversational interface for exploring and analyzing RDF-based Knowledge Graphs in either Local File mode or SPARQL Endpoint mode. Developed by Emeka Azuka Okoye, it facilitates communication between AI applications and RDF data through SPARQL queries, full-text search, and graph statistics tools. The server supports both local RDF files and external SPARQL endpoints, offering features like schema exploration, relationship discovery, and graph visualization. Particularly useful for knowledge graph research, semantic web exploration, and AI data preparation workflows where structured graph data needs to be queried conversationally.
