GraphDB MCP Server
About
An MCP server that enables AI assistants to interact with GraphDB by executing SPARQL queries and retrieving database schemas. It is built for developers and knowledge workers who want to explore graph data through natural language interfaces.

- Execute SPARQL read queries against a GraphDB repository.
- Retrieve the ontology schema as RDF triples.
- Uses the Model Context Protocol for integration.
- Supports local GraphDB instances via HTTP.
