What is GraphDB MCP Server?

This server is a Model Context Protocol (MCP) server designed to provide read-only access to an Ontotext GraphDB instance. It allows Language Learning Models (LLMs) to interact with and explore RDF graphs stored in GraphDB.

How to use GraphDB MCP Server?

To use this server, you need to configure it with your GraphDB endpoint, repository name, username, and password, either through environment variables or command-line arguments. Then, you can use the provided tools like sparqlQuery and listGraphs to interact with the data. The server also exposes various resources like Class List, Predicates, Statistics, Sample Data, and Graph Content for exploration.

FAQ from GraphDB MCP Server

What is GraphDB?

GraphDB is a semantic graph database that allows you to store and manage RDF data.

What is MCP?

MCP stands for Model Context Protocol, a protocol for LLMs to interact with external data sources.

How do I configure the server?

You can configure the server using environment variables or command-line arguments. See the Configuration section in the README.

What kind of SPARQL queries can I run?

You can run any read-only SPARQL query against the GraphDB repository.

How do I list all available graphs?

Use the listGraphs tool or access the Class List resource.
