Overview

What is Oxigraph MCP Server?

A Model Context Protocol (MCP) server that provides direct access to PyOxigraph functionality through the MCP protocol, enabling RDF and SPARQL capabilities from any MCP client.

How to use Oxigraph MCP Server?

Install with pip install mcp-server-oxigraph or uv pip install mcp-server-oxigraph. Configure Claude Desktop by adding a JSON entry with command uv run oxigraph-mcp and environment variable PYTHONUNBUFFERED=1. Then use tools like oxigraph_create_store, oxigraph_query, and oxigraph_add to work with RDF data.

Key features of Oxigraph MCP Server

  • Store management: create, open, close, list RDF stores
  • RDF Data Model: create nodes, literals, quads
  • SPARQL operations: execute queries and updates
  • Serialization: parse and serialize RDF in various formats
  • Knowledge Graph API for demonstration purposes

Use cases of Oxigraph MCP Server

  • Add RDF triples to a store and query them with SPARQL
  • Manage multiple in‑memory or file‑based RDF stores
  • Demonstrate higher‑level knowledge graph operations
  • Integrate RDF data handling into MCP‑compatible assistants
