### Description (declared)

# Oxigraph MCP Server

A Model Context Protocol (MCP) server for [Oxigraph](https://github.com/oxigraph/oxigraph), a fast and lightweight RDF triple store with SPARQL support.

Oxigraph is a high-performance in-memory or file-based RDF graph database written in Rust. This MCP server provides a Claude-friendly wrapper for accessing PyOxigraph (the Python bindings for Oxigraph) through the Model Context Protocol.

## Quickstart

### Installation

```bash
uv pip install mcp-server-oxigraph
```

### Minimal Claude Desktop Configuration

Add the following to your Claude Desktop MCP configuration:

```json
"oxigraph": {
  "command": "uv",
  "args": ["run", "mcp-server-oxigraph"],
  "env": {}
}
```

### Setting a Default Database (Optional)

To set a specific default database location, add the `OXIGRAPH_DEFAULT_STORE` environment variable:

```json
"oxigraph": {
  "command": "uv",
  "args": ["run", "mcp-server-oxigraph"],
  "env": {
    "OXIGRAPH_DEFAULT_STORE": "~/.claude/my_knowledge_graph.oxigraph"
  }
}
```

## Why Use Oxigraph MCP?

Oxigraph MCP is ideal for:

- **Quickly building knowledge bases**: Store structured information in a queryable graph database
- **Prototyping semantic applications**: Test data models and queries interactively
- **Schema development**: Design and test RDF schemas and ontologies
- **Local data storage**: Maintain persistent data without external services
- **SPARQL exploration**: Experiment with complex SPARQL queries in an interactive environment

## Features

This MCP server provides:

- **Direct PyOxigraph access**: Clean, stateless wrapper for PyOxigraph functionality
- **Multiple store management**: Create, open, and manage multiple file-based stores
- **Comprehensive RDF support**: Work with all core RDF data types and operations
- **Full SPARQL implementation**: Execute queries and updates with properly structured results
- **Rich serialization options**: Support for all major RDF formats
