### Description (declared)

# Neo4j GraphRAG MCP Server

[![PyPI version](https://badge.fury.io/py/mcp-neo4j-graphrag.svg)](https://pypi.org/project/mcp-neo4j-graphrag/)
[![Python 3.10+](https://img.shields.io/badge/python-3.10+-blue.svg)](https://www.python.org/downloads/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)

An MCP server that extends Neo4j with **vector search**, **fulltext search**, **search-augmented Cypher queries**, **write operations**, and **multimodal image retrieval** for GraphRAG applications.

> **Inspired by** the [Neo4j Labs `mcp-neo4j-cypher`](https://github.com/neo4j-contrib/mcp-neo4j/tree/main/servers/mcp-neo4j-cypher) server. This server adds vector search, fulltext search, and the innovative `search_cypher_query` tool for combining search with graph traversal.

## Overview

This server enables LLMs to:
- 🔍 Search Neo4j vector indexes using semantic similarity
- 📝 Search fulltext indexes with Lucene syntax
- ⚡ Combine search with Cypher queries via `search_cypher_query`
- 🕸️ Execute read-only Cypher queries
- ✏️ Execute write Cypher queries (CREATE, MERGE, SET, DELETE)
- 🖼️ Retrieve images stored in Neo4j nodes (multimodal — returns the image directly to the LLM)

Built on [LiteLLM](https://docs.litellm.ai/) for multi-provider embedding support (OpenAI, Azure, Bedrock, Cohere, etc.).
