What is Model Context Protocol (MCP)?

MCP is a standardized protocol that allows you to interact with large language models (LLMs) and external systems (such as Neo4j) through natural language. This enables you to easily perform database queries, manage cloud instances, and store personal knowledge graphs.

How to use MCP?

Through simple natural language input, you can easily create graphs, execute Cypher queries, manage Neo4j Aura instances, etc. There's no need to write complex code; just tell MCP your requirements.

Applicable Scenarios

MCP is very suitable for users who need to quickly access database information, automate task processing, and build personal knowledge graphs.

Main Features

Natural Language to Cypher QueryConvert natural language into Cypher query statements for querying and operating Neo4j databases.

Personal Knowledge Graph ManagementStore and retrieve entities and relationships in local or remote Neo4j instances, supporting data access across sessions and clients.

Neo4j Aura Cloud Service ManagementCreate, destroy, scale, or enable Neo4j Aura instances directly from the AI assistant chat interface.

Advantages and Limitations

Advantages

Simplify the database operation process

Support cross - platform collaboration

Reduce the need for manual coding

Limitations

There may be a certain learning curve for advanced features

Some advanced configurations still require manual intervention

How to Use

Install the MCP Client

Download and install a client that supports the MCP protocol (such as the VS Code plugin or the Cursor application).

Connect to a Neo4j Instance

Configure the client to connect to your Neo4j database or Neo4j Aura cloud service.

Send Natural Language Instructions

Enter natural language instructions, such as 'Show the sales trend for the last three months'.

Usage Examples

Generate a Product Sales Statistics ChartGenerate a bar chart based on product sales frequency, total sales volume, and average sales volume.

Create a Neo4j Aura InstanceCreate a new instance named'mcp - test' on Neo4j Aura.

🚀 Neo4j MCP Client and Server

The Neo4j MCP Client and Server provide a standardized way to manage context between large - language models and external systems, enabling seamless interaction with Neo4j.

🚀 Quick Start

The Model Context Protocol (MCP) is a standardized protocol for managing context between Large Language Models (LLMs) and external systems. This allows you to use Claude Desktop or any other MCP client (e.g., VS Code, Cursor, Windsurf) to interact with Neo4j and your Aura account through natural language, such as:

What's in my graph?
Render a chart showing the best - selling products sorted by frequency, sum, and average volume.
List my instances.
Create a new instance named mcp - test, configured as Aura Professional with 4GB of memory and enable the Graph Data Science feature.
Store the fact that I worked on the Neo4j MCP server with Andreas and Oskar today.

✨ Features

Servers

`mcp - neo4j - cypher` - Natural Language to Cypher Query Conversion

[See Readme for details](./servers/mcp - neo4j - cypher/)

Fetch the database schema and execute generated read and write Cypher queries against the specified database.

`mcp - neo4j - memory` - Knowledge Graph Memory Stored in Neo4j

[See Readme for details](./servers/mcp - neo4j - memory/)
