Overview

What is Neo4J MCP Server by CData?

Neo4J MCP Server by CData is a read-only Model Context Protocol (MCP) server that lets LLMs like Claude Desktop query live Neo4J data using natural language. It wraps the CData JDBC Driver for Neo4J, which exposes Neo4J as relational SQL models, so users can ask questions without writing SQL.

How to use Neo4J MCP Server by CData?

Clone the repository, build the JAR with mvn clean install, download and license the CData JDBC Driver for Neo4J, then create a .prp file with your JDBC connection string. Configure the server in Claude Desktop via claude_desktop_config.json or run it standalone with java -jar CDataMCP-jar-with-dependencies.jar <path>.prp. The server uses stdio transport and runs only on the same machine as the client.

Where does the data live?

Data resides in your Neo4J instance. The server does not store any data; it queries the live database on each request.

What transport does the server use?

It uses stdio transport, so it can only be used with clients running on the same machine as the server.

Does the server support authentication or OAuth?
