FAQ from Neo4j MCP Server
What operations does Neo4j MCP Server support?
It supports executing Cypher queries, creating nodes with labels and properties, and creating relationships between nodes.
What are the runtime requirements and dependencies?
A Neo4j database server, Python, and an MCP client. The service uses environment variables from a .env file for configuration.
Where is data stored after an operation?
Data is stored in the connected Neo4j database; this server does not persist data locally.
How is Neo4j MCP Server configured and authenticated?
Configure via environment variables: NEO4J_URI, NEO4J_USERNAME, NEO4J_PASSWORD. Optional HTTP_PROXY and HTTPS_PROXY environment variables are supported for proxy configuration. Authentication uses the Neo4j username and password.
What transport protocol does Neo4j MCP Server use?
It connects to a Neo4j server over HTTP (via the provided NEO4J_URI). Connections from the MCP client to this server likely use the Transport layer of the MCP framework. Optional HTTP/HTTPS proxy support is built in.
