Overview

Neo4j's official MCP server lets agents query and mutate a graph database using Cypher over a bolt URI, with optional read-only mode. It authenticates with a Neo4j username and password. Cypher write access and connection credentials are the main security surface, mitigated by a configurable read-only flag.
