Best Neo4j MCP Servers
Neo4j is a graph database management system developed by Neo4j, Inc. It is a native graph database that stores data in nodes connected by relationships, providing an efficient way to query connected data.
Why this server?
Provides an optional Neo4j backend for storing and querying the code property graph, enabling graph database capabilities.
Why this server?
Allows interaction with a local Neo4j graph database containing PDBe-KB data, enabling read-only Cypher queries to explore molecular interactions and relationships in the Protein Data Bank.
