It uses the Cypher query language for expressing graph traversals, pattern matching, and aggregations. Neo4j exposes data via the Bolt binary protocol (used by all official drivers), an HTTP API for Cypher execution, and a REST Discovery API. It is available as Community Edition (open source), Enterprise Edition, and Neo4j Aura (fully managed cloud). A suite of four community-maintained MCP servers (from Neo4j Labs) enables AI agents to query, model, and manage graph data via natural language.","best_when":"Your data is fundamentally relational — fraud networks, knowledge graphs, recommendation graphs, org charts — where traversing relationships is the primary query pattern.","avoid_when":"Your data is tabular with few meaningful relationships, or you need sub-millisecond OLAP aggregations over billions of rows.","last_evaluated":"2026-03-01T09:50:05.987729+00:00"}
