Memgraph Graph Database
In-memory graph database optimized for real-time analytics and streaming graph workloads. Memgraph uses Cypher (same as Neo4j), supports the Bolt protocol, and integrates with Kafka/Pulsar for streaming graph updates. MAGE (Memgraph Advanced Graph Extensions) provides graph algorithms and machine learning on graphs. Memgraph Cloud is the managed option. Strong focus on real-time graph analytics.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
BSL open-source core. TLS supported for Bolt connections. RBAC for user permissions. Self-hosted option for data control. SOC2 for Cloud. No auth by default is a concern — must be explicitly configured.
⚡ Reliability
Best When
You need real-time graph analytics and streaming graph ingestion with Cypher compatibility but need much higher performance than Neo4j on read-heavy workloads.
Avoid When
Your graph data exceeds available RAM, you need ACID transactions with high write rates, or you need Neo4j's specific plugin ecosystem.
Use Cases
- • Store and query knowledge graphs for agent RAG systems using Cypher — relationships between entities are first-class citizens
- • Build real-time graph analytics for agent decision systems — query community detection, shortest paths, and centrality metrics
- • Ingest streaming events (Kafka) into graph structure in real-time for agent situational awareness systems
- • Implement fraud detection and anomaly detection for AI agent platforms using graph traversal patterns
- • Run graph neural network algorithms via MAGE on knowledge graphs for agent recommendation features
Not For
- • OLTP transactional workloads with high write rates — Memgraph is optimized for read-heavy graph analytics
- • Large datasets that exceed RAM — Memgraph is in-memory; datasets must fit in server RAM (up to multi-TB with enterprise servers)
- • Teams already invested in Neo4j ecosystem — Neo4j has a larger plugin/driver ecosystem, though Memgraph is Bolt-compatible
Interface
Authentication
Username/password authentication via Bolt protocol. SSL/TLS for secure connections. Role-based access control for user permissions. No auth by default in local mode — must enable for production. Memgraph Cloud adds managed auth.
Pricing
Community edition is free but uses BSL (Business Source License) — check commercial use terms. Enterprise and Cloud have commercial pricing. MAGE algorithms are MIT licensed.

Known Gotchas
- ⚠ BSL license may restrict use in certain commercial contexts — verify license terms for your specific use case
- ⚠ In-memory architecture means data loss on restart without persistence configuration — enable disk persistence for production
- ⚠ Large traversals can cause memory spikes — implement query timeouts and memory limits for agent-submitted queries
- ⚠ Streaming ingestion via Kafka requires explicit Kafka consumer configuration in Memgraph
- ⚠ MAGE algorithms run in separate thread — long-running graph ML operations can block if memory is constrained
- ⚠ Cypher dialect is compatible with Neo4j but has small differences — test queries migrated from Neo4j explicitly
- ⚠ Default Memgraph port (7687 Bolt, 7444 HTTP) differs from Neo4j's defaults in some areas — verify driver configuration
