Graphiti MCP Server
Graphiti MCP server enabling AI agents to build and query temporally-aware knowledge graphs — storing entities, relationships, and episodic memories with time-tracking, enabling agents to maintain long-term memory that understands how facts change over time, built on Neo4j and developed by Zep.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Neo4j + OpenAI credentials. HTTPS. Commercial project. Store secrets securely.
⚡ Reliability
Best When
An agent needs sophisticated long-term memory that tracks how facts change over time — particularly for agents operating over long periods where information evolves.
Avoid When
You need simple conversation memory — use lighter alternatives. Or if Neo4j infrastructure isn't available.
Use Cases
- • Building persistent agent memory with temporal awareness from long-running agents
- • Storing and querying entity relationships with time context from knowledge agents
- • Maintaining episodic memory of past conversations from conversational agents
- • Building knowledge graphs from structured and unstructured data from ingestion agents
- • Querying 'what was true at time T' from analytical agents
- • Agent memory systems that understand changing facts over time
Not For
- • Simple key-value or document storage (use simpler memory MCPs)
- • Teams without Neo4j infrastructure
- • Real-time streaming data (Graphiti is for episodic/semantic memory)
Interface
Authentication
Neo4j credentials required (URI, username, password). OpenAI API key required for embedding generation. Zep Cloud option available with Zep API key.
Pricing
Graphiti is open source. Requires Neo4j and OpenAI (or compatible LLM). Self-hosting is free minus infrastructure costs.
Agent Metadata
Known Gotchas
- ⚠ Requires Neo4j running — complex infrastructure dependency
- ⚠ OpenAI (or compatible) API key needed for embedding generation — adds cost
- ⚠ Temporal graph model has learning curve — agents need context to query effectively
- ⚠ From Zep (commercial company) — commercial cloud option available
- ⚠ Graphiti schema is opinionated — works best when used as designed
- ⚠ Knowledge graph quality depends on LLM extraction quality
