Zep

Zep is a context engineering platform for AI agents. It builds and maintains a temporal knowledge graph from chat histories and business data, then retrieves and assembles only the most relevant context for each request. This improves accuracy and personalization while reducing hallucinations and token spend. Zep includes agent memory, Graph RAG, and context assembly services with managed cloud APIs and SDKs for Python, TypeScript/JavaScript, and Go. Developers can ingest messages and structured/unstructured records, define custom entity/edge types, and query or retrieve subgraphs on demand. Zep also ships an experimental Knowledge Graph MCP Server so MCP clients like Claude Desktop or Cursor can persist and recall context locally or against Zep Cloud. Enterprise options add SOC 2 Type II, HIPAA BAA, audit logs, SSO, SLA, and BYOC/VPC deployment.
