Graphiti

The Graphiti MCP server provides AI assistants with access to a temporal knowledge graph system for storing, retrieving, and reasoning about relationships between entities. Built by Zep Software, this implementation uses Neo4j as its database backend and supports various LLM providers including OpenAI, Anthropic, and Google. The server exposes tools for adding episodes (conversations or documents), extracting entities and relationships, searching the graph with semantic and keyword matching, and retrieving facts with temporal context. It's particularly valuable for applications requiring persistent memory across conversations, such as tracking user preferences, documenting procedures, or maintaining factual relationships that change over time.
