About
Cognee is an open memory engine you run yourself that gives your agent a lasting memory. It pulls together vector search, knowledge graphs, and ordinary relational storage into one system, so your agent can remember facts, relationships, and history. An MCP server is included, so any compatible agent can read and write memory without custom glue.
