Ratary Overview

The ontorata/ratary MCP server gives AI assistants persistent, structured memory through MCP tools. It stores versioned, owner-scoped knowledge and supports hybrid retrieval, metadata, relationships, graph traversal, and bounded context assembly. Run the server locally with a SQL metadata store, or connect the npm MCP package to a Ratary API using environment variables. Reach for it when coding assistants or agents need memory across sessions and projects.
