What is zmem MCP Memory Server?

zmem MCP Memory Server is a TypeScript-based Model Context Protocol (MCP) server that enables project-specific and knowledge graph-based memory for Claude, LLM agents, and other tools. It supports storing, retrieving, and managing entities, relations, and observations per project, with a focus on flexibility and cross-project knowledge sharing.

How to use zmem MCP Memory Server?

To use zmem, add it to your MCP configuration (e.g., for Windsurf) with the command and path to the built index. Install dependencies, build, and run via npm or Docker. Use the MCP client to call tools such as save_project_observations with a project ID and observations. Persisted memory files are stored in a configurable directory (default /app/memories).
