OneMemory – self-hosted shared memory for AI agents over MCP (github.com)

OneMemory has been launched as a self-hosted memory store designed to facilitate communication between various AI agents—such as Claude Code, Claude Desktop, and Cursor—via Multi-Context Protocol (MCP) or standard REST API. This enables users to write a note on one device and retrieve it on another, creating a seamless experience across platforms. It operates on Node.js version 24 or newer, emphasizing lightweight deployment with just one SQLite file and three direct runtime dependencies. Key installation steps involve simple commands to set up the service locally. The significance of OneMemory lies in its potential to enhance the efficiency of AI systems by providing a shared and persistent memory that can be accessed from multiple devices. This not only improves collaboration among AI agents but also introduces robust features like a change feed for tracking notes, a memory linter to scan for secrets, and Markdown export functionalities for better data handling. The ability to manage scoped tokens further bolsters security, allowing users to control access levels. Overall, OneMemory represents a step forward in integrating AI agents' memory functions, empowering developers to build more cohesive and effective AI-driven applications.
