open-memory-std

Reference TypeScript implementation of the Open Memory Standard (OMS): a simple, backend-agnostic interface for storing, searching, updating, and deleting memory units.

This project includes:

• OMS types and store interface
• Reference adapters: in-memory, filesystem, SQLite, PostgreSQL, MongoDB, S3, and downstream API
• MCP server support (stdio + HTTP transport, optional auth)
• Contract, unit, and integration tests

Use this package as a baseline implementation, a test target for OMS-compatible backends, or a starting point for your own memory adapter.

Installation

Install the core package:

npm install open-memory

Store drivers are optional and only needed for the stores you use.

• In-memory, filesystem, downstream API: no extra driver packages
• SQLite store: npm install sqlite sqlite3
• PostgreSQL store: npm install pg
• MongoDB store: npm install mongodb
• S3 store: npm install @aws-sdk/client-s3
