Memento

Memento is a local-first MCP (Model Context Protocol) server that provides persistent memory and knowledge graph capabilities for AI assistant clients. It integrates with any MCP-compatible tool (such as Claude, Cursor, Windsurf, and more) to give AI agents access to session-spanning context, shared team memory, and knowledge enrichment, all stored and processed locally with no cloud dependency. Memento's suite of 20+ tools enables storing, recalling, searching, evolving, and managing structured memory, along with project management features such as decision tracking and collaborative context for teams.
