Provides memory storage between sessions for Claude Desktop application, solving the problem of context loss when reaching token limits or starting new chats. Automatically saves and restores project context, architectural decisions, communication preferences, and maintains complete isolation between different projects.

Notes

Specifically designed for Claude Desktop application users. Requires Python 3.8+. Uses the 'general' project scope by default if not explicitly specified. For proper project isolation, include the project identifier in Claude's custom instructions. Redis support is experimental with unvalidated performance characteristics. All data remains fully local and private with no external communication.
