Claude Memory Manager MCP Server

Cross-session memory for Claude Code - never lose context between sessions. Claude Memory Manager automatically captures architectural decisions, code changes, bug fixes, and configuration choices from your Claude Code sessions, then intelligently retrieves relevant context when you start new sessions. It runs locally over stdio via the published package.

People who work with context, developer tools and memory and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
