Memory Bank MCP is a Model Context Protocol (MCP) server designed to manage Memory Banks, which are structured repositories of project and system information. It allows AI assistants to initialize, read, write, and update Memory Bank files, such as project context, active tasks, progress, and decisions. It supports different operational modes like code, architect, ask, debug, and test, to tailor the AI's behavior. The system ensures persistent context maintenance, decision logging, and progress tracking, making it an essential tool for continuous project management and AI-assisted development across sessions. Its robust error handling, status prefix system, and customizability enhance user experience and operational transparency.
