The Cline Memory Bank is a Model Context Protocol (MCP) server designed to provide persistent project context management for AI-assisted development, specifically tailored for use with the Cline VSCode extension. It acts as a 'memory' for your AI assistant, ensuring it retains knowledge of your project's details, ongoing tasks, and technical decisions across different coding sessions. This allows for more consistent, contextual AI assistance, reduces the need for repetitive explanations, and enhances overall development productivity by maintaining a log of project history and rationale.
