Context Window Manager (CWM) acts as an MCP server designed to resolve the significant challenge of context exhaustion in large language model applications. Unlike traditional methods like summarization or Retrieval Augmented Generation (RAG) that incur information loss, CWM achieves true, lossless context restoration. It allows users to freeze an LLM's current KV cache to persistent storage, thaw it back later with perfect recall, or even clone contexts to explore alternative conversational paths. This is accomplished by leveraging vLLM's prefix caching and LMCache for tiered KV cache storage across GPU, CPU, disk, and Redis, ensuring seamless integration via the Model Context Protocol (MCP).
