# compaction-mcp

> Use this tool when you need to efficiently manage context and session data in MCP hosts, solving problems like context pressure and data persistence across sessions. It takes in MCP host data and outputs compacted context, summarized history, and re-hydrated files. This enables agents to gauge context pressure and make informed decisions, making it ideal for use cases requiring data-intensive and session-bound applications.
