osiris-mcp

A standard MCP server that acts as a cache-aware context engine and state governor for AI agents. It provides server-side payload filtering, lossless pruning, and prefix integrity to manage context windows efficiently. The server includes tools for observing dropped payloads, recalling filtered content, planning context pressure, and performing reversible session compaction.
