What io.github.Alepha188838884/context-firewall does

Turn 50+ MCP tools into 4, and shrink large tool outputs by 60–95% (real HTML/JSON, measured — see benchmark) — for any MCP client, any model. Any output still over your configured token budget after compression is hard-truncated to that budget, with the full original retrievable via read_more.
