XCREENER runs on your own machine — the client starts it, so there is no endpoint to ping. 43 installs a week from npm. Last commit 14 Aug 2026.
Local stdio MCP bridge for XCREENER's XQL screener API — validate, explain, and run queries.
Today is the operative word: we check XCREENER every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
