Federal Register MCP — US Federal Register API (free, no auth)
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 8 August 2026. No other catalogue keeps this.
Today is the operative word: we check Federal Register every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
