Hookline runs on your own machine — the client starts it, so there is no endpoint to ping. 75 installs a week from npm. Last commit 20 Aug 2026.
Hookline MCP — create webhook endpoints, inspect requests, and validate payloads from AI agents.
Nothing serious here today
Today is the operative word: we check Hookline every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
