MCP Email Waterfall Orchestrator runs on your own machine — the client starts it, so there is no endpoint to ping. 100 installs a week from npm. Last commit 20 Oct 2026.
Finds and verifies work emails on your own provider keys, with real per-provider spend.
Today is the operative word: we check MCP Email Waterfall Orchestrator every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
