Send That Email
This wraps StupidAPIs' email analysis endpoint behind a single MCP tool that evaluates whether you should actually send that email you just drafted. It checks for passive aggression, calculates regret probability, and gives you a recommendation that's intentionally biased toward "don't send it." You'll need an X-API-Key from StupidAPIs to use it. It's part of the Pipeworx gateway, so you can either connect to this specific server or plug into the full Pipeworx hub for access to their entire catalog of 250+ data sources. The ask_pipeworx interface lets you query in plain English instead of calling tools directly. Useful as a sanity check before firing off something you might regret.
