Summary
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.

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"send-that-email": {
"url": "https://gateway.pipeworx.io/send-that-email/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 673+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}

Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Send That Email data" })
The gateway picks the right tool and fills the arguments automatically.
