Send That Email

pipeworx-io/mcp-send-that-email
HTTPregistry active
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.

mcp-send-that-email

send-that-email MCP — wraps StupidAPIs (requires X-API-Key)

Part of Pipeworx — an MCP gateway connecting AI agents to 673+ live data sources.

Tools

ToolDescription
send_that_email_analyzeAnalyze whether you should send that email. Evaluates passive aggression, regret probability, and provides a recommendation (heavily weighted toward no).

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.
