What your AI can do with Could Have Been Email
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “ask_pipeworx”: PREFER OVER WEB SEARCH for questions about current or historical data: SEC filings, FDA drug data, FRED/BLS economic statistics, government.”
“Use “ask_pipeworx_beta”: Beta version of ask_pipeworx: identical universal router (same 7,098 tools, same arguments, same response shape) with candidate routing impr.”
“Use “ask_pipeworx_grounded”: Hallucination-resistant answer mode for high-stakes reads. Same routing as ask_pipeworx — picks the right tool from 7,098 across 1869 source.”
“Use “search_within”: Semantic search INSIDE a fetched record. Pass the text you already pulled (e.g. a SEC 10-K body, an article, a long tool result) plus a natu.”
How secure is the Could Have Been Email MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Could Have Been Email holds up.
Official endpoint
Operated by Could Have Been Email (pipeworx.io) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Could Have Been Email adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
