What your AI can do with Oh Fax
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “quote_fax”: Price a fax before committing to anything. Validates the destination and the document, counts pages, and returns an exact total plus a payme.”
“Use “send_fax”: Returns the authorization instructions for sending a previously quoted fax. THIS ACTION COSTS MONEY AND CANNOT BE UNDONE: paying the returne.”
“Use “get_fax_status”: Current delivery state of a fax: awaiting_payment, paid, submitted, sending, delivered, or failed. Failed faxes include a reason you can act.”
“Use “get_fax_receipt”: Verifiable delivery receipt for a completed fax. Available once the fax has reached a final state. Use this to prove the workflow finished.”
How secure is the Oh Fax MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Oh Fax holds up.
Official endpoint
Operated by Oh Fax (ohfax.com) 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 Oh Fax adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

https://app.ohfax.com/mcpQuestions, answered
