Is SendFaxFast MCP safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_fax_status unknown never probed

  Check the delivery status of a fax. Use token for pay-per-fax orders, fax_id for subscription orders (fax_id requires your API key; only your own faxes are visible).

• send_fax unknown never probed

  Send a PDF document to a fax number. WITHOUT API key: returns a Stripe checkout link (pay-per-fax from $2.49) – the fax is sent after the user pays. WITH a Mini/Flex subscription key (sff_...): sends immediately from the subscription quota. The document must be a direct, publicly accessible HTTPS link to a PDF (max. 10 MB). Supported: USA, Canada, Australia, New Zealand and 39 more countries (same list as sendfaxfast.com); premium-rate numbers are not supported. Each call transmits (or, for pay-per-fax, prepares the checkout for) a real fax to the given number. DOCUMENT (exactly one): "upload_id" from create_upload_link (for files on the user's device), "file" (a file attached in ChatGPT, filled in automatically), "document_url" (direct public HTTPS link to a PDF) or "document_base64" (tiny files only, max. 700 KB). For an attachment that is not available as "file", create_upload_link provides an upload link. The result states whether the fax was sent, scheduled or is awaiting payment.

• create_upload_link unknown never probed

  Creates a secure one-time upload link (valid 30 minutes) for the fax document (PDF, JPG or PNG, max. 10 MB) – upload from phone or computer by drag & drop, file picker or camera. For files on the user's device, or chat attachments that are not available as send_fax's "file" parameter. The user opens upload_url and uploads the file; send_fax then accepts the returned upload_id. Creating a link sends nothing and costs nothing.
