PromptFax

This connects Claude or ChatGPT to PromptFax's fax delivery service, letting you send actual faxes without leaving your chat session. You'd reach for this when you need to file something with a government office, send documents to a medical provider, or hit any other institution that still requires faxed submissions. It's pay per use at $2 to $4.50 per delivered fax, so you're not paying for a subscription to handle occasional fax requirements. The server exposes fax sending operations through a streamable HTTP transport, handling the conversion and delivery while you stay in your workflow.
