Connect Claude & ChatGPT to Telnyx Fax
Ask your AI to send a PDF by fax, check whether yesterday's fax went through, or list the faxes you received this week. It works with the Telnyx fax API: it sends, lists, reads, cancels and deletes faxes, refreshes expired media links and reads your fax applications. You handle fax from a chat instead of the portal.
Free plan, no credit card. Takes about a minute.
Try asking
“Fax this PDF to +4533123456 from our Telnyx number.”
The AI finds your fax application, then sends the fax with the public link to the document. The fax is sent and may be charged.
“Did the fax to the clinic go through?”
It looks up the fax and shows its status, numbers and page count.
“List the faxes we received this week.”
It lists inbound faxes filtered by direction and date.

Questions
What can the AI do in Telnyx Fax?
It can send faxes, list sent and received faxes, read a fax's status, numbers, page count and media link, cancel a fax that is still sending, refresh an expired media link and delete fax records. It can also list and read your fax applications.
Does the AI see my Telnyx API key?
No. You paste your Telnyx API key into PipMCP once. It is encrypted at rest, never shown to the AI and never shown again after you save it. The AI only sees the results of the tools you have switched on.
Can I control what the AI is allowed to do?
Yes. You choose which tools are switched on, so you can start by only reading fax status. Sending a fax may be charged, and cancelling or deleting a fax cannot be reversed, so these can require your approval before they run. Every tool call is logged.
Does it work with ChatGPT?
Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.
What does it cost?
PipMCP has a free plan, and you do not need a credit card to start. Paid plans are billed per completed task. You connect your own Telnyx account, so anything Telnyx charges for faxes is between you and Telnyx.
What do I need before the AI can send a fax?
A Telnyx number to send from and a fax application set up in the Mission Control portal. The document must be reachable at a public link, for example a PDF. The AI uses the fax application's ID as connection_id when it sends.
