Connect Claude & ChatGPT to Twilio

Ask your AI to send an SMS or find out why a call failed, and it does it in your Twilio account. It can look up messages, calls, recordings and transcriptions, list your phone numbers and check usage and balance. It can also place outbound calls and cancel scheduled messages.

Connect Twilio free

Free plan, no credit card. Takes about a minute.

Try asking

“Was message SM8a1f... delivered, and if not, why?”
The AI reads the message's status, price and error code.
“Text +45 20 12 34 56 from our support number: 'Your order is ready for pickup.'”
It finds your number and sends the SMS. It is delivered right away and carrier fees apply.
“How much did we spend on SMS last month?”
It lists usage records for the SMS category in that date range, with cost.

What your AI can do

Messages and calls

Send SMS or MMS, place outbound calls with TwiML or a URL, and hang up or redirect a call in progress.

Logs and troubleshooting

Look up messages, calls, recordings and transcriptions by SID, and read call events to see why a call failed.

Numbers, usage and balance

List your phone numbers and verified caller IDs, check usage and cost by category and see your prepaid balance.

“Read me the latest voicemail transcription.”
It lists transcriptions newest first and fetches the text of the most recent one.
“Why did call CA41c2... fail?”
It reads the call's details and the request and response events Twilio logged for it.
“Cancel the scheduled reminder SM77b0...”
It sets the scheduled message to canceled so it is never sent.

Questions

What can the AI do in Twilio?

It can send SMS and MMS, place outbound calls, and hang up or redirect calls in progress. It can cancel scheduled messages, redact a sent message's body and delete message records. It can also read messages, calls, call events, recordings, transcriptions, phone numbers, verified caller IDs, usage and your balance.

Does the AI see my Twilio API key?

No. You paste your Twilio Account SID and Auth Token into PipMCP once. It is encrypted at rest, never shown to the AI and never shown again after you save it. The AI only gets 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, for example lookups and usage only. Risky actions, like sending an SMS or deleting a message record, 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) and in Cursor.

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 Twilio account, so anything Twilio charges is between you and Twilio.

Do SMS and calls sent by the AI cost money?

Yes. Messages and calls go through your own Twilio account and are billed there, and carrier fees apply to SMS. A sent SMS cannot be recalled, and a call starts right away. If you want to confirm each one, require approval for send_sms and make_call.
