Connect Claude & ChatGPT to Sendmode

Ask your AI to text a customer, schedule a reminder to a whole group or check how much SMS credit is left. Through PipMCP your AI can send and schedule single and bulk SMS in Sendmode, cancel scheduled messages, find and add contacts, and look up or add opt-outs.

Connect Sendmode free

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

Try asking

“How much SMS credit do we have left?”
The AI reads the account's remaining credit balance.
“Text +353 87 123 4567 that the order is ready for pickup, from our sender ID.”
It sends the SMS right away with your message and sender ID. It uses credit and cannot be recalled.
“Schedule a reminder to these 40 numbers for Friday at 8:00.”
It schedules one bulk SMS for that time and returns a request ID you can use to cancel it.

What your AI can do

Send and schedule

Send an SMS to one number or a list right away, or schedule it for later.

Credit and cancelling

Check your credit balance and cancel a scheduled message or batch before it goes out.

Contacts and opt-outs

Find contacts by number, name, group or custom fields, add them to groups, and list or add opt-outs.

“Cancel the reminder I scheduled earlier.”
It cancels the scheduled message or batch by its request ID.
“Add Sean Murphy, +353 86 555 0101, to the Newsletter group.”
It adds the number with first and last name to the contact group, creating the group if needed.
“Has +353 85 222 3344 opted out?”
It checks the opt-out list for that number.

Questions

What can the AI do in Sendmode?

It can check your credit balance, send single and bulk SMS, schedule single and bulk SMS, cancel scheduled messages, find and add contacts, list opt-outs and opt a number out.

Does the AI see my Sendmode credentials?

No. Your Sendmode API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with the balance and contacts only. Sending SMS uses credit and cannot be recalled, so sending and scheduling can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then 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 with no credit card required. Paid plans bill per completed task. You connect your own Sendmode account, so the SMS credit you use is between you and Sendmode.

Why does my new Sendmode key not work yet?

New Sendmode API keys become active within 15 minutes, so wait a little and try again. If you turned on an IP check for the key, it must also allow PipMCP's server.
