Connect Claude & ChatGPT to Sendon

Ask your AI to send an SMS, LMS or MMS from one of your registered sender numbers, or a Kakao AlimTalk message from an approved template. It can check how a send went, cancel a scheduled send, write AlimTalk templates and submit them for review, and keep an eye on your points and the opt-out list.

Connect Sendon free

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

Try asking

“Text 010-1234-5678 that the order is ready for pickup, from our main sender number.”
The AI lists your registered sender numbers, picks the one you mean and sends the SMS. It is a real message and uses points.
“How did yesterday's appointment reminder go? Did any messages fail?”
It finds the send request and lists each message with its delivery status, so you can see which numbers failed.
“Cancel the SMS we scheduled for tomorrow morning.”
It finds the scheduled send request and cancels it before it goes out. A cancel cannot be undone.

What your AI can do

SMS, LMS and MMS

Send text messages from registered sender numbers, schedule them, send a scheduled batch now or cancel it, and read delivery results per message.

Kakao AlimTalk

List your Kakao channels, create and update AlimTalk templates, submit them for review and send AlimTalk messages with an optional SMS fallback.

Points and opt-outs

Check your point balance, message prices and payment history, and add or remove numbers on the opt-out blocklist.

“Write an AlimTalk template for shipping notices and send it for review.”
It creates the template on your Kakao channel and submits it to Kakao for review. It can be used once it is approved.
“How many points do we have left, and what does an LMS cost?”
It reads your point balance and history and lists the price per message type.
“Stop sending messages to 010-9876-5432.”
It adds the number to your opt-out blocklist, so it no longer receives messages.

Set up in three steps

1
Pick the app
Create a free PipMCP account and choose Sendon from the app list.
2
Paste your key
Enter your Sendon account ID as the username and a Sendon API key as the password. You need a verified business account. In the Sendon console open 마이페이지 > API KEY and click 새로운 API KEY 생성, then copy the key. Sending through the API also requires the calling server's IP on the key's allow-list (API KEY 관리 > 허용 IP 관리), so add PipMCP's server IP there.
3
Add the link to your AI
You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:
1. Click your name, then Settings › Connectors › Add custom connector.
2. Paste your link as the Remote MCP server URL.
3. Switch it on from the + menu in a chat.

Questions

What can the AI do in Sendon?

The AI can send SMS, LMS and MMS messages, read send requests and their delivery results, send a scheduled batch right away or cancel it. It can list your Kakao channels, create, update and submit AlimTalk templates for review, and send AlimTalk messages. It can also read your points, prices and payments and manage the opt-out blocklist.

Does the AI see my Sendon credentials?

No. Your Sendon account ID and API key are encrypted at rest and never shown to the AI. After you save them, they are 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 only delivery results and point balance. Sending an SMS or AlimTalk message reaches real people and uses points, and cancelling a scheduled send cannot be undone. These actions 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 also need your own Sendon account.

Why do I need to add an IP address in Sendon?

Sendon only accepts API sends from IP addresses on the key's allow-list. Because PipMCP makes the calls to Sendon for you, add PipMCP's server IP under API KEY 관리 > 허용 IP 관리 in the Sendon console. Otherwise sending messages through the API is refused.
