SMS Alert for AI agents

SMS Alert is a multi-channel messaging platform that sends SMS, RCS, Telegram, and WhatsApp messages through one API, used for marketing and transactional alerts. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

01 · USE CASES

What agents do in SMS Alert.

01

Send an SMS to a customer

Send an SMS through a chosen sender ID, using a template already approved for that type of message.

02

Check delivery before resending

Check the delivery report for a sent message before deciding whether to resend it through another channel.

03

Confirm before deleting a contact

Look up a contact's group and history before deleting it, since the removal takes it out of every list.

02 · ACTIONS

23 SMS Alert actions, graded by risk.

Every SMS Alert action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

  2. 02You set the rulesReads run, writes like “send SMS via XML” can wait for the user, and “delete Group” can be denied outright.
  3. 03Any agent can actYour agent calls SMS Alert through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('sms_alert', {
  read: 'allow',
  write: 'ask',        // send_sms_xml
  destructive: 'deny',  // post_delete_group

04 · AUTH AND DATA

How SMS Alert connects.

Users add their SMS Alert api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same SMS Alert connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

SMS Alert and Arc0, answered.

Q01

Can I use SMS Alert with Claude, ChatGPT or Cursor?

Yes. Connect SMS Alert to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the SMS Alert actions you allow.

Q02

How do users connect SMS Alert?

Users add their SMS Alert api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which SMS Alert actions can my agent take?

23 in total: 7 read, 12 write and 4 destructive, such as “send SMS via XML”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in SMS Alert?

Yes. Actions like “delete Group” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call SMS Alert too?

Yes. The same SMS Alert connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
