Control What Your AI Can Do
You decide what AI agents can do with each connected account:
- Turn individual actions on or off for every connected account, so agents only see the actions you allow.
- Connect as Read-only or Read & Write. A read-only connection can only enable read actions.
- Destructive actions stay off by default. Actions such as deletes are disabled until an admin enables them.
- Team access per account. Restricted team members only use the accounts they are granted, with the read actions enabled on them.
Usage Examples
"Summarize the last day of messages in #marketing"
"Post the weekly report to #general"
"Remind me tomorrow at 9am to review campaigns"
