Connectors and integrations
Over 3,000 tools Justin can work through. Connect them, and revoke them whenever you like.
Justin connects to over 3,000 tools — Google Sheets, HubSpot, Zendesk, Notion, Salesforce and the rest — plus any system of your own. It reaches one only after someone on your team authorizes it, and nothing is connected by default.
1. Connect a tool
Pick any of the 3,000+ apps in the catalog and authorize it the usual way.
By default, a tool one person connects is available to the whole team.
You can narrow that per connector — leave it open to everyone, or limit it to the people who should have it.
2. What Justin can do with it
It reads freely, within the scopes you approved.
Anything that writes — sending an email, editing a page — waits for your approval in the channel.
Each integration has an Accounts and a Tools view, so you can see exactly what Justin is able to call.
3. Add your own system
Use + Add custom MCP in app.getjustin.ai/connectors.
Your engineers set it up once, and the whole team can use it from Slack.
4. Disconnect
Revoke a connector in app.getjustin.ai/connectors, or from the third-party app itself.
New requests stop reaching it immediately.
You can also just ask Justin in chat to disconnect something.
