How agents use integrations
Your agent uses integrations as tools within conversations:
- Customer asks "Where is my order?" → agent checks Shopify and responds with tracking
- Prospect wants to book a call → agent checks Google Calendar and offers available times
- Client needs a payment receipt → agent pulls it from Stripe and sends it
You control which integrations each agent can access, maintaining granular control over permissions.
MCP Support
Custom Agents also supports the Model Context Protocol (MCP) — an open standard for connecting AI agents to external tools. This makes integrations more reliable, standardized, and easier to extend.
