# AI & MCP

LLM-powered steps inside your flows, the guardrails that check what passes through them, and the MCP servers that expose a chosen slice of your Tools and APIs to external AI clients.

The end users who sign in to your MCP servers, and their groups and roles, are managed under [Account & admin](/api/api-reference/account-and-admin.md).
