# Integrations

> Connect a Vapi assistant to external services using prebuilt integrations or service guides for API Request, Model Context Protocol (MCP), and Function tools.

Vapi can connect an assistant to an external service through a prebuilt integration or a standard tool such as [API Request](/tools/api-request), [Model Context Protocol (MCP)](/tools/mcp), or [Function](/tools/custom-tools).
