# Integrations **Integrations** are the first thing you should set up as these are needed to create any runs. Manage them at * **Managed** - We host auth & connector logic; click-to-connect. Just toggle the switch and it will work. * **Custom** - Bring your own OpenAPI spec or register a remote MCP. Define auth and scopes, and keep specs focused on allowed actions. * When creating runs, specify the integrations by passing `customerIntegrationIds` inside `selectedCustomerIntegrationIds`. * This deterministically controls which tools are available for the run. * Use `["*"]` to allow all active integrations (be cautious in production).
