Why use Vercel Connect with PreReason?

  • Credentials on demand

    Request PreReason credentials only when your application or agent needs them instead of copying secrets into application code.

  • Access for the right subject

    Support both user-authorized and app-scoped PreReason access from the same connection layer.

  • Centralized credential management

    Manage PreReason credentials in one place and retrieve them through a consistent runtime API.

  • Vercel-native controls

    Bind connections to the projects and environments that need them while Vercel OIDC authenticates each runtime request.

Use PreReason with your stack

Follow a complete setup for the Connect SDK or a supported agent framework.

Add PreReason to an existing Vercel application with the Connect SDK.

  1. Install the Connect SDK

  2. Create the PreReason connector

    vercel link
    vercel connect create prereason --name acme-prereason
    vercel env pull
