Agents built with TanStack AI can now call OAuth-protected MCP servers through Vercel Connect, with no credentials for you to store or rotate.

The new `@vercel/connect/tanstack-ai` subpath exports `connectMCPTransport`, which takes a TanStack transport config and attaches a Connect-backed auth provider. The provider is called before every MCP request, so the token is always fresh.

If the user has not granted access, `createMCPClient` fails with a consent challenge before the model runs. Catch it with `getConsentChallenge` and redirect to Connect's consent URL. Otherwise, a consent error raised within a tool call would reach the model as an error string rather than the user as a redirect.
