What is the replacement for the deprecated MCP plugin?

As of v1.4.10, the MCP plugin is deprecated and has been replaced by the more powerful OAuth 2.1 Provider plugin for building custom authorization servers.

Does Better Auth support Cloudflare D1 directly?

No, Better Auth does not have a native d1Adapter. You must use either Drizzle ORM or Kysely as an intermediary adapter to connect to Cloudflare D1.

Can I use Better Auth with TanStack Start?

Yes, but it requires the reactStartCookies plugin to be placed last in your plugin array to ensure cookies are handled correctly by the framework's internal systems.

How do I initialize Better Auth in a serverless worker?

Because D1 database bindings are only available inside the request handler, you must use a factory pattern to initialize the Better Auth instance inside the fetch() function.

About

This skill provides specialized guidance for implementing Better Auth, a comprehensive self-hosted authentication framework designed for modern TypeScript environments. It helps developers navigate complex configurations such as the D1 adapter requirements (necessitating Drizzle or Kysely), stateless session management, and multi-tenant SaaS structures with RBAC. By leveraging this skill, developers can avoid common pitfalls like serverless initialization errors in Cloudflare Workers, ensuring robust implementations of passkeys, 2FA, and custom OAuth 2.1 providers while maintaining full control over their authentication data.
