MastraAuthClerk Class

The MastraAuthClerk class provides authentication for Mastra applications using Clerk. It verifies incoming requests with Clerk-issued JWT tokens and integrates with the Mastra server using the experimental_auth option.

Usage example

import { Mastra } from "@mastra/core/mastra";
import { MastraAuthClerk } from "@mastra/auth-clerk";

export const mastra = new Mastra({
  // ..
  server: {
    experimental_auth: new MastraAuthClerk({
      jwksUri: process.env.CLERK_JWKS_URI,
      publishableKey: process.env.CLERK_PUBLISHABLE_KEY,
      secretKey: process.env.CLERK_SECRET_KEY,
    }),
  },
});
