# 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 `auth` option.

## Usage example

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

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

## Constructor parameters

**publishableKey?:** (`string`): Your Clerk publishable key. Can be found in your Clerk Dashboard under API Keys. (Default: `process.env.CLERK_PUBLISHABLE_KEY`)

**secretKey?:** (`string`): Your Clerk secret key. Used for server-side authentication and token verification. (Default: `process.env.CLERK_SECRET_KEY`)

**jwksUri?:** (`string`): The JWKS URI from your Clerk application. Used to verify JWT signatures. (Default: `process.env.CLERK_JWKS_URI`)

**name?:** (`string`): Custom name for the auth provider instance.

**authorizeUser?:** (`(user: User, request: HonoRequest) => Promise<boolean> | boolean`): Custom authorization function to determine if a user should be granted access. Called after token verification. By default, allows all authenticated users.
