# stytchProvider

> Wire OAuth from Stytch Connected Apps

`stytchProvider` wires authentication through [Stytch Connected Apps](https://stytch.com/), so your tools receive a signed-in Stytch user.

## Example

```ts server.ts highlight={1,7-10} theme={null}
import { McpServer, stytchProvider } from "skybridge/server";

const server = new McpServer(
  { name: "personal-shopper", version: "0.0.1" },
  { capabilities: {} },
  {
    oauth: await stytchProvider({
      domain: process.env.STYTCH_DOMAIN,
      audience: process.env.STYTCH_PROJECT_ID,
    }),
  },
);
```

## Signature

```ts theme={null}
stytchProvider(opts: StytchProviderOptions): Promise<OAuthConfig>;
```

## Parameters

### `opts`

* **`domain`** is the project domain, for example `acme.customers.stytch.dev`, or a configured custom domain.

* **`audience`** is the Stytch Project ID, the audience Stytch binds into the token's `aud` claim.

It also accepts the shared [`CustomProviderOptions`](/api-reference/custom-provider#parameters) options: `baseUrl`, `serverUrl`, `scopes`, `requiredScopes`, and `metadataOverrides`.

Requires Dynamic Client Registration enabled in the Stytch dashboard.

## Returns

A `Promise` for the [`OAuthConfig`](/api-reference/custom-provider#returns) you pass to the [`oauth`](/api-reference/mcp-server#constructor) constructor option.
