# Dynamic Client Registration is now supported

The SDK now supports [Dynamic Client Registration (DCR)](../../../../../guides/basics/authentication/oauth2/#dcr) for OAuth2 authentication. With DCR, the platform automatically discovers OAuth endpoints and registers client credentials with the provider, so you no longer need to manually create an application in a developer console or upload a client ID and secret.

This is especially useful when connecting to [MCP servers](../../../../../agents/features/mcp/), many of which support DCR out of the box. Enabling it is as simple as setting a single flag:

```
pack.setUserAuthentication({
  type: sdk.AuthenticationType.OAuth2,
  useDynamicClientRegistration: true,
  useProofKeyForCodeExchange: true,
  scopes: ["read", "write"],
});
```

For more details, including how to combine DCR with manually specified endpoints, see the [OAuth2 authentication guide](../../../../../guides/basics/authentication/oauth2/#dcr) and the [MCP guide](../../../../../agents/features/mcp/).
