Delegate AuthorizationRedirectDelegate

Namespace

ModelContextProtocol.Authentication

Assembly

ModelContextProtocol.Core.dll

Represents a method that handles the OAuth authorization URL and returns the authorization code.

public delegate Task<string?> AuthorizationRedirectDelegate(Uri authorizationUri, Uri redirectUri, CancellationToken cancellationToken)

Parameters

authorizationUri Uri

The authorization URL that the user needs to visit.

redirectUri Uri

The redirect URI where the authorization code will be sent.

cancellationToken CancellationToken

The cancellation token.

Returns

Task<string>

A task that represents the asynchronous operation. The task result contains the authorization code if successful, or null if the operation failed or was cancelled.

Remarks

This delegate provides SDK consumers with full control over how the OAuth authorization flow is handled. Implementers can choose to:

• Start a local HTTP server and open a browser (default behavior)
• Display the authorization URL to the user for manual handling
• Integrate with a custom UI or authentication flow
• Use a different redirect mechanism altogether

The implementation should handle user interaction to visit the authorization URL and extract the authorization code from the callback. The authorization code is typically provided as a query parameter in the redirect URI callback.
