Class McpClientRegistration

java.lang.Object

com.tnsai.mcp.auth.McpClientRegistration

public class McpClientRegistration
extends Object

RFC 7591 Dynamic Client Registration for MCP OAuth.

Enables MCP clients to dynamically register with an OAuth authorization server without manual client registration. This is useful for public MCP clients that need to authenticate with servers discovered at runtime.

Usage:

 RegistrationRequest request = new RegistrationRequest(
     "TnsAI MCP Client",
     List.of("http://localhost:8080/callback"),
     List.of("authorization_code"),
     List.of("code"),
     "none"
 );

 RegistrationResponse response = McpClientRegistration.register(
     "https://auth.example.com/register",
     request
 );

 String clientId = response.clientId();
