Subscribe to a MCP Server

You have to subscribe to a published MCP Server before using its tools in your applications. The subscription process fulfills the authentication process and provides you with access tokens that you can use to invoke a MCP Server's tools.

The examples here use the Petstore MCP Server, which is created and published to the Developer Portal in WSO2 API Manager.
