Hi I am an AI enthusiast and exploring MCP right now. Having a background of mostly C# I am working on Semantic kernel and wondering if there's a way to register an OpenAPI plugin to MCP server. I understand MCPServer.Register is currently used for a native plugin, please correct me if I am wrong.

So currently the semantic kernel function registration logic only picks up kernel functions written with the attribute method - can you show me how you are declaring the openAI plugin? Chances are I can expand the register method to capture that format as well, or you may be able to extract an AIFunction (Microsoft.Extensions.AI) and register that.

It is the OpenAPI plugin as from the MS docs here https://learn.microsoft.com/en-us/semantic-kernel/concepts/plugins/adding-openapi-plugins?pivots=programming-language-csharp
So basically I have an Azure function app with some APIs and I got the OpenAPI spec for those APIs and created a plugin for it in Semantic Kernel.
Sample code:
KernelPlugin plugin = await OpenApiKernelPluginFactory.CreateFromOpenApiAsync(
pluginName: "lights",
filePath: "path/to/lights.json"
);
