   Hello,

   Previously I'ved used the Python SDK to work with an MCP client to great success.

   However, I'm at a bit of a loss here. I see that there is a way to use the kotlin sdk in order to do MCP client interactions. But I cannot seem to figure out how to do so.

   I know you have these two files

   • https://github.com/modelcontextprotocol/kotlin-sdk/blob/main/kotlin-sdk-client/src/commonMain/kotlin/io/modelcontextprotocol/kotlin/sdk/client/StreamableHttpClientTransport.kt
   • https://github.com/modelcontextprotocol/kotlin-sdk/blob/main/kotlin-sdk-client/src/commonTest/kotlin/io/modelcontextprotocol/kotlin/sdk/client/StreamableHttpClientTransportTest.kt

   But I cannot for the life of me figure out what to do with this?

   At best my current effort looks like this

   package com.example.myapplication
   
   import android.os.Bundle
   import androidx.appcompat.app.AppCompatActivity
   import androidx.lifecycle.lifecycleScope
   
   //Third-Party?
   import io.ktor.client.HttpClient
   import io.ktor.client.engine.cio.CIO
   import io.modelcontextprotocol.kotlin.sdk.client.StreamableHttpClientTransport
   import kotlinx.coroutines.launch
   
   class MainActivity : AppCompatActivity() {
       override fun onCreate(savedInstanceState: Bundle?) {
           super.onCreate(savedInstanceState)
           setContentView(R.layout.activity_main)
   
           // -----------------------------------------------------------------------
           // MCP Client
           // -----------------------------------------------------------------------
           val client = HttpClient(CIO)
   
           val transport = StreamableHttpClientTransport(client,
                                                         "http://server_url/mcp");
   
           lifecycleScope.launch {
               transport.start()
               client.close()
           }
       }
   }

   But I'm not sure really how to work with this?

   How are we supposed to use the kotlin sdk to interact with an MCP Server?

   I'm more than happy to help with crafting an example for the community, but I'm not really an android developer. Any guidance would be greatly appreciated 😄
