What is MCP Kotlin Minimal Client Server Sample?
This is a minimal Kotlin client-server sample demonstrating the Model Context Protocol (MCP). It simulates a weather tool where a client application interacts with a server to retrieve weather information, orchestrated by an LLM.
How to use MCP Kotlin Minimal Client Server Sample?
The sample includes a client (Client.kt) and a server (server.main.kts). The diagrams show the initialization and tool execution flow. The client connects to the server, discovers available tools (e.g., 'get_weather'), and then uses an LLM to determine when and how to call those tools. The LLM then receives the tool's response and generates a final response to the user.

FAQ from MCP Kotlin Minimal Client Server Sample
What is MCP?
What is MCP?
MCP stands for Model Context Protocol, a protocol for client-server interaction, especially useful for connecting LLMs with external tools.
What is the purpose of this sample?
What is the purpose of this sample?
This sample demonstrates a minimal implementation of MCP using Kotlin, showcasing how a client can discover and execute tools on a server, guided by an LLM.
How does the LLM fit into the picture?
How does the LLM fit into the picture?
The LLM decides which tool to use based on the user's input and the available tool information provided by the server. It also generates the final response to the user based on the tool's output.
What is the 'get_weather' tool?
What is the 'get_weather' tool?
The 'get_weather' tool is a simulated tool on the server that returns the weather information for a given location.
Where can I find the client and server code?
Where can I find the client and server code?
The client code is located in src/main/kotlin/Client.kt, and the server code is in server.main.kts.
