Kotlin MCP SDK Samples

Runnable projects demonstrating MCP server and client implementations with the Kotlin MCP SDK. For background on the protocol itself, see the MCP documentation.

Overview

Sample Type Transport MCP Features
simple-streamable-server Server Streamable HTTP Tools, Resources, Prompts, Logging
kotlin-mcp-server Server STDIO, SSE Tools, Resources, Prompts
weather-stdio-server Server STDIO Tools
kotlin-mcp-client Client STDIO Tool discovery & invocation
notebooks Client (Notebook) Streamable HTTP Tool discovery & invocation

Getting Started

  • Building a server? Start with simple-streamable-server — it uses the recommended Streamable HTTP transport and covers tools, resources, prompts, and logging.
  • Building a client? Open the notebooks sample for a step-by-step walkthrough, or see kotlin-mcp-client for a full CLI client with Anthropic API integration.

Samples

Simple Streamable HTTP Server

A minimal Streamable HTTP server with optional Bearer token authentication. Demonstrates tools (greet, multi-greet), a prompt template, a resource, and server-to-client logging notifications. Read more →

Kotlin MCP Server

A multi-transport server supporting STDIO, SSE (plain), and SSE (Ktor plugin). Useful for exploring different transport modes side by side. Read more →

Weather STDIO Server

A focused STDIO server that exposes weather forecast and alert tools backed by the weather.gov API. Includes Claude Desktop integration instructions. Read more →

Kotlin MCP Client

An interactive CLI client that connects to any MCP server over STDIO and routes queries through Anthropic's Claude API, bridging MCP tools with LLM conversations. Read more →

MCP Client Notebook

A Kotlin notebook that connects to a remote MCP server via Streamable HTTP and demonstrates ping, tool listing, and tool invocation — all in an interactive cell-by-cell format. Read more →
