Why we included this project

The official Kotlin SDK for Model Context Protocol gives Kotlin developers a way to implement both MCP clients and servers without writing the wire protocol themselves. Because it is Kotlin Multiplatform, the same code compiles to JVM, Native, JS, and Wasm, and the coroutine-based APIs fit naturally into idiomatic Kotlin projects. It covers the main transports, including stdio, SSE, streamable HTTP, and WebSocket, so you can connect a local CLI tool or a networked service. JetBrains helps maintain it, which is a good sign for teams already invested in the Kotlin ecosystem. This is a developer library, so its value shows up when you integrate MCP into an existing JVM or multiplatform application rather than as a standalone tool.
