Kotlin Multiplatform implementation of the [Model Context Protocol](https://modelcontextprotocol.io) (MCP),
providing both client and server capabilities for integrating with LLM surfaces across various platforms.
## Overview
The Model Context Protocol allows applications to provide context for LLMs in a standardized way, separating the concerns of providing context from the actual LLM interaction. This Kotlin SDK implements the full MCP specification, making it easy to:
The Model Context Protocol allows applications to provide context for LLMs in a standardized way,
separating the concerns of providing context from the actual LLM interaction.
This SDK implements the MCP specification for Kotlin,
enabling you to build applications that can communicate using MCP on the JVM, WebAssembly and iOS.
- Build MCP clients that can connect to any MCP server
- Create MCP servers that expose resources, prompts and tools

## Samples
- [kotlin-mcp-server](./samples/kotlin-mcp-server): shows how to set up a Kotlin MCP server with different tools and other features.
- [kotlin-mcp-server](./samples/kotlin-mcp-server): demonstrates a multiplatform (JVM, Wasm) MCP server setup with various features and transports.
- [weather-stdio-server](./samples/weather-stdio-server): shows how to build a Kotlin MCP server providing weather forecast and alerts using STDIO transport.
- [kotlin-mcp-client](./samples/kotlin-mcp-client): demonstrates building an interactive Kotlin MCP client that connects to an MCP server via STDIO and integrates with Anthropic’s API.

# MCP Kotlin Server Sample
A sample implementation of an MCP (Model Communication Protocol) server in Kotlin that demonstrates different server configurations and transport methods.
A sample implementation of an MCP (Model Communication Protocol) server in Kotlin that demonstrates different server
configurations and transport methods for both JVM and WASM targets.
## Features
- Multiple server operation modes:
- Standard I/O server
- SSE (Server-Sent Events) server with plain configuration
- SSE server using Ktor plugin
- Standard I/O server (JVM only)
- SSE (Server-Sent Events) server with plain configuration (JVM, WASM)
- SSE server using Ktor plugin (JVM, WASM)
- Multiplatform support
- Built-in capabilities for:
- Prompts management
- Resources handling

### Running the Server
To run the server in SSE mode on the port 3001, run:
You can run the server on the JVM or using Kotlin/WASM on Node.js.
#### JVM:
To run the server on the JVM (defaults to SSE mode with Ktor plugin on port 3001):
```bash
./gradlew run
./gradlew runJvm
```
#### WASM:
To run the server using Kotlin/WASM on Node.js (defaults to SSE mode with Ktor plugin on port 3001):
```bash
./gradlew wasmJsNodeDevelopmentRun
```
### Connecting to the Server
For SSE servers (both plain and Ktor plugin versions):
For servers on JVM or WASM:
1. Start the server
2. Use the MCP inspector to connect to `http://localhost:<port>/sse`
2. Use the [MCP inspector](https://modelcontextprotocol.io/docs/tools/inspector) to connect to `http://localhost:<port>/sse`
## Server Capabilities
@ -42,3 +57,4 @@ The server is implemented using:
- Kotlin coroutines for asynchronous operations
- SSE for real-time communication
- Standard I/O for command-line interface
- Common Kotlin code shared between JVM and WASM targets
