- updated the sdk version in all examples - fixed `kotlin-mcp-server` example (#331) ## Motivation and Context Removed the WASM example, as it duplicates the JVM example and only adds unnecessary complexity ## How Has This Been Tested? Locally ## Breaking Changes No ## Types of changes - [x] Bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update ## Checklist - [x] I have read the [MCP Documentation](https://modelcontextprotocol.io) - [x] My code follows the repository's style guidelines - [x] New and existing tests pass locally - [ ] I have added appropriate error handling - [x] I have added or updated documentation as needed

# MCP Kotlin Server Sample
|
|
|
|
A sample implementation of an MCP (Model Context Protocol) server in Kotlin that demonstrates different server
|
|
configurations and transport methods.
|
|
|
|
## Features
|
|
|
|
- Multiple server operation modes:
|
|
- Standard I/O server
|
|
- SSE (Server-Sent Events) server with plain configuration
|
|
- SSE server using Ktor plugin
|
|
- Built-in capabilities for:
|
|
- Prompts management
|
|
- Resources handling
|
|
- Tools integration
|
|
|
|
## Getting Started
|
|
|
|
### Running the Server
|
|
|
|
The server defaults to SSE mode with Ktor plugin on port 3001. You can customize the behavior using command-line arguments.
|
|
|
|
#### Default (SSE with Ktor plugin):
|
|
|
|
```bash
|
|
./gradlew run
|
|
```
|
|
|
|
#### Standard I/O mode:
|
|
|
|
```bash
|
|
./gradlew run --args="--stdio"
|
|
```
|
|
|
|
#### SSE with plain configuration:
|
|
|
|
```bash
|
|
./gradlew run --args="--sse-server 3001"
|
|
```
|
|
|
|
#### SSE with Ktor plugin (custom port):
|
|
|
|
```bash
|
|
./gradlew run --args="--sse-server-ktor 3002"
|
|
```
|
|
|
|
### Connecting to the Server
|
|
|
|
For SSE servers:
|
|
1. Start the server
|
|
2. Use the [MCP inspector](https://modelcontextprotocol.io/docs/tools/inspector) to connect to `http://localhost:<port>/sse`
|
|
|
|
For STDIO servers:
|
|
- Connect using an MCP client that supports STDIO transport
|
|
|
|
## Server Capabilities
|
|
|
|
- **Prompts**: Supports prompt management with list change notifications
|
|
- **Resources**: Includes subscription support and list change notifications
|
|
- **Tools**: Supports tool management with list change notifications
|
|
|
|
## Implementation Details
|
|
|
|
The server is implemented using:
|
|
- Ktor for HTTP server functionality (SSE modes)
|
|
- Kotlin coroutines for asynchronous operations
|
|
- SSE for real-time communication in web contexts
|
|
- Standard I/O for command-line interface and process-based communication
|
|
|
|
## Example Capabilities
|
|
|
|
The sample server demonstrates:
|
|
- **Prompt**: "Kotlin Developer" - helps develop small Kotlin applications with a configurable project name
|
|
- **Tool**: "kotlin-sdk-tool" - a simple test tool that returns a greeting
|
|
- **Resource**: "Web Search" - a placeholder resource demonstrating resource handling
