Features

• MCP protocol-compliant server
• Presentation of crypto-related information
• Presentation economic events, stock overview, income statement, cash flow and etc. about financial-related information
• Communication via Stdio
• Easy expandability

Installation

Add the new repository to your build file:

repositories {
    mavenCentral()
}

Quick Start

Creating a Client

import io.modelcontextprotocol.kotlin.sdk.client.Client
import io.modelcontextprotocol.kotlin.sdk.client.StdioClientTransport
import io.modelcontextprotocol.kotlin.sdk.Implementation

val client = Client(
    clientInfo = Implementation(
        name = "example-client",
        version = "1.0.0"
    )
)

val transport = StdioClientTransport(
    inputStream = processInputStream,
    outputStream = processOutputStream
)

// Connect to server
client.connect(transport)

// List available resources
val resources = client.listResources()

// Read a specific resource
val resourceContent = client.readResource(
    ReadResourceRequest(uri = "file:///example.txt")
)

Creating a Server

import io.modelcontextprotocol.kotlin.sdk.server.Server
import io.modelcontextprotocol.kotlin.sdk.server.ServerOptions
import io.modelcontextprotocol.kotlin.sdk.server.StdioServerTransport
import io.modelcontextprotocol.kotlin.sdk.ServerCapabilities

val server = Server(
    serverInfo = Implementation(
        name = "example-server",
        version = "1.0.0"
    ),
    options = ServerOptions(
        capabilities = ServerCapabilities(
            resources = ServerCapabilities.Resources(
                subscribe = true,
                listChanged = true
            )
        )
    )
)

// Add a resource
server.addTool(
        name = "example-tool",
        description = "Example Description",
        inputSchema = Tool.Input(
            properties = buildJsonObject { },
            required = emptyList()
        )
    ) { _ ->
        val newsList = runBlocking { httpClient.getExample(apiKey) }
        CallToolResult(
            content = exampleList.map {
                TextContent("""
                    Title: ${it.title}
                    Description: ${it.description}
                    URL: ${it.url}
                    Thumbnail: ${it.thumbnail}
                    Created At: ${it.createdAt}
                """.trimIndent())
            }
        )
    }

// Start server with stdio transport
val transport = StdioServerTransport()
server.connect(transport)
