MCP Kotlin SDK Tutorial: Building Multiplatform MCP Clients and Servers

Learn how to implement MCP client/server workflows with modelcontextprotocol/kotlin-sdk, including module boundaries, transport choices, capability negotiation, and production lifecycle controls.

Why This Track Matters

Kotlin teams increasingly need one MCP implementation that works across JVM, Native, JS, and Wasm. The official Kotlin SDK offers a clean split across core, client, and server modules with coroutine-friendly APIs and transport adapters for local and remote workflows.

This track focuses on:

• selecting the right module/artifact strategy for your codebase
• building capability-safe clients and servers with typed APIs
• choosing stdio, SSE, streamable HTTP, or WebSocket transports by workload
• running conformance, release, and upgrade workflows with low drift

03 - Client Runtime and Capability Negotiation	How do Kotlin clients connect safely and use server features?	Safer client behavior
04 - Server Runtime, Primitives, and Feature Registration	How do I expose tools/resources/prompts with capability discipline?	Stronger server design
05 - Transports: stdio, Streamable HTTP, SSE, and WebSocket	Which transport should I run in each environment?	Better transport decisions
06 - Advanced Client Features: Roots, Sampling, and Elicitation	How do advanced MCP features change client behavior?	Better UX and control
07 - Testing, Conformance, and Operational Diagnostics	How do I validate SDK behavior and catch drift early?	Higher reliability
