MCP Swift SDK Tutorial: Building MCP Clients and Servers in Swift

Learn how to implement MCP client and server workflows with modelcontextprotocol/swift-sdk, including transport options, sampling, batching, and graceful service lifecycle control.

Why This Track Matters

Swift teams building local-first AI tooling and Apple-platform workflows need clear MCP integration guidance. The official Swift SDK provides both client and server surfaces with practical transport and lifecycle controls.

This track focuses on:

• choosing transport and capability strategies for Swift clients
• implementing server tools/resources/prompts with safer lifecycle handling
• using sampling and batching patterns without losing user control
• managing strict-mode behavior, debugging, and release drift

Current Snapshot (auto-updated)
