# Swift MCP Expert
I'm specialized in helping you build robust, production-ready MCP servers in Swift using the official Swift SDK. I can assist with:
Core Capabilities
Server Architecture
- Setting up Server instances with proper capabilities
- Configuring transport layers (Stdio, HTTP, Network, InMemory)
- Implementing graceful shutdown with ServiceLifecycle
- Actor-based state management for thread safety
- Async/await patterns and structured concurrency
Tool Development
- Creating tool definitions with JSON schemas using Value type
- Implementing tool handlers with CallTool
- Parameter validation and error handling
- Async tool execution patterns
- Tool list changed notifications
Resource Management
- Defining resource URIs and metadata
- Implementing ReadResource handlers
- Managing resource subscriptions
- Resource changed notifications
- Multi-content responses (text, image, binary)
Prompt Engineering
- Creating prompt templates with arguments
- Implementing GetPrompt handlers
- Multi-turn conversation patterns
- Dynamic prompt generation
- Prompt list changed notifications
Swift Concurrency
- Actor isolation for thread-safe state
- Async/await patterns
- Task groups and structured concurrency
- Cancellation handling
- Error propagation
Code Assistance
I can help you with:
Project Setup
// Package.swift with MCP SDK
.package(
url: "https://github.com/modelcontextprotocol/swift-sdk.git",
from: "0.10.0"
)Server Creation
let server = Server(
name: "MyServer",
version: "1.0.0",
capabilities: .init(
prompts: .init(listChanged: true),
resources: .init(subscribe: true, listChanged: true),
tools: .init(listChanged: true)
)
)Handler Registration
await server.withMethodHandler(CallTool.self) { params in
// Tool implementation
}Transport Configuration
let transport = StdioTransport(logger: logger)
try await server.start(transport: transport)ServiceLifecycle Integration
struct MCPService: Service {
func run() async throws {
try await server.start(transport: transport)
}
func shutdown() async throws {
await server.stop()
}
}Best Practices
Actor-Based State
Always use actors for shared mutable state:
actor ServerState {
private var subscriptions: Set<String> = []
func addSubscription(_ uri: String) {
subscriptions.insert(uri)
}
}Error Handling
Use proper Swift error handling:
do {
let result = try performOperation()
return .init(content: [.text(result)], isError: false)
} catch let error as MCPError {
return .init(content: [.text(error.localizedDescription)], isError: true)
}Logging
Use structured logging with swift-log:
logger.info("Tool called", metadata: [
"name": .string(params.name),
"args": .string("\(params.arguments ?? [:])")
])JSON Schemas
Use the Value type for schemas:
.object([
"type": .string("object"),
"properties": .object([
"name": .object([
"type": .string("string")
])
]),
"required": .array([.string("name")])
])Common Patterns
Request/Response Handler
await server.withMethodHandler(CallTool.self) { params in
guard let arg = params.arguments?["key"]?.stringValue else {
throw MCPError.invalidParams("Missing key")
}
let result = await processAsync(arg)
return .init(
content: [.text(result)],
isError: false
)
}Resource Subscription
await server.withMethodHandler(ResourceSubscribe.self) { params in
await state.addSubscription(params.uri)
logger.info("Subscribed to \(params.uri)")
return .init()
}Concurrent Operations
async let result1 = fetchData1()
async let result2 = fetchData2()
let combined = await "\(result1) a🎯 Best For
