SwiftMCP

A Swift implementation of the Model Context Protocol (MCP) for AI agent interactions.

Overview

SwiftMCP is a Model Context Protocol (MCP) implementation in Swift, consisting of both server and client components.

Requirements

• Swift 6.2+
• iOS 26+ / macOS 26+
• Xcode 26+

Project Structure

The project is organized into two main components:

• SwiftMCPServer: The server implementation
• SwiftMCPClient: The client implementation

Dependencies

• MCP Swift SDK

Installation

1. Clone the repository:

git clone <repo>
cd SwiftMCP

2. Build the project:

swift build

Server

The SwiftMCP server component provides a Model Context Protocol server implementation in Swift. It enables AI agents to interact with Swift applications using the standard MCP protocol.

Features

• Built with Swift 6.2+
• Implements MCP protocol over standard I/O
• Includes support for logging, prompts, resources, and tools
• Designed for iOS 26+ and macOS 26+

Getting Started

1. Build the server:

swift build --product SwiftMCPServer

2. Run the server:

swift run SwiftMCPServer

Server Component Details

The server component (SwiftMCPServer) is responsible for:

• Handling incoming MCP connections
• Managing model context
• Processing client requests
• Maintaining state synchronization

Location: SwiftMCPServer/Sources

Client

The SwiftMCP client component allows Swift applications to connect to and interact with MCP-compatible AI agents.

Features

• Built with Swift 6.2+
• Implements MCP client over standard I/O
• Designed for iOS 26+ and macOS 26+
• Simple API for initializing and communicating with MCP servers

Getting Started

1. Build the client:

swift build --product SwiftMCPClient

2. Run the client:

swift run SwiftMCPClient

Client Component Details

The client component (SwiftMCPClient) provides:

• Connection management to MCP server
• Model context synchronization
• Real-time updates handling
• Client-side state management
