mcp-client-example

This Swift-based MCP server example demonstrates how to implement a Model Context Protocol (MCP) client in a native Swift environment. It provides a minimal, runnable Swift-based MCP server that showcases how to structure MCP commands, expose model context operations, and integrate with the MCP ecosystem. To use it, clone the repository, build the Swift source, and run the server to begin handling MCP requests. The example illustrates how to wire up MCP endpoints, define context-driven operations, and test interactions against a local or remote MCP client.

Once running, you can interact with the MCP server using the standard MCP request/response patterns described in the MCP specification. Typical workflows include creating, updating, and querying model context entries, as well as handling context mutations in a Swift-native environment. The example focuses on clarity and portability for Swift developers exploring MCP integration in iOS or server-side Swift projects.

Prerequisites:

• Swift toolchain installed (Swift 5.x+)
• macOS or Linux environment capable of building Swift projects
• Basic familiarity with the Swift Package Manager (SwiftPM) or Xcode for building Swift sources

Installation steps:

1. Clone the repository git clone https://github.com/your-org/mcp-client-example.git cd mcp-client-example

2. Install dependencies (if using SwiftPM) swift package resolve

3. Build the server swift build -c release

4. Run the server .build/release/mcp-client-example

5. Verify operation

   • Connect an MCP client to the running server endpoint and issue MCP requests as documented in the README or accompanying docs.

If you’re using Xcode, open the project, set the appropriate scheme (mcp-client-example), and run the target to launch the server in the Xcode environment.

Notes and tips:

• Ensure you have the correct Swift toolchain installed for your platform.
• The example is intended for educational purposes and may require adjustments to integrate with your MCP environment or specific MCP version.
• If the server doesn’t start, check for port conflicts or missing dependencies in your Swift toolchain.
• Since MCP is protocol-focused, you may need to implement or adapt model context operations to reflect your data models.
• If environment-specific configuration is required, consider extending the mcp_config with relevant environment variables and runtime flags.
