Very basic example of an MCP server using

• https://github.com/hummingbird-project/hummingbird
• https://github.com/modelcontextprotocol/swift-sdk
• https://github.com/orlandos-nl/SSEKit

note: currently using a fork of modelcontextprotocol/swift-sdk that adds needed code to support this. Will update as it makes its way back into main repo

Run the example app as you would any hummingbird app

swift run ExampleMCPApp

run the standard MCP Inspector

npx @modelcontextprotocol/inspector

Set transport type to Streamable HTTP and connect to: http://127.0.0.1:8080/mcp/streamer

Usage:

    router.addRoutes(
        StreamableMCPController(path:"mcp/streamer",
                                stateful: true,
                                jsonResponses: false) {
                                    return await Server.configured()
                                }.endpoints
    )

The closure is how a server instance is created.
