MCP Server

The mcp-server module uses the Kotlin MCP SDK to expose an MCP tools endpoint (returning player/fixture info) that can for example be plugged in to Claude Desktop as shown below. That module uses same KMP shared code.

To integrate the MCP server with Claude Desktop for example you need to firstly run gradle shadowJar task and then select "Edit Config" under Developer Settings and add something like the following (update with your path)

{
  "mcpServers": {
    "fantasy-premier-league": {
      "command": "java",
      "args": [
        "-jar",
        "/Users/john.oreilly/github/FantasyPremierLeague/mcp-server/build/libs/serverAll.jar",
        "--stdio"
      ]
    }
  }
}

UI tests

There's a Maestro UI test flow shared by the Android and iOS clients, run by CI on an emulator and a simulator (e.g. maestro test -e APP_ID=dev.johnoreilly.fantasypremierleague maestro/FantasyPremierLeague.flow).
