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"
      ]
    }
  }
}
