• src/tools/server-actions.ts:7-34 (registration)

  The 'server_restart' tool is registered as part of a loop in 'registerServerActionTools'. It uses a generic handler that executes a POST request to the Crafty API using the 'restart_server' action.

  export function registerServerActionTools(server: McpServer, client: CraftyClient): void {
    const actions: Array<{ name: string; action: string; description: string }> = [
      { name: "server_start", action: "start_server", description: "Start a Minecraft server" },
      { name: "server_stop", action: "stop_server", description: "Stop a Minecraft server (sends configured stop command)" },
      { name: "server_restart", action: "restart_server", description: "Restart a Minecraft server" },
      { name: "server_kill", action: "kill_server", description: "Force-kill a Minecraft server process immediately" },
      { name: "server_backup", action: "backup_server", description: "Trigger an immediate backup of a Minecraft server's files" },
      { name: "server_update_executable", action: "update_executable", description: "Update the server jar/executable from the configured download URL" },
      { name: "server_clone", action: "clone_server", description: "Clone an existing Minecraft server (server must not be running)" },
    ];
  
    for (const { name, action, description } of actions) {
      server.tool(
        name,
        description,
        serverIdSchema,
        async ({ server_id }) => {
          try {
            const data = await client.post(`/servers/${server_id}/action/${action}`);
            return { content: [{ type: "text", text: JSON.stringify(data, null, 2) }] };
          } catch (error) {
            const msg = error instanceof Error ? error.message : String(error);
            return { content: [{ type: "text", text: `Error: ${msg}` }], isError: true };
          }
        }
      );
    }
  }
