• src/tools/server-tools.ts:106-124 (handler)

  The `validate_server` tool handler, which invokes `manager.validate()` and returns a summary of the server configuration and validation status.

  server.tool(
    "validate_server",
    "Check if the server directory, JAR file, and EULA are properly configured.",
    {},
    async () => {
      const { valid, errors } = manager.validate();
      const config = manager.getConfig();
      const lines = [
        `Server Directory: ${manager.getServerDir()}`,
        `Server JAR: ${manager.getServerJarPath()}`,
        `RCON: ${config.rconHost}:${config.rconPort}`,
        `Java: ${config.javaPath}`,
        `JVM Args: ${config.jvmArgs.join(" ")}`,
        ``,
        valid ? "✅ All checks passed." : `❌ Issues found:\n${errors.map((e) => `  - ${e}`).join("\n")}`,
      ];
      return { content: [{ type: "text", text: lines.join("\n") }] };
    }
  );
