Usage Examples

Health-check endpoint for the MCP Web App

/**
 * Returns a simple response if the supplied accessKey matches.
 */
function doGet(e) {
  const ACCESS_KEY = "sample"; // Must match the key used in your env var
  if (e.parameter.accessKey !== ACCESS_KEY) {
    return ContentService
      .createTextOutput("Invalid accessKey")
      .setMimeType(ContentService.MimeType.TEXT);
  }
  return ContentService
    .createTextOutput("MCP server is running")
    .setMimeType(ContentService.MimeType.TEXT);
}

Deploy this script as a Web App and set MCP_WEB_APPS_URL to the deployment URL with ?accessKey=sample. You can then invoke the tools inside Gemini CLI with the /mcp command.
