Gemini CLI with MCP Server: Expanding Possibilities with Google Apps Script

Abstract

The Gemini CLI provides a powerful command-line interface for interacting with Google's Gemini models. By leveraging the Model Context Protocol (MCP), the CLI can be extended with custom tools. This report explores the integration of the Gemini CLI with an MCP server built using Google Apps Script Web Apps. We demonstrate how this combination simplifies authorization for Google Workspace APIs (Gmail, Drive, Calendar, etc.), allowing Gemini to execute complex, multi-step tasks directly within the Google ecosystem. We provide setup instructions and several practical examples showcasing how this integration unlocks significant potential for automation and productivity enhancement.

Introduction

Recently, I published a report titled "Gemini CLI with MCP Server Built by Web Apps of Google Apps Script" (Ref). This initial report highlighted how a Model Context Protocol (MCP) server, developed using Google Apps Script Web Apps, can be integrated with the Gemini CLI.

One of the key advantages of using Google Apps Script is its ability to provide seamless authorization for Google APIs, particularly those within Google Workspace. This significantly reduces the development overhead associated with building applications that interact with Google Workspace services.

Building upon that foundation, this report aims to explore the expanded possibilities when combining the Gemini CLI with an MCP server powered by Google Apps Script Web Apps. We will delve into how this powerful combination facilitates the integration of various tools and services, unlocking an infinite range of potential applications for enhanced productivity and automation within the Google ecosystem.

Current tools

In the current stage (November 14, 2025), the following 160 tools are provided by ToolsForMCPServer for the MCP server.

You can see the descriptions of all tools with the following command on Gemini CLI.

/mcp desc

The next section details deploying the MCP server using Google Apps Script and configuring the Gemini CLI to use it.

Preparing the MCP Server

1. Create a Google Apps Script Project

First, create a new standalone Google Apps Script project. A standalone project is not bound to a specific Google Sheet, Doc, or Form, making it ideal for creating a general-purpose web service. You can create one by visiting script.google.com. Ref

2. Install Libraries

To simplify building the MCP server, we will use pre-built Google Apps Script libraries. These encapsulate the complex MCP handling logic and provide ready-to-use tools, keeping the main script clean.

This sample uses two Google Apps Script libraries:

MCPApp: Manages the MCP server lifecycle and communication protocols.
ToolsForMCPServer: Provides a suite of pre-built tools for interacting with Google Workspace services (Gmail, Drive, Calendar, etc.).

Library Project Keys and Installation

Open the script editor of the project you just created.

3. Script

Please copy and paste the following script into the script editor (replacing any existing code) and save the project.

This is a basic script for using this library.

const apiKey = "###"; // API key for Gemini API

/**
 * This function is automatically run when the MCP client accesses Web Apps.
 */
const doPost = (e) => main(e);

function main(eventObject) {
  const m = ToolsForMCPServer;

  m.apiKey = apiKey; // This is an API key for using Gemini API.
  // m.model = "models/gemini-2.5-flash"; // If you change model, use this.
  // m.defaultCalendarId = "###"; // If you want to use the specific calendar, please use this.
  // m.enableBaseTools = false; // Disable base tools
  // m.enableClassroomTools = false; // Disable tools for managing Google Classroom
  // m.enablePeopleTools = false; // Disable tools for managing Google People
  // m.enableAnalyticsTools = false; // Disable tools for managing Google Analytics
  // m.enableMapsTools = false; // Disable tools for managing Google Maps
  // m.enableFileSearch = false; // Disable tools for managing File Search

  const object = { eventObject, items: m.getTools() };
  return new MCPApp.mcpApp({ accessKey: "sample" })
    .setServices({ lock: LockService.getScriptLock() })
    .server(object);
}

Note:

If you intend to use the following tools, you must uncomment the apiKey line in the script and provide a valid API key for the Gemini API.
- generate_roadmap_to_google_sheets: Creates a roadmap in Google Sheets.
- generate_description_on_google_drive: Generates and sets a description for a file on Google Drive.
- generate_image_on_google_drive: Generates an image from a prompt and saves it to Google Drive.
- summarize_file_on_google_drive: Summarizes a file stored on Google Drive.
- description_web_site: Provides descriptions of websites given their URLs.
If you want to use the specific Google Calendar, please set defaultCalendarId.

APIs

If an error related to Drive API occurred, please enable Drive API at Advanced Google services.
If you want to manage Docs, Sheets, Slides, and Calendars using the batch update methods of API, please enable Docs API, Sheets API, Slides API, and Calendar API at Advanced Google services.
If you want to manage Google Classroom and Google People, please enable the Google Classroom API and the Google People API at Advanced Google services.
If you want to retrieve the drive activity, please enable Drive Activity API at Advanced Google services.
If you want to use Google Analytics, please enable Google Analytics Admin API and Google Analytics Data API at Advanced Google services.

Show all tools

When this script is run, all tools in this library are shown as a JSON object.

function showAlltools() {
  const res = ToolsForMCPServer.getToolList();
  console.log(res);
}

Filter tools

When you want to use the specific tools, you can also use the following script.

This script uses only the tool get_exchange_rate.

function main(eventObject) {
  const enables = ["get_exchange_rate"];

  const m = ToolsForMCPServer;
  m.apiKey = apiKey;
  const object = { eventObject, items: m.getTools({ enables }) };
  return new MCPApp.mcpApp({ accessKey: "sample" })
    .setServices({ lock: LockService.getScriptLock() })
    .server(object);
}

This script uses all tools except for the tool get_exchange_rate.

function main(eventObject) {
  const disables = ["get_exchange_rate"];

  const m = ToolsForMCPServer;
  m.apiKey = apiKey;
  const object = { eventObject, items: m.getTools({ disables }) };
  return new MCPApp.mcpApp({ accessKey: "sample" })
    .setServices({ lock: LockService.getScriptLock() })
    .server(object);
}

4. Deploy Web Apps

To allow the Gemini CLI to communicate with our script, we must deploy it as a Web App. This creates a unique URL that acts as our MCP server endpoint.

You can find detailed information in the official documentation.

Please follow these steps to deploy the Web App in the script editor:

In the script editor, at the top right, click Deploy -> New deployment.
Click Select type -> Web App.
Enter a description for the Web App in the fields under Deployment configuration.
Select "Me" for "Execute as". This is crucial, as it allows the script to run with your permissions to access your Google services.
Select "Anyone" for "Who has access". This makes the URL callable from the internet. Access is controlled by the unguessable URL and the accessKey defined in the script.
Click Deploy.
After authorizing the necessary scopes, copy the Web app URL. It will look similar to https://script.google.com/macros/s/###/exec. This is your MCP server endpoint.

Important: When you modify the Apps Script code, you must create a new deployment version to publish the changes. Click Deploy > Manage deployments, select your active deployment, click the pencil icon, and choose "New version" from the Version dropdown. More info here.

Preparing Gemini CLI

1. Install Gemini CLI

Follow the official documentation to install the Gemini CLI on your system. Ref

There are 2 patterns for using this MCP server using Gemini CLI and other AI agents as follows.

2A. Pattern 1

In this pattern, Gemini CLI is directly connected to the MCP server built by Google Apps Script Web Apps.

To connect the Gemini CLI to your new Apps Script server, you need to edit its settings file settings.json. This file is typically located at ~/.gemini/settings.json on macOS/Linux or %USERPROFILE%\.gemini\settings.json on Windows.

Add the mcpServers configuration block as shown below.

Replace https://script.google.com/macros/s/###/exec with the Web App URL you copied earlier.
Ensure the accessKey query parameter matches the accessKey you defined in your Google Apps Script (sample in this example).

{
  "theme": "Default",
  "selectedAuthType": "gemini-api-key",
  "mcpServers": {
    "gas_web_apps": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://script.google.com/macros/s/###/exec?accessKey=sample"
      ],
      "env": {}
    }
  },
  "disableAutoUpdate": true
}

{
  "theme": "Default",
  "selectedAuthType": "###",
  "mcpServers": {
    "gas_web_apps": {
      "httpUrl": "https://script.google.com/macros/s/###/exec?accessKey=sample",
      "description": "MCP server built by Google Apps Script Web Apps"
    }
  }
}

"gas_web_apps": A local identifier for your server.
"httpUrl": Your Web Apps URL. In the current stage, when this is used, an error might occur. At that time, use mcp-remote.
If you use mcp-remote, please install it. Ref

If an error like Request timed out occurs, please add timeout and use GEMINI_TIMEOUT as follows.

{
  "theme": "Default",
  "selectedAuthType": "gemini-api-key",
  "mcpServers": {
    "gas_web_apps": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://script.google.com/macros/s/###/exec?accessKey=sample"
      ],
      "env": {},
      "timeout": 300000
    }
  },
  "disableAutoUpdate": true
}

GEMINI_TIMEOUT=300 # Seconds

2B. [NEW] Pattern 2 (Added on October 15, 2025)

Now, ToolsForMCPServer can be used as a Gemini extension. You can see how to install it at https://github.com/tanaikech/ToolsForMCPServer-extension.

3. Transfer file content (Added on July 9, 2025)

Recently, I published a report titled "Processing File Content Using Gemini CLI with an MCP Server Built by Google Apps Script" Ref. In this report, I concluded that using the Drive API in the background is more effective for transferring file content between Gemini CLI and Google Drive than embedding base64 data directly in the prompt. Therefore, to facilitate this effective transfer, I use ggsrun, a CLI tool.

3.1. `ggsrun` Setup Guide

To use this method, you first need to set up ggsrun.

Download ggsrun: Get the latest release from the ggsrun releases page. The main repository is here.
Create a Google Cloud Project: Go to the Google Cloud Platform Resource Manager and click CREATE PROJECT.
Enable Drive API: In your new project, navigate to APIs & Services > Enabled APIs & Services. Search for and enable the Drive API.
Create Credentials: Navigate to APIs & Services > Credentials.
Configure OAuth Client ID: Click Create credentials, select OAuth client ID, and choose Web Application.
Set Redirect URI: Under "Authorized redirect URIs," add http://localhost:8080.
Create and Download Credentials: Click Create, then Download JSON. Important: Rename the downloaded file to client_secret.json and place it in your working directory.
Authenticate ggsrun:

8-1. Open your terminal in the directory containing client_secret.json.

8-2. Run the command ggsrun auth.

8-3. Copy the URL displayed in the terminal, paste it into your browser, and authorize the requested scopes.

8-4. Copy the authorization code from your browser's address bar and paste it back into the terminal.

To verify the setup, run ggsrun di to display information about your Google Drive.

3.2. Configuring Gemini CLI for `ggsrun`

To enable the Gemini CLI to use ggsrun, add the following tool definitions to your GEMINI.md file. This file is typically located at ~/.gemini/GEMINI.md on macOS/Linux or %USERPROFILE%\.gemini\GEMINI.md on Windows.

# Transferring file content between local PC and Google Drive using ggsrun

* GitHub Repository: [https://github.com/tanaikech/ggsrun](https://github.com/tanaikech/ggsrun)
* To download a file from Google Drive by filename, use this command:
  ```bash
  ggsrun d -f [filename]
  ```
* To download a file from Google Drive by file ID, use this command:
  ```bash
  ggsrun d -i [fileId]
  ```
* To download a file from Google Drive by a file ID by converting mimeType, use this command:
  ```bash
  ggsrun d -i [fileId] -e [extension]
  ```
  [extension] is the file extension. For example, when you want to download the file in PDF format and TEXT format, use "pdf" and "txt", respectively.
* To upload files from the local PC to the root directory of Google Drive, use this command:
  ```bash
  ggsrun u -f "[filename1],[filename2],,,"
  ```
* To upload files from the local PC to a specific directory of Google Drive, use this command:
  ```bash
  ggsrun u -p [folderId] -f "[filename1],[filename2],,,"
  ```
* To search for files and folders on Google Drive, use this command:
  ```bash
  ggsrun sf -q "[search query of Drive API v3 ([https://developers.google.com/workspace/drive/api/guides/search-shareddrives](https://developers.google.com/workspace/drive/api/guides/search-shareddrives))]"
  ```
* To search for files and folders on Google Drive, use this command:
  ```bash
  ggsrun ls -s [filename]
  ```

Sandbox

Have you ever faced a task that isn’t part of your routine but is tedious to do manually, like, ‘I need to add a “[For Review]” prefix to the titles of all Google Docs in a specific folder this afternoon’? Or perhaps you’ve thought, ‘I want to use AI to work with my spreadsheets, but I’m concerned about the security implications of granting a tool full access to my Google Drive’? At that time, I can recommend using "fake-sandbox". You can see the following articles.

Sample prompts

Sample prompts using ToolsForMCPServer

Summary

The examples above demonstrate that combining the Gemini CLI with an MCP server built using Google Apps Script Web Apps enables powerful automation across Google Workspace. By leveraging Google Apps Script's inherent authorization capabilities, we can easily give Gemini access to Gmail, Calendar, Drive, Docs, Sheets, and Slides.

The samples provided represent only a small subset of what is possible. The ToolsForMCPServer library includes many functions derived from previously developed Google Apps Script utilities. Furthermore, because the MCP server is simply a Google Apps Script project, developers can easily incorporate their own existing GAS snippets as new tools for the Gemini CLI. As this MCP server is updated with more tools, the potential for complex, AI-driven automation within the Google ecosystem becomes nearly limitless.

Appendix

What should we do in this situation?

When Gemini CLI is launched and an error Error connecting to MCP server 'gas_web_apps': Connection failed for 'gas_web_apps': MCP error -32000: Connection closed occurs, please redeploy Web Apps to reflect the latest script and try it again.

Add custom tools and prompts

You might want to add your custom tools and promts to the MCP server. At that time, please refer to the following script.

/**

 */
const doPost = (e) => main(e);

function main(eventObject) {
  const m = ToolsForMCPServer;
  m.apiKey = apiKey;
  const object = { eventObject, items: [...m.getTools(), ...getCustomTools()] };
  return new MCPApp.mcpApp({ accessKey: "sample" })
    .setServices({ lock: LockService.getScriptLock() })
    .server(object);
}

Approach for reducing startup speed for loading MCP server

In order to reduce the process time for loading the MCP server when Gemini CLI is run, I created a wrapper as an approach. When you use this approach, please deploy Google Apps Script Web Apps with ToolsForMCPServer and MCPApp. After it, please do the following steps.

Now, implement the Node.js wrapper to accelerate the startup.

Create a new workspace directory and navigate into it.
Install the necessary libraries: npm install @modelcontextprotocol/sdk zod@3.
Download the two required script files wrapped_gas_web_apps.js and tools.js from my repository.
Modify settings.json to use the Node.js wrapper. Replace {your path} with the absolute path to wrapped_gas_web_apps.js.

{
  "theme": "Default",
  "selectedAuthType": "### your setting ###",
  "mcpServers": {
    "wrapped_gas_web_apps": {
      "command": "node",
      "args": ["{your path}/wrapped_gas_web_apps.js"]
    }
  }
}

Run $ gemini again. You should observe a significantly faster startup. In my tests, the startup time was reduced by approximately 15 times. While the performance of individual tool execution remains the same, the improved startup time makes the CLI much more practical and user-friendly.
