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.

Usage

This 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:

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

Library Project Keys and Installation

  1. Open the script editor of the project you just created.
  2. Install MCPApp:
  3. Install ToolsForMCPServer:

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;
  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 an error related to Drive API occurred, please enable Drive API at Advanced Google services.
  • If you want to manage Docs, Sheets, and Slides using the batch update methods of API, please enable Docs API, Sheets API, and Slides 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:

  1. In the script editor, at the top right, click Deploy -> New deployment.
  2. Click Select type -> Web App.
  3. Enter a description for the Web App in the fields under Deployment configuration.
  4. Select "Me" for "Execute as". This is crucial, as it allows the script to run with your permissions to access your Google services.
  5. 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.
  6. Click Deploy.
  7. 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

2. Modify settings.json

To connect the Gemini CLI to your new Apps Script server, you need to edit its settings file. 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.

  1. Replace https://script.google.com/macros/s/###/exec with the Web App URL you copied earlier.
  2. Ensure the accessKey query parameter matches the accessKey you defined in your Google Apps Script (sample in this example).
{
  "theme": "Default",
  "selectedAuthType": "###",
  "mcpServers": {
    "gas_web_apps": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://script.google.com/macros/s/###/exec?accessKey=sample"
      ],
      "env": {}
    }
  }
}
  • "gas_web_apps": A local identifier for your server.
  • "command" and "args": These tell the Gemini CLI how to invoke the mcp-remote tool, which handles the communication with your Web App URL.

When you have never installed mcp-remote, please install it. Ref

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.

  1. Download ggsrun: Get the latest release from the ggsrun releases page. The main repository is here.
  2. Create a Google Cloud Project: Go to the Google Cloud Platform Resource Manager and click CREATE PROJECT.
  3. Enable Drive API: In your new project, navigate to APIs & Services > Enabled APIs & Services. Search for and enable the Drive API.
  4. Create Credentials: Navigate to APIs & Services > Credentials.
  5. Configure OAuth Client ID: Click Create credentials, select OAuth client ID, and choose Web Application.
  6. Set Redirect URI: Under "Authorized redirect URIs," add http://localhost:8080.
  7. 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.
  8. 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 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]

Search Files in Google Drive

Prompt

Search for files with the filename of "sample file" from Google Drive.

Answer

  ✔  search_file_in_google_drive (gas_web_apps MCP Server) {"query":"name = 'sample file'"}

✦ I found a file named "sample file" on Google Drive. It's a Google Sheet, and here's its link:
  https://docs.google.com/spreadsheets/d/###/edit?usp=drivesdk

Explanation

Gemini interpreted the request and selected the search_file_in_google_drive tool from the gas_web_apps MCP server. It constructed the appropriate Google Drive search query (name = 'sample file') and executed the search via Google Apps Script, returning the file metadata.

Show Schedule from Google Calendar

Prompt

Tell me my today's schedule.

Answer

  ✔  search_schedule_on_Google_Calendar (gas_web_apps MCP Server) {"start":"2025-07-03","end":"2025-07-03"}

✦ Today, July 3, 2025, you have two events:
   - 12:00 PM - 1:00 PM: "sample event 1" (Lunch) at Shinagawa Station.
   - 7:00 PM - 8:00 PM: "sample event 2" (Dinner) at Osaka Station.

Explanation

The model used the search_schedule_on_Google_Calendar tool, automatically determining the correct start and end dates for "today". The MCP server fetched the events from Google Calendar, and Gemini summarized the results.

Show Today's Emails

Prompt

Tell me my today's emails from [email protected].

Answer

  ✔  get_messages_by_search_from_Gmail (gas_web_apps MCP Server) {"query":"from:[email protected] after:2025/07/03"}

✦ Here are your emails from [email protected] for today:

   1. From: Tanaike Kanshi <[email protected]>
      Subject: sample mail 2
      Body: This is a sample mail of No.2.

   2. From: Tanaike Kanshi <[email protected]>
      Subject: sample mail 1
      Body: This is a sample mail of No.1.

Explanation

Gemini utilized the get_messages_by_search_from_Gmail tool, correctly formulating a Gmail search query (from:[email protected] after:2025/07/03) to meet the constraints of the prompt.

Send an Email

Prompt

I received a souvenir from my friend Tanaike. Create an email to thank him for it. Tanaike's email address is [email protected].

Answer

  ✔  auto_new_draft_creation_Gmail (gas_web_apps MCP Server) {"obj":[{"body":"Dear Tanaike,\n\nThank you so much for the wonder…
  A draft email was successfully created. The draft ID is "r-###".

  ✔  send_mails_Gmail (gas_web_apps MCP Server) {"draftIds":["r-###"]}
  Message of "Thank you for the souvenir!" was correctly sent.

✦ I have already sent the email to Tanaike thanking him for the souvenir.

The following email was automatically sent to [email protected]:

Dear Tanaike,

Thank you so much for the wonderful souvenir! I really appreciate your
thoughtfulness.

Best regards,
Kanshi Tanaike

Explanation

This prompt required two steps. First, Gemini used auto_new_draft_creation_Gmail to generate the email content and create a draft within Gmail via the MCP server. Second, it immediately used the send_mails_Gmail tool, passing the draft ID from the first step to send the email.

Check Weather and Create a Schedule in Google Calendar

This example demonstrates complex orchestration involving web search and multiple MCP tools. This prompt is similar to one found in this reference: Ref

Prompt

Check tomorrow's weather conditions at 12 PM around Shinagawa Station and exchange 100 US Dollars for Japanese Yen. Under this condition, will we enjoy eating lunch outside for 1 hour at the retrieved location and that day? Finally, create it as a schedule in Google Calendar.

Answer

  ✔  GoogleSearch Searching the web for: "latitude and longitude of Shinagawa Station"
  Search results for "latitude and longitude of Shinagawa Station" returned.
  
  ✔  get_current_date_time (gas_web_apps MCP Server) {"timezone":"Asia/Tokyo"}
  The current date and time are "2025-07-03 11:04:42". Timezone is "Asia/Tokyo".

  ✔  get_exchange_rate (gas_web_apps MCP Server) {"currency_from":"USD","currency_to":"JPY"}
  The raw data from the API is {"amount":1.0,"base":"USD","date":"2025-07-02","rates":{"JPY":144.15}}. The detailed result is as follows. The currency rate at latest from "USD" to "JPY" is 144.15. 
 
  ✔  get_current_weather (gas_web_apps MCP Server) {"date":"2025-07-04 12:00","longitude":139.73917,"latitude":35.62861,"timezo…
  Mainly clear, partly cloudy, and overcast
 
✦ Tomorrow's weather around Shinagawa Station at 12 PM is expected to be mainly clear, partly cloudy, and overcast. The exchange rate for 100 US Dollars is 14415 Japanese Yen (1 USD = 144.15 JPY).

  Given the weather conditions, it might be enjoyable to eat lunch outside, but there's a chance of it being overcast.
 
  ✔  create_schedule_to_Google_Calendar (gas_web_apps MCP Server) {"description":"Lunch at Shinagawa Station. Weather: Mainly c…
  An event was created as Start: 2025-07-04 12:00:00, End: 2025-07-04 13:00:00, Title: Outdoor Lunch at Shinagawa Station, Description: Lunch at Shinagawa Station. Weather: Mainly clear, partly cloudy, and overcast. Exchange rate: 1 USD = 144.15 JPY.
 
✦ The schedule for an outdoor lunch at Shinagawa Station tomorrow, July 4, 2025, from 12:00 PM to 1:00 PM, has been created in your Google Calendar. The description includes the weather forecast (mainly clear, partly cloudy, and overcast) and the exchange rate (1 USD = 144.15 JPY).

The following event was automatically created in Google Calendar:

Date: July 4, 2025, from 12:00 PM to 1:00 PM
Title: Outdoor Lunch at Shinagawa Station
Description: Lunch at Shinagawa Station. Weather: Mainly clear, partly cloudy, and overcast. Exchange rate: 1 USD = 144.15 JPY.

Explanation

This involved a complex chain of actions:

  1. Gemini used the standard GoogleSearch to find the latitude and longitude of Shinagawa Station.
  2. It used the MCP tool get_current_date_time to establish the date.
  3. It used get_exchange_rate to find the USD to JPY conversion.
  4. It used get_current_weather, inputting the coordinates found in step 1 and the date/time.
  5. Gemini synthesized this information to answer the qualitative question about enjoying lunch.
  6. Finally, it used create_schedule_to_Google_Calendar, embedding the retrieved weather and exchange rate information into the event description.

Add Text to an Existing Google Document (or Spreadsheet)

Prompt

Append the following text to the document "sample document 20250703".
<Text>
sample text 1
sample text 2
sample text 3
sample text 4
sample text 5
</Text>

Answer

  ✔  search_file_in_google_drive (gas_web_apps MCP Server) {"query":"sample document 20250703"}
  "isError": true

  ✔  search_file_in_google_drive (gas_web_apps MCP Server) {"query":"name = 'sample document 20250703'"}
     1 files were found.

  ✔  put_values_into_google_docs (gas_web_apps MCP Server) {"text":"sample text 1\nsample text 2\nsample text 3\nsample text 4\…
  Text is appended successfully to Google Docs.

✦ The text has been successfully appended to the document "sample document 20250703".

Explanation

This example demonstrates Gemini's ability to self-correct when using tools.

  1. Initially, Gemini tried searching Google Drive using an invalid query format ({"query":"sample document 20250703"}). The MCP server returned an error ("isError": true).
  2. Gemini recognized the failure and automatically retried the search_file_in_google_drive tool, this time using a valid Drive API query format ({"query":"name = 'sample document 20250703'"}).
  3. Once the file was found, it used put_values_into_google_docs to append the provided text.

Create a New Google Document and Add Text

Prompt

Create a new Google Document and put the following text into the Google Document.
<Text>
sample text 1
sample text 2
sample text 3
sample text 4
sample text 5
</Text>

Answer

  ✔  create_file_to_google_drive (gas_web_apps MCP Server) {"mimeType":"application/vnd.google-apps.document","filename":"New D…
  A file was created on the root folder. The file URL is "https://docs.google.com/document/d/###/edit?usp=drivesdk".

  ✔  put_values_into_google_docs (gas_web_apps MCP Server) {"documentId":"###","text":…
  Text is appended successfully to Google Docs.

✦ I have already created a new Google Document named "New Document 2025-07-03" and put the specified text into it.

Explanation

This required two sequential tools. First, create_file_to_google_drive was used to create a new document; Gemini automatically assigned a relevant filename ("New Document 2025-07-03"). Second, put_values_into_google_docs was used to insert the text into the newly created document ID.

Generate Presentation

This idea and the supporting script are based on "Integrating Gemini and Google Apps Script for Automated Google Slides Presentations". Ref

Prompt

Please create a 3-minute presentation. The title will be "Cooking miso soup". My name is Tanaike. The purpose of the presentation is to explain how to make delicious miso soup.

Answer

  ✔  generate_presentation_with_google_slides (gas_web_apps MCP Server) {"name":"Tanaike","text":"This presentation will guide …
  Presentation was successfully created. The url is "https://docs.google.com/open?id=###".

✦ The presentation "Cooking misosoup" has been created. You can access it at:
  https://docs.google.com/open?id=###

The following presentation is automatically generated in Google Slides.

Explanation

The Gemini CLI passed the request parameters to the generate_presentation_with_google_slides tool on the MCP server.

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.

About

The Gemini CLI confirmed that the MCP server built with Google Apps Script (GAS), a low-code platform, offers immense possibilities. If you've created snippets for GAS, these could be revitalized and/or leveraged in new ways by using them as the MCP server. The Gemini CLI and other MCP clients will be useful in achieving this.
