@modelcontextprotocol/server-gmail-drive MCP Server: Gmail and Drive Integration

Overview: What is @modelcontextprotocol/server-gmail-drive MCP Server?

The @modelcontextprotocol/server-gmail-drive MCP server is a robust adapter designed to enable seamless integration between various AI applications, tools, and end-user data by providing a standardized protocol known as the Model Context Protocol (MCP). This server specifically focuses on facilitating interactions with Google's Gmail and Drive services. By leveraging this MCP server, developers can connect their AI applications with real-time access to user emails and files stored in Google Drive. The server ensures that AI applications like Claude Desktop, Continue, Cursor, and others can interact with these tools through a familiar and well-defined API, promoting interoperability and enhancing the overall user experience.

🔧 Core Features & MCP Capabilities

The @modelcontextprotocol/server-gmail-drive MCP server offers several core features and MCP capabilities that make it an indispensable tool for integrating AI applications:

• Secure Authentication: The server supports OAuth 2.0 authentication using Google credentials, ensuring secure access to users' Gmail and Drive accounts.
• Real-time Data Fetching: Implement real-time data fetching mechanisms to keep the AI application updated with changes in user emails and files within Google Drive.
• API Compliance: Adheres strictly to the Model Context Protocol (MCP), providing a consistent interface for various MCP clients such as Claude Desktop, Continue, and Cursor.

API Compliance Details

The server implements the Model Context Protocol, which defines key functions for authenticating with services like Gmail and Drive. This includes endpoints for:

• Authentication (/auth/oauth): Initiates OAuth 2.0 authentication and returns necessary tokens for accessing user data.
• Data Retrieval (/data/email, /data/drive): Provides real-time access to emails and files stored in Google accounts.

Real-time Email Analysis for Businesses

Developers can use @modelcontextprotocol/server-gmail-drive to create an application that analyzes real-time email data from users' Google accounts. This can be particularly useful for businesses, where automatic processing of emails can enhance productivity and streamline communication.

# Example AI Workflow: Email Sentiment Analysis
import requests

def fetch_emails():
    response = requests.get('http://localhost:3000/data/email')
    return response.json()

def analyze_sentiment(emails):
    for email in emails:
        # Process each email to calculate sentiment score
        pass

Automated Backup and Sync for Important Documents

Developers can also build applications that automatically back up or sync important documents from Google Drive. This ensures users' data remains safe and easily accessible, facilitating quick recovery or collaborative editing.

# Example AI Workflow: Automatic Document Backup
import os
from google.auth.transport.requests import Request
from googleapiclient.http import MediaIoBaseDownload

def download_files():
    # Authenticate and prepare to download files
    creds = google.auth.load_credentials()

    response = requests.get('http://localhost:3000/data/drive/download')
    file_id = response.json()['fileId']

    request = drive_service.files().get_media(fileId=file_id)
    fh = io.BytesIO()
    downloader = MediaIoBaseDownload(fh, request)
    done = False
    while not done:
