🤔 What is this?

mcp-google-sheets is a Python-based MCP server that acts as a bridge between any MCP-compatible client (like Claude Desktop) and the Google Sheets API. It allows you to interact with your Google Spreadsheets using a defined set of tools, enabling powerful automation and data manipulation workflows driven by AI.

🚀 Quick Start (Using uvx)

Essentially the server runs in one line: uvx mcp-google-sheets@latest.

This cmd will automatically download the latest code and run it. We recommend always using @latest to ensure you have the newest version with the latest features and bug fixes.

1. ☁️ Prerequisite: Google Cloud Setup

   • You must configure Google Cloud Platform credentials and enable the necessary APIs first. We strongly recommend using a Service Account.
   • ➡️ Jump to the Detailed Google Cloud Platform Setup guide below.

2. 🐍 Install uv

   • uvx is part of uv, a fast Python package installer and resolver. Install it if you haven't already:

     # macOS / Linux
     curl -LsSf https://astral.sh/uv/install.sh | sh
     # Windows
     powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
     # Or using pip:
     # pip install uv
     

     Follow instructions in the installer output to add uv to your PATH if needed.

3. 🔑 Set Essential Environment Variables (Service Account Recommended)

   • You need to tell the server how to authenticate. Set these variables in your terminal:
   • (Linux/macOS)

     # Replace with YOUR actual path and folder ID from the Google Setup step
     export SERVICE_ACCOUNT_PATH="/path/to/your/service-account-key.json"
     export DRIVE_FOLDER_ID="YOUR_DRIVE_FOLDER_ID"
     

   • (Windows CMD)

     set SERVICE_ACCOUNT_PATH="C:\path\to\your\service-account-key.json"
     set DRIVE_FOLDER_ID="YOUR_DRIVE_FOLDER_ID"
     

   • (Windows PowerShell)

     $env:SERVICE_ACCOUNT_PATH = "C:\path\to\your\service-account-key.json"
     $env:DRIVE_FOLDER_ID = "YOUR_DRIVE_FOLDER_ID"
     

   • ➡️ See Detailed Authentication & Environment Variables for other options (OAuth, CREDENTIALS_CONFIG).

4. 🏃 Run the Server!

   • uvx will automatically download and run the latest version of mcp-google-sheets:

     uvx mcp-google-sheets@latest
     

   • The server will start and print logs indicating it's ready.

   • 💡 Pro Tip: Always use @latest to ensure you get the newest version with bug fixes and features. Without @latest, uvx may use a cached older version.

5. 🔌 Connect your MCP Client

   • Configure your client (e.g., Claude Desktop) to connect to the running server.
   • Depending on the client you use, you might not need step 4 because the client can launch the server for you. But it's a good practice to test run step 4 anyway to make sure things are set up properly.
   • ➡️ See Usage with Claude Desktop for examples.

You're ready! Start issuing commands via your MCP client.

☁️ Google Cloud Platform Setup (Detailed)

This setup is required before running the server.

1. Create/Select a GCP Project: Go to the Google Cloud Console.
2. Enable APIs: Navigate to "APIs & Services" -> "Library". Search for and enable:
   • Google Sheets API
   • Google Drive API
3. Configure Credentials: You need to choose one authentication method below (Service Account is recommended).

---

🔑 Authentication & Environment Variables (Detailed)

The server needs credentials to access Google APIs. Choose one method:

Method A: Service Account (Recommended for Servers/Automation) ✅

• Why? Headless (no browser needed), secure, ideal for server environments. Doesn't expire easily.
• Steps:
  1. Create Service Account: In GCP Console -> "IAM & Admin" -> "Service Accounts".
     • Click "+ CREATE SERVICE ACCOUNT". Name it (e.g., mcp-sheets-service).
     • Grant Roles: Add Editor role for broad access, or more granular roles (like roles/drive.file and specific Sheets roles) for stricter permissions.
     • Click "Done". Find the account, click Actions (⋮) -> "Manage keys".
     • Click "ADD KEY" -> "Create new key" -> JSON -> "CREATE".
     • Download and securely store the JSON key file.
  2. Create & Share Google Drive Folder:
     • In Google Drive, create a folder (e.g., "AI Managed Sheets").
     • Note the Folder ID from the URL: https://drive.google.com/drive/folders/THIS_IS_THE_FOLDER_ID.
     • Right-click the folder -> "Share" -> "Share".
     • Enter the Service Account's email (from the JSON file client_email).
     • Grant Editor access. Uncheck "Notify people". Click "Share".
  3. Set Environment Variables:
     • SERVICE_ACCOUNT_PATH: Full path to the downloaded JSON key file.
     • DRIVE_FOLDER_ID: The ID of the shared Google Drive folder. (See Ultra Quick Start for OS-specific examples)

Method B: OAuth 2.0 (Interactive / Personal Use) 🧑‍💻

• Why? For personal use or local development where interactive browser login is okay.
• Steps:
  1. Configure OAuth Consent Screen: In GCP Console -> "APIs & Services" -> "OAuth consent screen". Select "External", fill required info, add scopes (.../auth/spreadsheets, .../auth/drive), add test users if needed.
  2. Create OAuth Client ID: In GCP Console -> "APIs & Services" -> "Credentials". "+ CREATE CREDENTIALS" -> "OAuth client ID" -> Type: Desktop app. Name it. "CREATE". Download JSON.
  3. Set Environment Variables:
     • CREDENTIALS_PATH: Path to the downloaded OAuth credentials JSON file (default: credentials.json).
     • TOKEN_PATH: Path to store the user's refresh token after first login (default: token.json). Must be writable.

Method C: Direct Credential Injection (Advanced) 🔒

• Why? Useful in environments like Docker, Kubernetes, or CI/CD where managing files is hard, but environment variables are easy/secure. Avoids file system access.
• How? Instead of providing a path to the credentials file, you provide the content of the file, encoded in Base64, directly in an environment variable.
• Steps:
  1. Get your credentials JSON file (either Service Account key or OAuth Client ID file). Let's call it your_credentials.json.
  2. Generate the Base64 string:
     • (Linux/macOS): base64 -w 0 your_credentials.json
     • (Windows PowerShell):

       $filePath = "C:\path\to\your_credentials.json"; # Use actual path
       $bytes = [System.IO.File]::ReadAllBytes($filePath);
       $base64 = [System.Convert]::ToBase64String($bytes);
       $base64 # Copy this output
       

     • (Caution): Avoid pasting sensitive credentials into untrusted online encoders.
  3. Set the Environment Variable:
     • CREDENTIALS_CONFIG: Set this variable to the full Base64 string you just generated.

       # Example (Linux/macOS) - Use the actual string generated
       export CREDENTIALS_CONFIG="ewogICJ0eXBlIjogInNlcnZpY2VfYWNjb..."
       

Method D: Application Default Credentials (ADC) 🌐

• Why? Ideal for Google Cloud environments (GKE, Compute Engine, Cloud Run) and local development with gcloud auth application-default login. No explicit credential files needed.
• How? Uses Google's Application Default Credentials chain to automatically discover credentials from multiple sources.
• ADC Search Order:
  1. GOOGLE_APPLICATION_CREDENTIALS environment variable (path to service account key) - Google's standard variable
  2. gcloud auth application-default login credentials (local development)
  3. Attached service account from metadata server (GKE, Compute Engine, etc.)
• Setup:
  • Local Development:
    1. Run gcloud auth application-default login --scopes=https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/spreadsheets,https://www.googleapis.com/auth/drive once
    2. Set a quota project: gcloud auth application-default set-quota-project <project_id> (replace <project_id> with your Google Cloud project ID)
  • Google Cloud: Attach a service account to your compute resource
  • Environment Variable: Set GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json (Google's standard)
• No additional environment variables needed - ADC is used automatically as a fallback when other methods fail.

Note: GOOGLE_APPLICATION_CREDENTIALS is Google's official standard environment variable, while SERVICE_ACCOUNT_PATH is specific to this MCP server. If you set GOOGLE_APPLICATION_CREDENTIALS, ADC will find it automatically.

Authentication Priority & Summary

The server checks for credentials in this order:

1. CREDENTIALS_CONFIG (Base64 content)
2. SERVICE_ACCOUNT_PATH (Path to Service Account JSON)
3. CREDENTIALS_PATH (Path to OAuth JSON) - triggers interactive flow if token is missing/expired
4. Application Default Credentials (ADC) - automatic fallback

Environment Variable Summary:

Variable	Method(s)	Description	Default
SERVICE_ACCOUNT_PATH	Service Account	Path to the Service Account JSON key file (MCP server specific).	-
GOOGLE_APPLICATION_CREDENTIALS	ADC	Path to service account key (Google's standard variable).	-
DRIVE_FOLDER_ID	Service Account	ID of the Google Drive folder shared with the Service Account.	-
CREDENTIALS_PATH	OAuth 2.0	Path to the OAuth 2.0 Client ID JSON file.	credentials.json
TOKEN_PATH	OAuth 2.0	Path to store the generated OAuth token.	token.json
CREDENTIALS_CONFIG	Service Account / OAuth 2.0	Base64 encoded JSON string of credentials content.	-
