Prerequisites

1. Node.js 18+ installed

2. Google Cloud Project with Keep API enabled

3. OAuth2 credentials from Google Cloud Console

Setup Instructions

1. Google Cloud Setup

1. Go to Google Cloud Console

2. Create a new project or select an existing one

3. Enable the Google Keep API:

   • Go to "APIs & Services" > "Library"

   • Search for "Google Keep API"

   • Click on it and click "Enable"

4. Create OAuth2 credentials:

   • Go to "APIs & Services" > "Credentials"

   • Click "Create Credentials" > "OAuth client ID"

   • Choose "Desktop app" as Application type

   • Give it a name (e.g., "Google Keep MCP")

   • Copy the Client ID and Client Secret

   • Note the redirect URI (usually http://localhost for desktop apps)

2. Installation

# Clone the repository
cd google_notes_mcp/mcp

# Install dependencies
npm install

# Build the TypeScript code
npm run build

# Copy the .env.example to .env
cp .env.example .env

# Edit .env and add your Google OAuth2 credentials:
# - GOOGLE_CLIENT_ID
# - GOOGLE_CLIENT_SECRET
# - GOOGLE_REDIRECT_URI (optional, defaults to http://localhost)

3. First-time Authentication

When you run the server for the first time, it will:

1. Print an authorization URL to the console

2. Open this URL in your browser

3. Sign in with your Google account

4. Grant permissions for Google Keep access

5. Copy the authorization code from the browser

6. Paste it back in the terminal

This will save a token.json file for future use.

4. MCP Configuration

Add this server to your MCP client configuration (e.g., for Claude Desktop):

For Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "google-keep": {
      "command": "node",
      "args": [
        "C:/Users/your-username/Desktop/google_notes_mcp/mcp/dist/index.js"
      ],
      "env": {
        "GOOGLE_CLIENT_ID": "your-client-id.apps.googleusercontent.com",
        "GOOGLE_CLIENT_SECRET": "your-client-secret",
        "GOOGLE_REDIRECT_URI": "http://localhost"
      }
    }
  }
}

Or if you've installed it globally:

{
  "mcpServers": {
    "google-keep": {
      "command": "google-keep-mcp",
      "env": {
        "GOOGLE_CLIENT_ID": "your-client-id.apps.googleusercontent.com",
        "GOOGLE_CLIENT_SECRET": "your-client-secret",
        "GOOGLE_REDIRECT_URI": "http://localhost"
      }
    }
  }
}

Troubleshooting

Authentication Issues

• Make sure your credentials.json file is valid

• Delete token.json and re-authenticate if you're having permission issues

• Ensure the Google Keep API is enabled in your Google Cloud project

API Limitations

• Google Keep API has rate limits

• Some features may require additional scopes or permissions

Security Notes

• Never commit .env or token.json to version control

• Keep your OAuth2 credentials (Client ID and Client Secret) secure

• Always use environment variables for sensitive configuration

• The Client Secret should be kept confidential
