• Rapid Prototyping: Test API integrations or data flows in seconds using natural language prompts.
• Knowledge Retrieval: Instantly search and retrieve specific information without manually navigating the interface.

⚙️ Installation & Configuration

Prerequisites

• Node.js (v18+) or Python (v3.10+) installed locally.
• Claude Desktop, Cursor, or another MCP-compatible client.

Step 1: Install the Server

```bash

Recommended: Run directly via npx (no global install needed)

npx -y GongRzhe/Gmail-MCP-Server

Alternative: Clone and run locally

git clone https://github.com/GongRzhe/Gmail-MCP-Server.git cd Gmail-MCP-Server npm install # or pip install -r requirements.txt ```

Step 2: Update Your MCP Config

Add the following to your claude_desktop_config.json (Mac: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\) or .cursor/mcp.json:

```json { "mcpServers": { "gmail-mcp-server": { "command": "npx", "args": ["-y", "GongRzhe/Gmail-MCP-Server"] } } } ``` (Note: Restart your AI client after saving the configuration file.)

⚙️ Advanced Configuration Options

For production environments, you may need to customize the server behavior. You can pass environment variables in your MCP config:

```json { "mcpServers": { "Gmail-MCP-Server": { "command": "npx", "args": ["-y", "GongRzhe/Gmail-MCP-Server"], "env": { "API_KEY": "your_api_key_here", "TIMEOUT_MS": "30000" } } } } ``` Note: Always use environment variables for sensitive credentials. Never hardcode API keys directly in the JSON.

Once connected, try these high-value prompts in Claude or Cursor:

1. "Use Gmail-MCP-Server to extract structured data or automate a specific general workflow."
2. "Configure the Gmail-MCP-Server MCP server to optimize for speed and reliability."
3. "Analyze the output from Gmail-MCP-Server and format it into a comprehensive Markdown report."
