Quick Start

1. Get Gemini API Key

• Visit Google AI Studio
• Create a new API key
• IMPORTANT: Keep your API key secure and never commit it to version control

1. Configure Your MCP Client

Claude Desktop

Config location:

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

``json { "mcpServers": { "gemini": { "type": "stdio", "command": "npx", "args": ["-y", "github:aliargun/mcp-server-gemini"], "env": { "GEMINI_API_KEY": "your_api_key_here" } } } } ``

Cursor

Add to Cursor's MCP settings: ``json { "gemini": { "type": "stdio", "command": "npx", "args": ["-y", "github:aliargun/mcp-server-gemini"], "env": { "GEMINI_API_KEY": "your_api_key_here" } } } ``

Windsurf

Configure in Windsurf's MCP settings following their documentation.

Other MCP Clients

Use the standard MCP stdio configuration: ``json { "type": "stdio", "command": "npx", "args": ["-y", "github:aliargun/mcp-server-gemini"], "env": { "GEMINI_API_KEY": "your_api_key_here" } } ``

1. Restart Your MCP Client

How to Use

Once configured, you can use natural language in your MCP client to access Gemini's capabilities:

Basic Commands

"Use Gemini to explain quantum computing"
"Analyze this image with Gemini"

Common Issues

1. Connection Issues

• Ensure your MCP client is properly restarted
• Check the client's logs (e.g., ~/Library/Logs/Claude/mcp-server-gemini.log for Claude Desktop on Mac)
• Verify internet connection
• See [Troubleshooting Guide](docs/troubleshooting.md)

1. API Key Problems

• Verify API key is correct
• Check API key has proper permissions
• Ensure the key is set in the environment variable
• See [Setup Guide](docs/claude-desktop-setup.md)

Security

• API keys are handled via environment variables only
• Never commit API keys to version control
