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" } } ```
