Claude Desktop Integration

To use this server with Claude Desktop:

1. Open Claude Desktop

2. Go to Settings > Developer

3. Click "Edit Config"

4. Add the following configuration:

"gemini": {
  "command": "node",
  "args": ["path\\to\\dist\\gemini_mcp_server.js"],
  "env": {
    "GEMINI_API_KEY": "gemini_api_key"
  },
  "cwd": "path\\to\\gemini-mcp-server"
}

Replace:

• /path/to/gemini-mcp-server with the absolute path to your repository

• your_api_key_here with your actual Google Gemini API key

The server will now be available in Claude Desktop's MCP server list.

API Implementation

This server uses direct HTTP requests to the Gemini API endpoint. The API request format follows Google's official documentation:

curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash:generateContent?key=GEMINI_API_KEY" \
-H 'Content-Type: application/json' \
-X POST \
-d '{
  "contents": [{
    "parts":[{"text": "Explain how AI works"}]
    }]
   }'

Testing

You can test the direct API implementation using the example script:

node dist/example_direct_api.js "Your prompt here"
