  "gemini": {
    "command": "npx",
    "args": ["-y", "@rlabs-inc/gemini-mcp"],
    "env": {

    }
  }
}

Troubleshooting

Rate Limits (429 Errors)

If you're hitting rate limits on the free tier:

Set GEMINI_MODEL=gemini-3-flash-preview to use Flash for init (higher limits)
Or upgrade to a paid plan

Connection Issues

Verify your API key at Google AI Studio
Check server status: claude mcp list
Try with verbose logging: VERBOSE=true

Image/Video Issues

Ensure your API key has access to image/video generation
Check output directory permissions
Files save to GEMINI_OUTPUT_DIR (default: ./gemini-output)
For 4K images, generation takes longer

Manual Installation

# Using bun
bun install -g @rlabs-inc/gemini-mcp

Claude Code Configuration

config.json

{
  "gemini": {
    "command": "npx",
    "args": ["-y", "@rlabs-inc/gemini-mcp"],
    "env": {
      "GEMINI_API_KEY": "your-api-key",
      "GEMINI_OUTPUT_DIR": "/path/to/save/files"
    }
  }
}

If you must use a proxy to establish a connection to gemini, replace xxxx with your actual proxy port:

config.json

{
  "gemini": {
    "command": "npx",
    "args": ["-y", "@rlabs-inc/gemini-mcp"],
    "env": {
      "GEMINI_API_KEY": "your-api-key",
      "GEMINI_OUTPUT_DIR": "/path/to/save/files",
      "HTTP_PROXY": "http://127.0.0.1:xxxx",
      "HTTPS_PROXY": "http://127.0.0.1:xxxx"
    }
  }
}

Troubleshooting

Rate Limits (429 Errors)

If you're hitting rate limits on the free tier:

Set GEMINI_MODEL=gemini-3-flash-preview to use Flash for init (higher limits)
Or upgrade to a paid plan

Connection Issues

Verify your API key at Google AI Studio
Check server status: claude mcp list
Try with verbose logging: VERBOSE=true

Image/Video Issues

Ensure your API key has access to image/video generation
Check output directory permissions
Files save to GEMINI_OUTPUT_DIR (default: ./gemini-output)
For 4K images, generation takes longer
