Troubleshooting
No providers configured
Set at least one of OPENAI_API_KEY, XAI_API_KEY, GEMINI_API_KEY, ELEVENLABS_API_KEY, or BFL_API_KEY in the MCP server's env block.
Provider not available for requested media type
Each provider supports different media types (see Provider Capabilities). If you specify a provider that isn't configured (no API key) or doesn't support the requested media type, you'll receive an error. Omit the provider parameter to auto-select from configured providers.
Video generation timeout
Video generation polls for up to 10 minutes. If your video hasn't completed in that window, the request will fail with a timeout error. Try a shorter duration or a simpler prompt.
xAI image generation returned no data
This indicates the xAI API returned an empty response. Check that your XAI_API_KEY is valid and that your prompt does not violate xAI content policies.
Gemini image/video generation failed: 403
Verify your GEMINI_API_KEY has the Generative Language API enabled in Google Cloud Console.
Development
Editor Setup
Replace OPENAI_API_KEY with your provider of choice (XAI_API_KEY, GEMINI_API_KEY, ELEVENLABS_API_KEY, BFL_API_KEY). You can set multiple keys to enable multiple providers.
