Quick Start

Set the API key for at least one provider. Most users only need one — add more to access additional providers.

# Using OpenAI
claude mcp add multimodal-mcp -e OPENAI_API_KEY=sk-... -- npx -y @r16t/multimodal-mcp@latest

# Or using xAI
# claude mcp add multimodal-mcp -e XAI_API_KEY=xai-... -- npx -y @r16t/multimodal-mcp@latest

# Or using Gemini
# claude mcp add multimodal-mcp -e GEMINI_API_KEY=AIza... -- npx -y @r16t/multimodal-mcp@latest

# Or using ElevenLabs (audio + transcription)
# claude mcp add multimodal-mcp -e ELEVENLABS_API_KEY=xi-... -- npx -y @r16t/multimodal-mcp@latest

# Or using BFL/FLUX (images)

Troubleshooting

No providers configured

[config] No provider API keys detected

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

npm run build      # Compile TypeScript to build/
npm test           # Run tests with Vitest
npm run lint       # Lint and auto-fix with ESLint
npm run typecheck  # Type-check without emitting
npm run dev        # Watch mode for TypeScript compilation

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.
