## Description
Multi-provider media generation — images, video, audio, and transcription via a unified interface

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "multimodal": {
    "command": "npx",
    "args": ["-y","multimodal"]
  }
}
```

## Documentation & README

# multimodal-mcp

Multi-provider media generation MCP server. Generate images, videos, audio, and transcriptions from text prompts using OpenAI, xAI, Gemini, ElevenLabs, and BFL (FLUX) through a single unified interface.

## Features

- 🎨 **Image Generation** — Generate images via OpenAI (gpt-image-1), xAI (grok-imagine-image), Gemini (imagen-4), or BFL (FLUX Pro 1.1)
- ✏️ **Image Editing** — Edit images via OpenAI, xAI, Gemini, or BFL (FLUX Kontext)
- 🎬 **Video Generation** — Generate videos via OpenAI (sora-2), xAI (grok-imagine-video), or Gemini (veo-3.1)
- 🔊 **Audio Generation** — Text-to-speech via OpenAI (tts-1), Gemini, or ElevenLabs (Flash v2.5). Sound effects via ElevenLabs
- 🎙️ **Audio Transcription** — Speech-to-text via OpenAI (Whisper) or ElevenLabs (Scribe)
- 🔄 **Auto-Discovery** — Automatically detects configured providers from environment variables
- 🎯 **Provider Selection** — Auto-selects or explicitly choose a provider per request
- 📁 **File Output** — Saves all generated media to disk with descriptive filenames

## Quick Start

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

```bash
# 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)
# claude mcp add multimodal-mcp -e BFL_API_KEY=... -- npx -y @r16t/multimodal-mcp@latest
```

## 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](#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

```bash
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.
