🎨 Fal.ai MCP Server

A Model Context Protocol (MCP) server that enables Claude Desktop (and other MCP clients) to generate images, videos, music, and audio using Fal.ai models.

✨ Features

• Non-blocking - All operations are truly asynchronous

• 🖼️ Image Generation - Create images using Flux, SDXL, and other models

• 🎬 Video Generation - Generate videos from images or text prompts

• 🎵 Music Generation - Create music from text descriptions

• 🗣️ Text-to-Speech - Convert text to natural speech

• 📝 Audio Transcription - Transcribe audio using Whisper

• ⬆️ Image Upscaling - Enhance image resolution

• 🔄 Image-to-Image - Transform existing images with prompts
