Help Needed: Transcribing MP3/MP4 Files with Gladia's MCP Server

Hello everyone, I'm trying to create an agent using Gladia's MCP Server to transcribe an MP3 or MP4 file into a text file, but it seems that DUST doesn't support these formats yet. I've also tried using the direct URL of the file, but that doesn't work either. If anyone has any advice or suggestions on how to resolve this, I would be very grateful.
