Overview

AI-generated overview

Transcribes direct audio or video file links into text using your own Deepgram, AssemblyAI, Groq or OpenAI key, via an Apify actor.

What you can do
  • Transcribe direct audio or video file links with a chosen speech-to-text provider and your own API key
  • Return one row per file with the transcript, timestamped segments, detected language and duration
  • Optionally label speakers (diarization) and set a model or language code
  • Check up to 3 files for free without a key, and refuse platform pages such as YouTube or TikTok
When to use it
Useful when you have direct, login-free links to recordings such as podcasts, calls or interviews and want transcripts inside your assistant without building your own pipeline. Also handy for a quick free check of whether links are readable before paying for transcription.
Requirements
Runs locally as an npm package via npx, needing Node.js 18 or newer. Requires an Apify account and an Apify API token set as APIFY_TOKEN. Transcription needs your own provider API key (Deepgram, AssemblyAI, Groq or OpenAI) passed with the call; OpenAI accepts files up to 25 MB. Network access to Apify and the provider is required.
Before you install
Your provider API key is passed as a tool argument and stored encrypted by Apify, then sent to that provider; treat it as a billable secret. Costs are real: you pay the provider directly plus Apify per media minute and per run start, and max_charge_usd limits only the actor's charge, not your provider bill. Diarization may be billed as an add-on. Media files are sent to third-party services.

README

Media URL Transcriber MCP Server

[npm version] [license]

An MCP server for the Mamba Labs Media URL Transcriber actor on Apify. Turn media file links into transcripts on your own provider key.

What's Inside

What it does

Give direct audio or video file links and your own Deepgram, AssemblyAI, Groq, or OpenAI key. The actor sends each file to that provider and returns one row per file with the transcript, timestamped segments, language, and duration. You pay your provider directly and pay this actor per media minute. It does not download from platforms such as YouTube or TikTok.

All of the work runs on Apify. This package is a thin client that starts the actor run, waits for it, and hands back the dataset rows.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config (claude_desktop_config.json), Cursor, or any MCP client:

json
{  "mcpServers": {    "mamba-media-url-transcriber": {      "command": "npx",      "args": [        "-y",        "@mambalabsdev/mcp-media-url-transcriber"      ],      "env": {        "APIFY_TOKEN": "your-apify-token"      }    }  }}

Restart the client. The transcribe_media_urls tool appears.

Prerequisites

Example prompts

  • "Transcribe this podcast episode file on my Deepgram key."
  • "Turn these 10 recorded call files into text with speaker labels."
  • "Check whether these media links can be read before I transcribe them."

Tool

transcribe_media_urls. One tool. Example arguments:

json
{  "media_urls": [    "https://dpgr.am/spacewalk.wav"  ],  "provider": "deepgram"}

Inputs

Every buyer facing input of the actor. Omitted inputs take the actor's own defaults.

InputTypeRequiredDescription
media_urlsarraynoDirect links to audio or video files (mp3, wav, m4a, mp4, and others) that answer without a login. Platform pages such as YouTube, TikTok, Instagram, Vimeo, or Spotify are refused with a free row. In Clay, put the column inside a one item list.
providerstringnoWhose API transcribes the file, on your key: deepgram (default), assemblyai, groq, or openai. openai takes files up to 25 MB; the others read the URL.
api_keystringnoYour own key for the provider above. It is stored encrypted by Apify, sent only to that provider, and never written to a row or a log. With no key the run checks up to 3 files and transcribes nothing, for free.
modelstringnoOptional. The provider's model name. Defaults: deepgram nova-3, assemblyai its own default, groq whisper-large-v3-turbo, openai whisper-1 (the only one accepted there).
languagestringnoOptional. A language code such as en or de. Empty lets deepgram and assemblyai detect it; whisper models detect it on their own.
diarizebooleannoyes or no (default no). Labels who spoke each segment. deepgram and assemblyai only; your provider may bill it as an add on.
include_segmentsbooleannoyes (default) or no. Adds a list of segments with start and end seconds to each row.
max_charge_usdstringnoOptional. No new file starts once this is used up. A transcript your provider already billed is still delivered, charged up to this amount, and the run then stops. It limits this actor's charge, not your provider's bill.
