Overview

AI-generated overview

Apify-hosted MCP server that transcribes audio and video files and podcast feeds with Whisper, returning text, timestamps and SRT subtitles.

What you can do
  • Transcribe audio and video files and podcast feeds into speech-to-text output
  • Return plain text, timestamps and SRT subtitle files
  • Run Whisper-based transcription through an Apify actor, paid per audio minute
  • No individual tools are listed in the manifest; the README describes the underlying Apify actor and its pay-per-use API
When to use it
Useful when an assistant needs transcripts or subtitles from recordings, interviews, videos or podcast episodes without running a speech model locally.
Requirements
Remote streamable HTTP endpoint at mcp.apify.com. Requires an Apify account and an Apify API token sent as an Authorization header in the form Bearer token; OAuth is declared as required. Network access to Apify.
Before you install
Paid per use, from about $0.003 per audio minute, so costs grow with audio length. The Apify API token is a secret sent in the Authorization header. Audio and video content is uploaded to Apify's hosted service for processing.

Installation

In SourceWeft

  1. Open Audio & Video Transcriber (Whisper) in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.prometheus-maker%2Faudio-video-transcriber/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Apify tools: PDF to Markdown, OCR, Website to Markdown crawler, SEO audit, Tech Stack

Working examples for my pay-per-use tools on the Apify Store. Each one is an API: send URLs, get JSON back. You only pay for what you process, and there's no subscription.

Quick start (curl)

Get an API token from Apify Console → Integrations, then:

bash
curl -X POST "https://api.apify.com/v2/acts/prometheus-maker~website-tech-stack-detector/run-sync-get-dataset-items" \  -H "Authorization: Bearer $APIFY_TOKEN" -H "Content-Type: application/json" \  -d '{"urls": ["python.org"]}'

The same endpoint works for the other tools: replace the tool name and the input.

Use them from Claude, Cursor or any MCP client

Every tool is also an MCP server, hosted by Apify (streamable HTTP). Add one to your client with your Apify token:

json
{  "mcpServers": {    "pdf-to-markdown": {      "url": "https://mcp.apify.com/?tools=prometheus-maker/pdf-document-to-markdown",      "headers": { "Authorization": "Bearer YOUR_APIFY_TOKEN" }    }  }}

Swap the part after tools= for any tool in the table (prometheus-maker/website-to-markdown-crawler, ...), or list several separated by commas. The same entries are in the official MCP Registry under io.github.prometheus-maker/* (files in mcp/). You pay per use, as with the API.

Python

bash
pip install apify-clientexport APIFY_TOKEN=...python python/pdf_to_markdown.py      # PDF → Markdown + RAG chunkspython python/image_to_text_ocr.py    # image → textpython python/tech_stack.py           # domains → technologiespython python/website_to_markdown.py  # website → Markdown pages + chunkspython python/seo_audit.py            # website → SEO scores, issues, broken links

The scripts are in python/. They use apify-client 3.x.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
