AssemblyAI MCP: transcribe and analyze audio from your AI app

Hook AssemblyAI up to Claude, ChatGPT or Cursor

1. 1Click Connect AssemblyAI free and sign in with your AssemblyAI account.
2. 2Deleting a transcript's content can't be undone, and AssemblyAI offers no way to delete uploaded media through its API. If your AI app only needs to read and search transcripts, switch off delete and upload tools when you see them in the list.
3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
4. 4Give your AI app a link to a recording, ask for a transcript with timestamps, then open Activity to see the submit and fetch calls.

Audio work you can hand to Claude or ChatGPT

• Queue a transcription from a media URL, or upload an audio or video file first.
• Search a finished transcript for a word or phrase and get counts and timestamps.
• Export a completed transcript as SRT or WebVTT subtitles.
• Pull sentence or paragraph segments with timestamps and confidence, or list the last 90 days of transcripts.
• Fetch PII-redacted audio for a transcript submitted with redaction.

Guard your recordings and transcripts

• Switch off transcript deletion so a stray request can't wipe stored content; the tool is hidden and refused if called.
• Policies check every call, for example hiding personal data or warning before a transcript is deleted.
• Activity keeps a record of every transcription, search and export.
