What is the AssemblyAI MCP Server?

Empower your AI agent to orchestrate your entire audio intelligence and transcription workflow with AssemblyAI, the leading platform for speech-to-text. By connecting AssemblyAI to your agent, you transform complex audio processing into a natural conversation. Your agent can instantly start transcription jobs from any URL, audit transcript results with high confidence, and manage job history without you ever touching a technical console. Whether you are analyzing podcast content or transcribing meetings, your agent acts as a real-time linguistic assistant, ensuring your audio data is always accessible and searchable.

What you can do

  • Transcription Auditing — Start transcription jobs for any audio or video URL and retrieve cleaned text with speaker labels.
  • Linguistic Oversight — Retrieve transcripts broken down by sentences or paragraphs to maintain a structured view of spoken content.
  • Status Intelligence — Monitor the progress of long-running transcription jobs to ensure timely data delivery.
  • Execution Management — List all past and active transcripts to maintain strict organizational control over your audio assets.
  • Confidence Intelligence — Retrieve confidence scores for each transcription to verify the accuracy of your linguistic data.
