Supported Tools

list_transcripts

List Transcripts

List transcripts with pagination and optional filters. Returns transcript summaries sorted from newest to oldest. Supports filtering by status and creation date, and cursor-based pagination using before/after IDs.

get_transcript_text

Get Transcript Text

Retrieve a completed transcript's text segmented into sentences or paragraphs. The API semantically segments the text for more reader-friendly output. Choose "sentences" or "paragraphs" segmentation depending on how granular you need the output.

get_subtitles

Get Subtitles

Export a completed transcript as SRT or VTT subtitle format for use with video players for subtitles and closed captions. Optionally limit the number of characters per caption line.

search_transcript

Search Transcript

Search through a completed transcript for specific keywords. You can search for individual words, numbers, or phrases of up to five words. Returns match counts and timestamps for each keyword found.

delete_transcript

Delete Transcript

Delete a transcript by removing its data and marking it as deleted. The transcript resource itself remains but its data is permanently removed. Any files uploaded via the upload endpoint are also immediately deleted alongside the transcript.

submit_transcription

Submit Transcription

Submit an audio or video file for asynchronous transcription. Provide a publicly accessible URL to the media file. Optionally enable audio intelligence features like summarization, sentiment analysis, entity detection, topic detection, content moderation, key phrases, auto chapters, and PII redaction. Returns the transcript object with a status of "queued" — poll using the **Get Transcript** tool to check for completion.

get_transcript

Get Transcript

Retrieve a transcript by its ID. Returns the full transcript object including text, words with timestamps, speaker labels, and any enabled audio intelligence results (summary, sentiment, entities, topics, chapters, content safety, key phrases). Use this to poll for completion after submitting a transcription, or to retrieve results of a completed transcript.

create_streaming_token

Create Streaming Token

Generate a temporary authentication token for use with AssemblyAI's real-time streaming speech-to-text WebSocket API. Use this to securely authenticate client-side streaming without exposing your main API key. Each token is single-use and valid for one streaming session.

lemur_task

LeMUR Task

Apply a large language model to one or more transcripts using AssemblyAI's LeMUR framework. Submit a custom prompt along with transcript IDs or raw text input, and receive an LLM-generated response. Use this for summarizing transcripts, extracting insights, answering questions about audio content, generating action items, or any custom analysis task. Supports multiple LLM providers including Claude, GPT, and Gemini models.

get_redacted_audio

Get Redacted Audio

Retrieve the URL for a PII-redacted audio file. The original transcription must have been submitted with PII audio redaction enabled (`redactPiiAudio: true`). The redacted audio has personally identifiable information "beeped" out.

Connect Assemblyai to your AI client

Every client uses the same Magic MCP URL, and so does any other MCP client. Add it once and sign in with SSO.

  1. Enable Assemblyai in Metorial. In your Metorial portal, enable the Assemblyai MCP server and sign in with the account that owns the data. Access stays governed by your team policies.
  2. Add a custom connector. Open Customize, then Connectors. Select Add, then Custom, then Web.
  3. Paste your Metorial MCP URL. Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>) and continue.
  4. Sign in. Select Add and sign in to load Assemblyai tools.

Run Assemblyai through the Metorial gateway

One governed layer for every app your agents reach, not a separate connector per tool.

  • Give Assemblyai and every other app to your whole team through one MCP gateway, behind your SSO.
  • Scope which teams and agents can use Assemblyai tools with role-based access control, and trace every call.
  • Prefer to run it yourself? Metorial is open source and self-hostable.
