ElevenLabs Automation

Automate your ElevenLabs text-to-speech workflows -- convert text to natural speech, browse the voice library, inspect voice details, check subscription credits, select TTS models, stream audio for low-latency delivery, and retrieve previously generated audio from history.

Toolkit docs: composio.dev/toolkits/elevenlabs

Setup

  • Add the Composio MCP server to your client: https://rube.app/mcp

  • Connect your ElevenLabs account when prompted (API key authentication)

  • Start using the workflows below

    • Core Workflows

    1. Generate Speech from Text

    Use ELEVENLABS_TEXT_TO_SPEECH to convert text into a downloadable audio file.

    Tool: ELEVENLABS_TEXT_TO_SPEECH
Inputs:
  - voice_id: string (required) -- obtain from ELEVENLABS_GET_VOICES
  - text: string (required) -- max ~10,000 chars (most models), 30,000 (Flash/Turbo v2), 40,000 (v2.5)
  - model_id: string (default "eleven_monolingual_v1") -- e.g., "eleven_multilingual_v2"
  - output_format: string (default "mp3_44100_128") -- see formats below
  - optimize_streaming_latency: integer (0-4; NOT supported with eleven_v3)
  - seed: integer (optional, for reproducibility -- not guaranteed)
  - pronunciation_dictionary_locators: array (optional, up to 3 dictionaries)

    Output formats:

  • MP3: mp3_22050_32, mp3_44100_32, mp3_44100_64, mp3_44100_96, mp3_44100_128, mp3_44100_192 (Creator+)

  • PCM: pcm_16000, pcm_22050, pcm_24000, pcm_44100 (Pro+)

  • uLaw: ulaw_8000 (for Twilio)

    • Important: Output is a file object with a presigned download link at data.file.s3url (expires in ~1 hour). Download promptly.

    2. Browse Available Voices

    Use ELEVENLABS_GET_VOICES to list all voices with their attributes and settings.

    Tool: ELEVENLABS_GET_VOICES
Inputs: (none)

    Returns an array at data.voices[] with voice_id, name, labels (gender, accent, use_case), and settings.

    3. Inspect a Specific Voice

    Use ELEVENLABS_GET_VOICE to get detailed metadata for a candidate voice before synthesis.

    Tool: ELEVENLABS_GET_VOICE
Inputs:
  - voice_id: string (required) -- e.g., "21m00Tcm4TlvDq8ikWAM"
  - with_settings: boolean (default false) -- include detailed voice settings

    4. Check Subscription and Credits

    Use ELEVENLABS_GET_USER_SUBSCRIPTION_INFO to verify plan limits and remaining credits before bulk generation.

    Tool: ELEVENLABS_GET_USER_SUBSCRIPTION_INFO
Inputs: (none)

    5. List Available TTS Models

    Use ELEVENLABS_GET_MODELS to discover compatible models and filter by can_do_text_to_speech: true.

    Tool: ELEVENLABS_GET_MODELS
Inputs: (none)

    6. Stream Audio and Retrieve History

    Use ELEVENLABS_TEXT_TO_SPEECH_STREAM for low-latency streamed delivery, and ELEVENLABS_GET_AUDIO_FROM_HISTORY_ITEM to re-download previously generated audio.

    Tool: ELEVENLABS_TEXT_TO_SPEECH_STREAM
  - Same core inputs as TEXT_TO_SPEECH but returns a stream for low-latency playback

Tool: ELEVENLABS_GET_AUDIO_FROM_HISTORY_ITEM
  - history_item_id: string (required) -- ID from a previous generation

    Known Pitfalls

    PitfallDetail
    Text length limitsMost models cap at ~10,000-20,000 chars per request. Oversized input returns HTTP 400. Split long text into chunks (~5000 chars) and generate per chunk.
    Output is a presigned URLELEVENLABS_TEXT_TO_SPEECH returns data.file.s3url with a ~1 hour expiry (X-Amz-Expires=3600). Download the audio file promptly.
    Quota and credit errorsHTTP 401 with quota_exceeded or HTTP 402 payment_required means insufficient credits or tier restrictions. Check with ELEVENLABS_GET_USER_SUBSCRIPTION_INFO before bulk jobs.
    Voice permissionsHTTP 401 with missing_permissions means the API key lacks voices_read scope. Verify key permissions.
    Model compatibilityNot all models support TTS. Use ELEVENLABS_GET_MODELS and filter by can_do_text_to_speech: true. The optimize_streaming_latency parameter is NOT supported with eleven_v3.
    Large voice list truncationELEVENLABS_GET_VOICES may return a large list. Select from the full data.voices[] payload -- previews may appear truncated.
