ElevenLabs Automation

ElevenLabs Text-to-Speech Automation Integration

By integrating with Composio MCP, add ElevenLabs text-to-speech capabilities to your AI Agent—enabling automated voice generation, voice library browsing, subscription monitoring, and historical lookup.

Skill Overview

ElevenLabs Automation is an MCP (Model Context Protocol) integration tool that lets developers call ElevenLabs’ text-to-speech API directly from within an AI Agent, without writing additional integration code.

Use Cases

1. Content Creation Automation

Batch-generate voiceovers for podcasts, audiobooks, and video tutorials. Automatically create high-quality voice content from text scripts, helping content creators and media teams improve production efficiency.

2. Multilingual Voice Synthesis

Use ElevenLabs’ multilingual models to automatically generate voice versions in multiple languages for internationalized projects, covering scenarios such as education, customer service, and navigation.

3. Real-Time Voice Interaction Applications

With streaming capabilities, build low-latency voice dialogue systems suitable for applications that require immediate voice feedback, such as intelligent customer support, voice assistants, and real-time translation.

Core Features

Text-to-Speech Generation

Convert text into natural, fluent speech audio. Supports multiple model choices (including Multilingual v2, Turbo v2, Flash, etc.) and output formats (MP3, PCM, uLaw). You can set a seed value for voice reproducibility, and a custom pronunciation dictionary is supported. Up to 40,000 characters per request are supported (v2.5 model).

Voice Library Browsing and Checking

Retrieve a list of all available voices and their metadata (gender, accent, scenario tags). Supports detailed information queries for individual voices, helping developers choose the most suitable voice roles for content creation.

Subscription and Quota Management

Real-time lookup of account subscription details and remaining character quotas to avoid generation failures due to insufficient credits. Ideal for pre-checks and resource planning before batch jobs.

Frequently Asked Questions

How does ElevenLabs Automation integrate into an AI Agent?

Add the Composio MCP server https://rube.app/mcp to your MCP client. On the first call, connect your ElevenLabs account (requires an API Key), and then you can use all ElevenLabs features within your Agent.

What are the limits of text-to-speech requests?

Most models limit requests to about 10,000–20,000 characters per call. Flash/Turbo v2 supports up to 30,000 characters, and the v2.5 model supports up to 40,000 characters. If the limit is exceeded, an HTTP 400 error is returned. It’s recommended to split long text into chunks of around 5,000 characters and generate them separately.

How long are the generated audio files saved?

ELEVENLABS_TEXT_TO_SPEECH returns an S3 pre-signed download link (data.file.s3url) valid for about 1 hour. Download the audio files to local storage promptly to avoid access issues after the link expires.
