Official ElevenLabs Model Context Protocol (MCP) server for interaction with Text to Speech and audio processing APIs.
The ElevenLabs Model Context Protocol (MCP) server is designed to facilitate seamless interaction with advanced Text to Speech and audio processing APIs. It supports various MCP clients such as Claude Desktop, Cursor, Windsurf, and OpenAI Agents, enabling them to generate speech, clone voices, transcribe audio, and more. The server is equipped with tools that allow users to create AI agents with specific voice characteristics, generate voice variations, convert recordings, and create soundscapes. The server is accessible through a free tier offering 10k credits per month, making it an attractive option for developers and enthusiasts in the field of AI-driven audio processing.
Features
- Text to Speech generation
- Voice cloning and variation
- Audio transcription
- Soundscape creation
- Integration with multiple MCP clients
Tools
text_to_speech
Convert text to speech with a given voice and save the output audio file to a given directory. Directory is optional, if not provided, the output file will be saved to $HOME/Desktop. Only one of voice_id or voice_name can be provided. If none are provided, the default voice will be used.
⚠️ COST WARNING: This tool makes an API call to ElevenLabs which may incur costs. Only use when explicitly requested by the user. Args: text (str): The text to convert to speech. voice_name (str, optional): The name of the voice to use. stability (float, optional): Stability of the generated audio. Determines how stable the voice is and the randomness between each generation. Lower values introduce broader emotional range for the voice. Higher values can result in a monotonous voice with limited emotion. Range is 0 to 1. similarity_boost (float, optional): Similarity boost of the generated audio. Determines how closely the AI should adhere to the original voice when attempting to replicate it. Range is 0 to 1. style (float, optional): Style of the generated audio. Determines the style exaggeration of the voice. This setting attempts to amplify the style of the original speaker. It does consume additional computational resources and might increase latency if set to anything other than 0. Range is 0 to 1. use_speaker_boost (bool, optional): Use speaker boost of the generated audio. This setting boosts the similarity to the original speaker. Using this setting requires a slightly higher computational load, which in turn increases latency. speed (float, optional): Speed of the generated audio. Controls the speed of the generated speech. Values range from 0.7 to 1.2, with 1.0 being the default speed. Lower values create slower, more deliberate speech while higher values produce faster-paced speech. Extreme values can impact the quality of the generated speech. Range is 0.7 to 1.2. output_directory (str, optional): Directory where files should be saved. Defaults to $HOME/Desktop if not provided. language: ISO 639-1 language code for the voice. output_format (str, optional): Output format of the generated audio. Formatted as codec_sample_rate_bitrate. So an mp3 with 22.05kHz sample rate at 32kbs is represented as mp3_22050_32. MP3 with 192kbps bitrate requires you to be subscribed to Creator tier or above. PCM with 44.1kHz sample rate requires you to be subscribed to Pro tier or above. Note that the μ-law format (sometimes written mu-law, often approximated as u-law) is commonly used for Twilio audio inputs. Defaults to "mp3_44100_128". Must be one of: mp3_22050_32 mp3_44100_32 mp3_44100_64 mp3_44100_96 mp3_44100_128 mp3_44100_192 pcm_8000 pcm_16000 pcm_22050 pcm_24000 pcm_44100 ulaw_8000 alaw_8000 opus_48000_32 opus_48000_64 opus_48000_96 opus_48000_128 opus_48000_192 Returns: Text content with the path to the output file and name of the voice used.speech_to_text

⚠️ COST WARNING: This tool makes an API call to ElevenLabs which may incur costs. Only use when explicitly requested by the user. Args: file_path: Path to the audio file to transcribe language_code: ISO 639-3 language code for transcription (default: "eng" for English) diarize: Whether to diarize the audio file. If True, which speaker is currently speaking will be annotated in the transcription. save_transcript_to_file: Whether to save the transcript to a file. return_transcript_to_client_directly: Whether to return the transcript to the client directly. output_directory: Directory where files should be saved. Defaults to $HOME/Desktop if not provided. Returns: TextContent containing the transcription. If save_transcript_to_file is True, the transcription will be saved to a file in the output directory.text_to_sound_effects
Convert text description of a sound effect to sound effect with a given duration and save the output audio file to a given directory. Directory is optional, if not provided, the output file will be saved to $HOME/Desktop. Duration must be between 0.5 and 5 seconds.
⚠️ COST WARNING: This tool makes an API call to ElevenLabs which may incur costs. Only use when explicitly requested by the user. Args: text: Text description of the sound effect duration_seconds: Duration of the sound effect in seconds output_directory: Directory where files should be saved. Defaults to $HOME/Desktop if not provided. output_format (str, optional): Output format of the generated audio. Formatted as codec_sample_rate_bitrate. So an mp3 with 22.05kHz sample rate at 32kbs is represented as mp3_22050_32. MP3 with 192kbps bitrate requires you to be subscribed to Creator tier or above.
