Implementation Reference

• elevenlabs_mcp/server.py:451-465 (handler)

  The main handler function for the 'voice_clone' tool. It processes input files, calls the ElevenLabs API to create an instant voice clone (IVC), and returns success information including the new voice ID.

  def voice_clone(
      name: str, files: list[str], description: str | None = None
  ) -> TextContent:
      input_files = [str(handle_input_file(file).absolute()) for file in files]
      voice = client.voices.ivc.create(
          name=name, description=description, files=input_files
      )
  
      return TextContent(
          type="text",
          text=f"""Voice cloned successfully: Name: {voice.name}
          ID: {voice.voice_id}
          Category: {voice.category}
          Description: {voice.description or "N/A"}""",
      )

• elevenlabs_mcp/server.py:445-450 (registration)

  The @mcp.tool decorator registers the 'voice_clone' function as an MCP tool, including its description and parameters (name: str, files: list[str], description: str | None).

  @mcp.tool(
      description="""Create an instant voice clone of a voice using provided audio files.
