Implementation Reference

• elevenlabs_mcp/server.py:757-768 (registration)

  The @mcp.tool decorator registers the 'list_conversations' tool and provides the schema via parameter descriptions in the docstring.
  @mcp.tool( description="""Lists agent conversations. Returns: conversation list with metadata. Use when: asked about conversation history. Args: agent_id (str, optional): Filter conversations by specific agent ID cursor (str, optional): Pagination cursor for retrieving next page of results call_start_before_unix (int, optional): Filter conversations that started before this Unix timestamp call_start_after_unix (int, optional): Filter conversations that started after this Unix timestamp page_size (int, optional): Number of conversations to return per page (1-100, defaults to 30) max_length (int, optional): Maximum character length of the response text (defaults to 10000) """ )
• elevenlabs_mcp/server.py:769-829 (handler)

  The core handler function that executes the tool: fetches conversations from ElevenLabs API, formats them with metadata, handles pagination, truncates large responses if needed, and returns formatted TextContent.
