Parameters:
    chain: chain name (e.g., 'ethereum')

    exclude_total_data_chart_breakdown: true to exclude broken down chart from response
    data_type: desired data type (default: 'dailyNotionalVolume')

Implementation Reference

• defillama_server.py:833-856 (handler)

  The handler function for the get_options_overview_by_chain tool, registered via @mcp.tool() decorator. It constructs parameters and makes an API request to DefiLlama's /api/overview/options/{chain} endpoint to retrieve options DEX summaries filtered by chain.

  @mcp.tool()

      chain: str,

      exclude_total_data_chart_breakdown: bool = True,
      data_type: Literal['dailyPremiumVolume', 'dailyNotionalVolume'] = 'dailyNotionalVolume'
