Args:
    district: The name of the district within the specified state for which to retrieve flood warning conditions.
    state: The name of the state in Malaysia for which to retrieve flood warning conditions.

Implementation Reference

• weather.py:10-44 (handler)

  The core handler function implementing the tool logic. It processes input district/state, queries the Malaysian government flood-warning API for active (ON) water level statuses, handles errors/no data, formats results using format_water_level helper, and returns joined summaries.

  async def get_water_level_condition(district: str = "", state: str = "") -> str:
      """Retrieve the water level conditions associated with flood warnings for a specified district or state.
      If both district and state are provided, the district takes precedence.
      If district or state is not specified, use an empty string for that field.

• weather.py:9-9 (registration)

  The @mcp.tool() decorator registers the get_water_level_condition function as a tool on the FastMCP server instance.

  @mcp.tool()

• helpers.py:49-74 (helper)

  Supporting helper function that formats the API response data for water level stations into a detailed human-readable string used in the tool output.
