Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (3)

get_flood_statusGet current flood conditions for USGS monitoring sites in a state. Returns sites where water levels are above flood stage, indicating active flooding or near-flood conditions. Checks the most recent instantaneous values against known flood stages. Args: state: Two-letter US state abbreviation (e.g. 'CA', 'TX', 'LA').
get_sites_by_stateFind USGS water monitoring sites in a state. Returns a list of monitoring stations with their site numbers, names, and locations. Use site numbers with get_water_levels to retrieve data. Args: state: Two-letter US state abbreviation (e.g. 'CA', 'TX'). site_type: Type of monitoring site. 'ST' for stream/river, 'GW' for groundwater well, 'SP' for spring. limit: Maximum number of sites to return (default 50).
get_water_levelsGet recent water level and streamflow data for a USGS monitoring site. Returns time-series data including discharge (streamflow) and gage height for the specified monitoring station. Args: site_number: USGS site number (e.g. '01646500' for Potomac River at Little Falls). days: Number of days of data to retrieve (default 7, max 120).
