Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

flood
get_flood_status
Get 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').
sites
get_sites_by_state
Find 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).
water
get_water_levels
Get 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).

USGS Water Monitoring — questions

Answers built from our own checks of this server.

What can USGS Water Monitoring do?
It exposes 3 tools, read directly from the server on our last check. Among them: get_flood_status, get_sites_by_state, get_water_levels. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is USGS Water Monitoring working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 535 ms. The bar chart above shows every period we have measured.
How do I connect USGS Water Monitoring?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does USGS Water Monitoring need an API key?
No. USGS Water Monitoring completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is USGS Water Monitoring?
It answers our handshake in 535 ms on average, which is faster than 20% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
