River Gauges MCP Connector for Claude

Connect any AI agent to real river gauge readings — the streamflow and gage-height data the USGS measures at thousands of surface-water sites, refreshed as often as every 5 to 15 minutes. No key required.

What you can do

• Ask what the river is doing right now — the latest streamflow and gage height at a site, plus the last few readings so the trend shows, with water temperature, conductance, dissolved oxygen and pH available on request
• Get the recent level curve — the gage-height history over the last hours, by default 24, with the range and whether the river is rising or falling over the window
• Look up a gauge site — name, coordinates, drainage area, altitude and site type, which is what puts a flow number in context
• List gauges by state — every USGS surface-water site in a state, to find the id you need

How it works

1. Subscribe to this server — no account, no key
2. Ask your agent: "How high is the Potomac at Little Falls right now?", "Is the river rising at site 01646500?", "List the gauges in Maryland"
3. The agent reads the live gauge and answers in plain language

Good to know

Streamflow is the volume of water moving past the gauge — cubic feet per second in the US. Gage height is the water level against the gauge staff, not an altitude above sea level, so it is only meaningful against that site's own history. Recent readings are marked provisional: USGS checks and revises them, so a number from the last day or two can change. Coverage is the United States.

Who is this for

• Paddlers, anglers and boaters — "is my run in?" answered by the gauge that sits on it
• Flood watchers and emergency managers — a rising curve under heavy rain is the flood signature
• Water utilities and irrigators — real flow at the intake, not yesterday's report
• Anyone with a chat window — "is the river up?" answered from measurements, not a guess
