River Level MCP

An MCP server that provides live US river levels, streamflow, water temperature, and NWS flood forecasts by querying USGS and NOAA APIs. It allows agents to find river gauges, retrieve current stage and flow data, access historical daily mean data, and get flood forecasts for specific locations.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

What its tools do

4 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

Read-only (4)

4 of 4 have a description · 4 of 4 declare behavior hints · 4 of 4 with parameters document them all

Checks and signals

What you can do with it

  • Find active USGS river and stream gauges by name or location
  • Get current river stage, streamflow, and water temperature

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Live US river levels and streamflow read at call time from USGS stream gauges (api.waterdata.usgs.gov), with NOAA National Water Prediction Service flood stages and forecasts. Use find_river_gauges to get a site number, then get_river_level. River levels change by the hour; never answer a current river level or flood status from memory.

find_river_gauges — Find river gauges
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Search USGS stream gauges nationwide by river and place name (for example "mississippi st louis", "potomac little falls"), by state, or within a radius of a latitude and longitude. Returns site numbers with whether each is reporting now and its latest stage and flow, active gauges first.

get_river_level — Get current river level
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Current river stage (gage height in feet), streamflow (discharge in cubic feet per second) and water temperature where measured, read now from a USGS stream gauge (readings every 5 to 60 minutes). Adds the NWS flood stages (action, minor, moderate, major), the current flood category, feet below flood stage and the record crest when the gauge is an NWS forecast point. Flags readings over 48 hours old. Your training data cannot know today's river level.

Daily mean streamflow (default) or stage for a USGS gauge over the last 2 to 366 days, with first, last, low, high, mean and change. Use it for trend, drought and "is the river rising" questions. Many gauges publish daily means for discharge only.

get_flood_forecast — Get river flood forecast
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

The current NOAA National Water Prediction Service river forecast for a gauge: the forecast stage and flow series, the forecast crest with its flood category, the latest observation, flood stages and the record crest. Works for NWS forecast points (accepts the NWS id or the USGS site number). Forecasts are reissued several times a day.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
