Nothing serious here today

Today is the operative word: we check River Level MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 4

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

river

find_river_gauges

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_history

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_river_level

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.

flood

get_flood_forecast

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.

River Level MCP — questions

Answers built from our own checks of this server.

What can River Level MCP do?

It exposes 4 tools, read directly from the server on our last check. Among them: find_river_gauges, get_flood_forecast, get_river_history, get_river_level. 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 River Level MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 23 of 23 checks got a reply (100.0%), average response time 182 ms. The bar chart above shows every period we have measured.

How do I connect River Level MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does River Level MCP need an API key?

No. River Level MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is River Level MCP?

It answers our handshake in 182 ms on average, which is faster than 78% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is River Level MCP open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at river-level-mcp.lipmichal.workers.dev, which runs on its operator's own terms.
