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.

live
get_live_gauges
Today's official water-level readings (cm) at the cruise-critical gauges on the Rhine, Danube, Elbe and Seine, with each station's state and its percentile against thirty years.
month
get_month_detail
Why a given month behaves the way it does on one of the four rivers: the seasonal hydrology, the thirty-year frequency, and the last five years' outcomes for that month.
monthly
get_monthly_odds
Current 12-month cruise-disruption odds for one of Europe's main cruise rivers (chance a sailing day hits low water, or high water on the Seine). Refreshed daily from official sources.
score
score_sailing
Score a specific river cruise: the chance a sailing departing on a given date meets low water (high water on the Seine) at its river's tightest stretch. Uses the live daily forecast where it reaches (~7 months) and the thirty-year weekly record beyond, plus what the same dates actually did in each of the last five years.

River Water Watch — questions

Answers built from our own checks of this server.

What can River Water Watch do?
It exposes 4 tools, read directly from the server on our last check. Among them: get_live_gauges, get_month_detail, get_monthly_odds, score_sailing. 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 Water Watch working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 10 of 91 checks got a reply (11.0%), average response time 368 ms. The bar chart above shows every period we have measured.
Is River Water Watch still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
The registry lists River Water Watch as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect River Water Watch?
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 Water Watch need an API key?
No. River Water Watch 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 Water Watch?
It answers our handshake in 368 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
