    Description, as the server wrote it
    Current flood situation: stations with an active LHP flood class (1 small … 4 very large), optionally per federal state. Every result names the data provider in sourceNotice (search and flood situation: sourceNotices, keyed by sourceNoticeId); show that notice with any value, class or forecast you pass on, and the licence terms of the API require it.

    Description, as the server wrote it
    Newest published water-level forecast for a station: the median of the state agency model run, future points within the horizon. Only gauges whose state publishes numeric forecasts have one, so an empty result is normal. Indicative, not an official warning.

    Description, as the server wrote it
    Time series for a station (downsampled to ≤200 points; history depth on this tier: last 90 days, default last 7 days). type "level" (default) → level series as stored valueCentimeters: centimetres above gauge zero for most gauges, but an elevation ×100 for groundwater wells and for gauges reporting an absolute elevation (Swiss gauges, the Neusiedler See) — divide by valueDivisor to read it in unit. type "discharge" → discharge Q in m³/s where the station provides it.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write6
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__pegel__search_stations",
      "mcp__pegel__get_flood_situation",
      "mcp__pegel__get_station",
      "mcp__pegel__get_readings",

      "mcp__pegel__get_forecast"
    ],
    "ask": [],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as pegel. Review it before you use it.
