dwd-mcp 🌤️

mcp-name: io.github.mohammad-abbasi-sh/dwd-mcp

Unofficial read-only MCP server for DWD (Deutscher Wetterdienst) — German weather from the Deutscher Wetterdienst (DWD): ICON-model forecasts and current conditions via Open-Meteo, official DWD severe-weather warnings, and pollen counts. No key, no login.

Built by Mohammad Abbasi as part of the "Germany MCP factory". Not affiliated with DWD (Deutscher Wetterdienst).

For AI agents

Add to your MCP client config (stdio):

{
  "mcpServers": {
    "dwd": {
      "command": "uvx",
      "args": ["dwd-mcp==0.1.0"]
    }
  }
}

Or run locally: python -m dwd_mcp.server (needs mcp<2, httpx).

Tools

Tool	Description
dwd_forecast	ICON-model forecast (hourly + daily) — place (e.g. "Berlin"), days 1..7
dwd_current_weather	Current conditions — place (e.g. "München")
dwd_warnings	Official DWD warnings — state (e.g. "Bayern" or "BY"), min_level 1..4
dwd_pollen	Pollen counts by type — place (e.g. "Berlin"), days 1..7
dwd_find_place	Geocode German places — query (e.g. "München")
dwd_health	Reachability probe (ok / blocked / error) — one polite request

Notes

• Forecasts and current conditions come from the DWD ICON model via Open-Meteo (api.open-meteo.com) — the DWD's own numerical model, free, no key.
• dwd_warnings reads the official DWD warnapp feed (www.dwd.de/DWD/warnungen/warnapp/json/warnings.json) — a warnWetter.loadWarnings({...}); JSONP wrapper, stripped here. Warnings are sorted by level (highest first).
• dwd_pollen is CAMS pollen data via the Open-Meteo air-quality API, not DWD data — the tool output says so. DWD publishes no public pollen JSON (verified 2026-11-10: the warnapp pollen path is a 404).
• Daily station observations (CDC) are intentionally out of scope — pipeworx-io/mcp-dwd-climate already covers them in the official registry.

Tests: 22/22 green (15 offline + 7 live, 2026-11-10).
