Overview

DWD — German weather: DWD ICON forecasts, current conditions, official warnings & pollen's local MCP server; no sign-in required; STDIO.

No AI overview yet: these facts come from the registry entry and the server itself.

Installation

In SourceWeft

  1. Open DWD — German weather: DWD ICON forecasts, current conditions, official warnings & pollen in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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):

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

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

Tools

ToolDescription
dwd_forecastICON-model forecast (hourly + daily) — place (e.g. "Berlin"), days 1..7
dwd_current_weatherCurrent conditions — place (e.g. "München")
dwd_warningsOfficial DWD warnings — state (e.g. "Bayern" or "BY"), min_level 1..4
dwd_pollenPollen counts by type — place (e.g. "Berlin"), days 1..7
dwd_find_placeGeocode German places — query (e.g. "München")
dwd_healthReachability 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).

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
