## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-dwd-climate).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 4 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 521 tokens (~173/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 82, +1)

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (3)

### `dwd_stations` (~199 tokens)

Find German Weather Service (DWD) climate stations by name or nearest to a coordinate. Returns station id, name, federal state, elevation, coordinates and the first/last date of daily climate observations, with distance when searching by lat/lon. Use the station_id with dwd_daily or dwd_latest. Covers ~1,400 current and closed stations across Germany. Source: Deutscher Wetterdienst.

Input parameters:

- `active_only` (boolean): Only stations still reporting (default true)
- `lat` (number): Latitude for a nearest-station search (use with lon)
- `limit` (number): Max stations to return (default 10, max 50)
- `lon` (number): Longitude for a nearest-station search (use with lat)
- `name` (string): Station or place name, substring match, umlauts optional (e.g. "Dresden", "Muenchen", "Zugspitze")

### `dwd_daily` (~189 tokens)

Daily climate observations for one German DWD station over a date range: mean/max/min temperature, precipitation, sunshine hours, snow depth, wind speed and gusts, humidity, pressure and cloud cover, each with DWD quality flags. Ranges older than ~500 days come from the quality-controlled historical archive (back to the station's first record, some to the 1800s); recent days from the daily update. Max 1000 days per call. Get station_id from dwd_stations.

Input parameters:

- `from` (string): Start date YYYY-MM-DD (default: 30 days before "to")
- `station_id` (string, required): DWD station number (e.g. "1048" Dresden-Klotzsche, "433" Berlin-Tempelhof, "3379" München-Stadt)
- `to` (string): End date YYYY-MM-DD (default: today)

### `dwd_latest` (~77 tokens)

Most recent daily climate observation for one German DWD station (usually yesterday): temperature mean/max/min, precipitation, sunshine, snow depth, wind and humidity, with quality flags. Get station_id from dwd_stations.

Input parameters:

- `station_id` (string, required): DWD station number (e.g. "1048" Dresden-Klotzsche)

## Common questions

### What is the Dwd Climate MCP server?

Dwd Climate is an MCP server listed in the public MCP registry as io.github.pipeworx-io/dwd-climate. DWD Climate Data Center, daily station observations for Germany. This page covers its npm package (@pipeworx/mcp-dwd-climate).

### Is the Dwd Climate MCP server safe to use?

Dwd Climate scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Dwd Climate MCP server expose?

Dwd Climate exposes 3 tools: dwd_stations, dwd_daily, dwd_latest. Their descriptions and schemas cost roughly 465 tokens of context every time the server is loaded.

### Is the Dwd Climate MCP server still maintained?

Dwd Climate is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Dwd Climate MCP server under?

Dwd Climate declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Dwd Climate MCP server?

VerifyMCP ran 16 checks on Dwd Climate, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
