Trust breakdown (7 categories)

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. How we score → Why this is hard to score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-knmi). View diagnostics → Pass
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 2 days ago).Pass
  • Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability62
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 789 tokens (~263/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

    No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools · 3 exposed · ~737 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
knmi_dataset_files ~281

List the files in one KNMI Data Platform dataset, newest first by default. Returns filename, size in bytes, creation and last-modified timestamps, plus a page token. This is how you find the most recent radar composite, observation file or model run before downloading it. Get dataset and version from knmi_datasets, e.g. dataset "10-minute-in-situ-meteorological-observations" version "1.0", or dataset "radar_reflectivity_composites" version "2.0".

NameTypeReqDescription
beginstring–Only with order_by "filename": start listing alphabetically after this filename.
datasetstringyesKNMI dataset name, e.g. "10-minute-in-situ-meteorological-observations". Case-sensitive.
max_keysnumber–Files per page (default 10, max 100).
order_bystring–Sort field: "created" (default here), "lastModified" or "filename".
page_tokenstring–nextPageToken from a previous call, to fetch the following page.
sortingstring–"desc" for newest first (default here) or "asc".
versionstringyesDataset version string, e.g. "1.0", "2.0", "1", "5".

knmi_datasets ~242

The KNMI Data Platform datasets worth calling, with what each one contains, how often it updates and its file format — and, checked live, the timestamp of its newest file. AUTHORITATIVE starting point for Dutch weather and climate data: KNMI is the Netherlands national weather service. Use this to find the exact dataset name and version string that knmi_dataset_files needs, because those names are opaque (e.g. "Tg1", "EV24", "harmonie_arome_cy43_p1") and the Open Data API has no listing endpoint of its own. Search for "radar", "observations", "forecast", "precipitation", "temperature", "evaporation".

NameTypeReqDescription
limitnumber–Max datasets to return (default 5, max 11). Each one costs an upstream call when verify is true.
searchstring–Case-insensitive substring matched against dataset name and description, e.g. "radar".
verifyboolean–Check each matched dataset live and report its newest file and timestamp (default true). Set false to skip the upstream calls and just read the registry.

No output schema declared.

No examples provided.

knmi_file_url ~214

Mint a temporary download URL for one file in a KNMI Data Platform dataset. Returns the signed URL, the content type, the byte size and when the file was last modified. The URL is short-lived and must be used promptly. Pass a filename from knmi_dataset_files, e.g. dataset "radar_reflectivity_composites" version "2.0" filename "RAD_NL25_PCP_NA_202609172205.h5". Note the files are scientific binaries (NetCDF, HDF5, GRIB in tar) — this hands back a link to fetch, it does not decode them.

NameTypeReqDescription
datasetstringyesKNMI dataset name, e.g. "radar_reflectivity_composites".
filenamestringyesExact filename from knmi_dataset_files, e.g. "RAD_NL25_PCP_NA_202609172205.h5".
versionstringyesDataset version string, e.g. "2.0".

Is the Knmi MCP server safe to use?

Knmi 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 Knmi MCP server expose?

Knmi exposes 3 tools: knmi_datasets, knmi_dataset_files, knmi_file_url. Their descriptions and schemas cost roughly 737 tokens of context every time the server is loaded.

Is the Knmi MCP server still maintained?

Knmi 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.
