Required secrets declaredno
derived from: Required secret variables (raw)

A derived value carries its original data beside it; the derivation rule is published, with a version, on the methodology page.

Caveats, distribution and query

What this category does not say

  • Required secrets declared is not declared but computed: from Required secret variables (raw), Required secret headers (raw). The rule is published, with a version, on the methodology page.

What is measured is what a manifest declares, not what a piece of software does. This registry fetches no repository URL, no endpoint and no package index; nothing here is verified. Which value comes from which source, and by which rule it was formed, is set out in the Methodology.

Every sentence here follows from the condition above, not from an assessment.

Per property, the measured values inside this category. The share refers to the 35,800 entries of the category, not to the registry. Shown are 6 of 7 properties: those whose values spread the most inside this category.

The same category through the interface

curl -s "https://api.tracevero.com/v1/eintraege?art=mcp_server&zugangsdaten_erforderlich=false&grenze=200"

The command carries exactly the condition of this page. 35,800 entries at 200 each are 179 requests; the total is in the X-Gesamt header.
