Caveats, distribution and query

What this category does not say

  • Field of use, derived from the vendor description is not declared but computed: from Description (raw). The rule is published, with a version, on the methodology page.
  • 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 192 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&einsatzgebiet=epost&zugangsdaten_erforderlich=true&grenze=200"

The command carries exactly the condition of this page. 192 entries at 200 each are a single request; the total is in the X-Gesamt header.

Changes to these entries

Both addresses narrow the change stream to exactly the entries in this category. The feed carries an identifier of its own, so a feed reader keeps it apart from the full stream.
