Required secret headers (raw)Authorization
measured directly

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 secret headers (raw) is the complete, sorted enumeration of what a manifest declares. So "Authorization" means exactly that and nothing else: an entry that also declares something different is not in this category.

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 2,131 entries of the category, not to the registry.

The same category through the interface

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

The command carries exactly the condition of this page. 2,131 entries at 200 each are 11 requests; the total is in the X-Gesamt header.

Changes to these entries

https://tracevero.com/aenderungen.atom?thema=kopfzeile-authorization

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.
