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 "X-API-Key" 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 233 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=X-API-Key&grenze=200"
The command carries exactly the condition of this page. 233 entries at 200 each are 2 requests; 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.
Questions about this selection
How do I set up one of these servers in my client?
Open the entry and choose “Build configuration” when a launch template is available. The builder lists the supported clients and identifies the values you need to supply. A generated file does not establish that the server is reachable or works with your installation.
Are the listed servers free?
Membership of this category says nothing about price. Neither a repository address nor the absence of declared required secrets establishes that a service is free. Check the individual provider’s pricing and access terms.
How can I follow changes to this selection?
Each entry identifies the source and collection date of its declarations. The change stream for this category shows published changes to its entries. You can subscribe to its Atom feed without creating an account.
