MCP servers without a declared package registry

What this category does not say

• Package registries (raw) is the complete, sorted enumeration of what a manifest declares. So "nothing declared" means exactly that and nothing else: an entry that also declares something different is not in this category.
• The empty value means "the source explicitly declares nothing here". It does not mean "not recorded": what was never recorded is in no category of this property.
• This category shares 25,222 of its 25,719 entries with "Remotely executed MCP servers" (25,476). Both are measured from different original data; that they hit almost the same set is a finding, not a rule.

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.
