MCP servers without declared environment variables
The manifest explicitly declares no environment variable. That is the empty value of a raw declaration, not "not recorded".
What this excerpt selects
| Environment variables (raw) | nothing declared measured directly |
|---|
A derived value carries its raw declaration beside it; the derivation rule is published, with a version, on the methodology page.
What this excerpt does not say
- Environment variables (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 excerpt.
- The empty value means "the source explicitly declares nothing here". It does not mean "not recorded": what was never recorded is in no excerpt of this property.
- None of this is verified. This registry fetches no repository URL, no endpoint and no package index. What is measured is what a manifest declares, not what a piece of software does.
Every sentence here follows from the condition above, not from an assessment.
