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.

Per property, the measured values inside this excerpt. The share refers to the 18,424 entries of the excerpt, not to the registry. Shown are 6 of 8 properties: those whose values spread the most inside this excerpt.
The same excerpt through the interface
curl -s "https://tracevero.com/api/v1/eintraege?art=mcp_server&roh_umgebungsvariablen=&grenze=200"
The command carries exactly the condition of this page. 18,424 entries at 200 each are 93 requests; the total is in the X-Gesamt header.
Changes to these entries
