MCP servers requiring credentials
MCP servers for which the registry lists at least one environment variable marked secret and required. Raw declaration and source beside it.
What this excerpt selects
| Credentials required | yes derived from: Required secret variables (raw) |
|---|
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
- Credentials required is not declared but computed: from Required secret variables (raw), Required secret headers (raw). The rule is published, with a version, on the methodology page.
- 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.
