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

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.
