MCP servers over stdio only

MCP servers whose manifest declares stdio as its only transport. They run as a local process and communicate over standard input and output.

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

• Transports (raw) is the complete, sorted enumeration of what a manifest declares. So "stdio" means exactly that and nothing else: an entry that also declares something different is not in this excerpt.
• This excerpt shares 10,121 of its 10,127 entries with "MCP servers available as a package only" (10,938). Both are measured from different raw declarations; 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.
