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.
• 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.
