MCP servers over stdio only

What this category 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 category.
• This category shares 13,764 of its 13,770 entries with "MCP servers available as a package only" (14,812). Both are measured from different original data; 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.

How this category is distributed

Per property, the measured values inside this category. The share refers to the 13,770 entries of the category, not to the registry.

Both addresses narrow the change stream to exactly the entries in this category. The feed carries an identifier of its own, so a feed reader keeps it apart from the full stream.
