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
| Transports (raw) | stdio measured directly |
|---|
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 10,035 of its 10,041 entries with "MCP servers available as a package only" (10,841). Both are measured from different raw declarations; that they hit almost the same set is a finding, not a rule.
- 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.

Per property, the measured values inside this excerpt. The share refers to the 10,041 entries of the excerpt, not to the registry.
The same excerpt through the interface
curl -s "https://api.tracevero.com/v1/eintraege?art=mcp_server&roh_transportarten=stdio&grenze=200"
The command carries exactly the condition of this page. 10,041 entries at 200 each are 51 requests; the total is in the X-Gesamt header.
Changes to these entries
https://tracevero.com/aenderungen.atom?thema=transport-stdio
Both addresses narrow the change stream to exactly the entries in this excerpt. The feed carries an identifier of its own, so a feed reader keeps it apart from the full stream.
Excerpts sharing entries with this one
Per neighbour its own size and the counted number of shared entries. An excerpt without a single shared entry is not listed here.
