MCP-DSC-003

Advertised versions include a currently-supported revision

This rule's verbatim spec quote hasn't been captured yet — see validator/README.md. It is not yet counted toward coverage or graded.

How to fix this

Make sure `supportedVersions` includes at least one revision that is still current. A list containing only retired revisions leaves a modern client with nothing it can select.

Check your own server against this rule

The validator makes real protocol requests and reports this rule as pass, warn or fail alongside the other 78. Validate a server or read how the check works.
