Provide a sandbox for registry
Is your feature request related to a problem? Please describe. See many 'test' mcp servers (15 of as this writing) with the word 'test' - indicating people are testing against production registry and probably not cleaning up.
Describe the solution you'd like Would like to have a test registry similar to the production endpoint that can be periodically flushed.
I haven't dug into whether this will really work for the above / if it's a good idea (because it might be less stable / on a different version), but we do have a staging environment that gets reset every 24 hours at:
https://staging.registry.modelcontextprotocol.io/docs
The staging instance for registry team could be and should be different from staging for registry clients testing their integrations. No?
Yeah probably in an ideal world, although figured this might be a good temporary solution.
Fwiw I don't think other registries have a similar concept - e.g. NPM suggests just publishing with an alpha version to prod: https://github.com/npm/www/issues/72
