A rabbit taps a name into the screen,
Then picks the servers for its little team.
The gateway reads the saved design,
And serves the tools in ordered line.
Configured entries keep their place,
While refreshes bring new changes into space.
The rabbit hops away, its work complete.

Review comments at @internal/admin/handler_mcpvirtual.go:
- Around line 96-101: Update the upsert handler’s fallback after searching
mcpServers.VirtualViews() to return a 200 response with a body built from the
saved virtual.Spec(), rather than returning 204 when no matching view is found;
keep the existing mcpVirtualServerView response for matched views.
Review comments at @internal/mcpgateway/service.go:
- Around line 191-197: Serialize concurrent Reload calls by adding a reloadMu
mutex to Service and locking it for the full duration of Reload, releasing it on
every return.
Review comments at @internal/mcpgateway/virtual_admin.go:
- Around line 63-72: Normalize name at the start of DeleteVirtual by trimming
whitespace and converting it to lowercase before the managed-virtual check and
store deletion, so both use the same canonical name as UpsertVirtual.

Virtual MCP servers can now be created, edited, and deleted from the MCP Servers page. Changes apply immediately, without a restart. Until now they could only be declared in config.
