Use it now Notable
--channels and its development-channels flag now require explicit plugin: or server: tags
What
Values passed to the --channels flag and to --dangerously-load-development-channels must now be tagged, in the form plugin:<name>@<marketplace> or server:<name>. An entry without one of these tags is now rejected with an explicit error explaining the required formats.
Why
Requiring the tag removes ambiguity about whether a channel entry refers to a plugin or an MCP server, catching malformed flag values immediately instead of letting them silently fail or resolve incorrectly.
