Artifact publishing now reports renamed MCP servers and warns about stale references to old names
When Claude Code parses MCP (Model Context Protocol, a way of connecting external tools/servers) capability manifests for artifact publishing, it can now merge duplicate manifest entries into one canonical connector and returns a renamed map showing old server names mapped to their new names. At publish time, Claude Code also checks the page's source code for any lingering references to the old server names and warns that calls using those old names will fail for viewers.
This catches a class of bug where a published artifact still calls an MCP server by a name that no longer exists after a rename or merge, which would otherwise silently fail for people viewing the artifact.
