Unclear It is not clear whether such a server is actually blocked or only recorded.
What
An MCP server is an outside tool or data source Claude Code connects to. When an MCP server's name matches a desktop connector, Claude Code now records that the name was refused. Separately, when Claude Code swaps in MCP tools for an artifact and the entry is not being served, it now gives that as the reason.
Why
This suggests MCP servers using desktop connector names may be refused.
