What
MCP servers are outside programs that give Claude extra tools. Artifacts are a Claude Code Remote feature with their own server. When Artifacts are turned off, either in Claude Code settings or by a deny rule on Artifact, Claude Code now leaves out any MCP server set up to connect to the Artifacts server. A deny rule is a permission rule that blocks a tool.
That server is skipped with the note: "Ignored: Artifacts are turned off here (Claude Code settings, or a deny rule on Artifact), so this server, which connects to Artifacts, is not connected". Other servers' Artifact tools are also blocked.
Why
Turning off Artifacts now also closes the route through MCP servers, so a deny rule on Artifact cannot be bypassed that way. If such a server stops connecting, this is why.
