What
MCP servers are outside programs that give Claude Code extra tools and data, including resources it can read. When Claude Code cannot read a resource because none of the connected servers lists it, the message now goes on to say ", or MCP skills are turned off".
Why
The message now names one more reason a resource might not be found, so you know to check whether MCP skills are turned off.
