What
The mcp_read_resource request reads a resource from an MCP server, an outside tool Claude Code connects to. It now has one more refusal: in a cloud session, which runs on a remote machine, it refuses to read resources from MCP servers that belong to your computer or your browser.
Why
A session running in the cloud can no longer pull resources off your local machine this way.
