Unclear It is not stated what the new check looks at or when it skips a server.

What

MCP servers are outside services Claude Code connects to for extra tools. Before connecting to each one, Claude Code now runs an extra check step that can skip the server. The usual checks, such as whether Claude Code is shutting down, whether the server is turned off, or whether it is blocked by managed policy, now run both before and after this step.

Why

This adds a point where an MCP server can be held back before Claude Code connects to it.
