Unclear It is not stated what the new check on a server tests, so it is unclear which servers now stay enabled.

What

MCP servers are outside programs that give Claude Code extra tools. Claude Code now skips disabling some MCP servers it would otherwise have disabled, when a new check on that server passes. The information Claude Code uses to decide tool permissions also now records which setting overrides an "always allow" rule for an MCP tool.

Why

This affects which MCP servers stay switched on and which of their tools are allowed without asking.
