MCP server connection and policy messages are now more informative and actionable:
Enterprise-blocked servers now show a distinct message: "This is an administrative block, not a connection failure — retrying will not help; an administrator manages this setting."
Failed-to-connect servers now explain: "Treat this as a connection failure — do not conclude the capability is unconfigured."
The /mcp panel now separately lists policy-blocked servers and connection-failed servers with explanatory headers
/mcp no longer references /doctor; settings/install issues now say "run claude doctor for details"
Evidence
Administrative block message (search for "This is an administrative block, not a connection failure") and new MCP status mapping (search for "run /mcp for details")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
How sure we are
One source agreesOne thing we can check says the same as this entry.
Anthropic's release notes agree/doctor is now a full setup checkup that can diagnose and fix issues; /checkup is its alias
