DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Improved MCP and enterprise-policy error messages

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.
