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.

MCP
MCP server error messages now quote and sanitise the server name consistently.
What's wrong with this entry?
Anonymous. No account, no email.
What
Failure messages for reconnecting to an MCP server, or enabling and disabling one, now put the server name in double quotes and pass it through the same sanitizer used elsewhere.
Details
Where policy restricts what can be shown, the message still withholds the detail as before.
Evidence
Failed to ${r} MCP server "${Tr(o)}"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
