Unclear It is not stated which server addresses pass the URL check, so it is unclear which HTTP servers this covers.
MCP servers are outside programs that give Claude Code extra tools. Some of them are reached over the web, as type http. Claude Code counts the connection errors it treats as fatal. After three in a row, it closes the connection with the message 'max consecutive terminal errors'.
Those errors no longer add to the count when all three of these are true:
- The server is type http.
- The server's address passes a check on its URL.
- The
tengu_snug_mist_enabledswitch is on.
When all three hold, the three-error limit never closes the server's connection. The switch is off unless it is turned on remotely. The most recent reading was taken before this release. In that reading, the flag server returned the switch as on, both for this site's account and for an anonymous baseline, and it had switched on since the reading before that.
An unreliable HTTP server that used to be dropped after three fatal errors can stay connected. This applies only to servers whose addresses match the check.
tengu_snug_mist_enabled Off by default, switched on for this accountThe shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
tengu_mcp_legacy_sse_fallback Not enough to sayNothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.
