What
When Claude Code authenticates to a first-party MCP server, it now records whether the token came from a normal login or from a login carrying the Design connector's extra user:design:read scope. The kind of token last used is passed into connection-failure diagnostics, so a failure can be told apart by which credential was in play.
Details
- Which kind applies depends on whether your login has the
user:design:readscope.
