Under the hood
MCP OAuth-token reuse now also requires the server's URL to match design-connector rules
What
When Claude Code decides whether an SSE or HTTP MCP (Model Context Protocol) server can skip its own OAuth check because a suitable access token already exists, it now also requires that server's URL to match the design-connector check before falling back to a generic OAuth probe.
Why
This narrows when an existing access token can be reused to satisfy an MCP server's authentication, tying that shortcut specifically to design-connector servers rather than any server with a token available.
