Under the hood
Chrome MCP config now determines bring-your-own-auth status by checking for non-DCR mode.
The Claude in Chrome MCP server config now determines bring-your-own-auth-server status by checking t.oauth.mode !== "dcr" instead of checking for mode === "byo". MCP OAuth entries using dynamic client registration (dcr mode) are no longer treated as bring-your-own-auth-server for egress-hostname purposes.
