What's Wrong?
Claude Code injects three claude.ai MCP servers on startup (claude.ai, claude.ai Gmail, claude.ai Google Calendar) without user opt-in. One of them — claude.ai Gmail — reports "needs authentication" on every startup, but it is impossible to authenticate because it does not appear in the /mcp panel.
What Should Happen?
I should see the gmail option if that's what I'm supposed to authenticate. Although why it's suddenly asking me to authenticate any gmail servers all of a sudden is a mystery.
