   Start Claude Code and ask it to use one of your services, for example “What's on my calendar today?”.

If it doesn't work

• claude mcp list shows “Needs authentication” until you sign in.
• If the browser can't hand the sign-in back, paste the full address from its address bar into Claude Code's prompt.
• Already added MegaMCPs on claude.ai? Claude Code signed in to the same Claude account loads it on its own.
