Questions

Can I connect two Google Calendar accounts to Claude Code?

Yes. Connect each one in Manyplug under its own name, for example Work and Personal. Claude Code can use one of them or all at once.

Will Claude Code change anything in Google Calendar without asking?

By default these actions wait for your approval before they run: “Delete an event”. Other changes follow your rules, which you can make stricter per account.

Do I need an official Google Calendar MCP server for this?

No. Manyplug connects to Google Calendar itself (you sign in on Google Calendar’s page) and gives Claude Code the tools through one MCP address, together with your other services.

Is it free to connect Claude Code to Manyplug?

Yes. New workspaces get 14 days of Pro free, then the free plan keeps going with 150 actions a month and up to 3 connected accounts. No card needed. Paid plans start at $5 a month.

Does Claude Code see my passwords or API keys?

No. Keys are entered on Manyplug’s own pages, stored encrypted with a separate key per account, and the AI only receives tool results.
