Maito uses Cal.com to do the work and replies where you asked.
How to connect Cal.com
Open Connections in your workspace and choose Connect next to Cal.com. You sign in to Cal.com in a new tab, and that's the whole setup. Name the account and choose Workspace under who can use it. That's the only time anyone signs in: your whole team, shared chats and Loops can use Cal.com from then on. Or skip ahead and ask for the work: Maito sends you a link if Cal.com isn't connected yet.

Cal.com publishes it at https://mcp.cal.com/mcp, and it signs in with OAuth, so there's no key to copy.
Yes. Connect it to Maito once, then mention Maito in any Slack channel or send it a direct message. The same connection works by email and from Claude, ChatGPT, Cursor, Codex, Grok or Muse.
No. One person connects it once and chooses Workspace. Then everyone in the workspace, shared chats and Loops can use Cal.com, without signing in themselves. Choose Only me instead to keep it to your own chats.
No. If a request needs Cal.com and it isn't connected yet, your agent sends you a link. Connect it, and the work picks up where it stopped.
Yes. After you connect, turn off any Cal.com tools you don't want Maito to use, such as the ones that change data. Tools Cal.com adds later stay off until you turn them on.
