Sends an email with a Review connection button; the user presses that button, then "Yes, connect" on the page that opens (opening the page alone does nothing).

check_signup Poll after start_signup. Returns { status: "pending" } until the user presses the button in the email, then { status: "ready", apiKey, setup } exactly once; the pollToken is dead after that. The setup field holds the exact config or command for this client plus what to tell the user (restart, or remove-and-re-add on Desktop). Poll every 5 seconds for up to 15 minutes without ending your turn. On ready, apply the setup snippet at once, then call create_client for the product.

start_signup Start signup without leaving the agent. Ask for the user's email, do not invent one. Sends an email with a Review connection button; the user presses that button, then types the userCode this tool returns and presses "Yes, connect" on the page that opens (opening the page alone does nothing). Show the user the userCode exactly as returned. That lets check_signup return an API key for this MCP client. Returns a pollToken for check_signup.
