What needs a person

Approve the agent in the first place

access is granted by someone accountable for the agency

ask them to add the MCP connector and sign in, or to create a key under Settings → API keys

Grant access to Search Console or GA4

only the property's owner can add a user

get_google_service_account and ask them to add that address; then connect it yourself with connect_search_console_service_account / connect_google_analytics_service_account

Make a Yandex Webmaster token

it is minted in the site owner's Yandex account

get_connection_link with yandex_webmaster gives them the steps; connect what they hand you with connect_yandex_with_token

Connect by sign-in instead (and Business Profile, which has no other route)

it needs a sign-in to the client's Google or Yandex account

get_connection_link {clientId, service} and send them the link; check with get_client_integrations

Change the plan

it charges the agency

get_billing_link {plan} returns a checkout or billing-portal address for them to open

Make someone an owner

owners can do anything, including close the agency

ask an owner to do it in Settings → Team

Sign up a new teammate

an account is a person's own

ask them to sign up; then add_team_member {email, role}

Close the agency or export all its data

irreversible, or the whole account at once

ask an owner to use Settings → Ending this account or Data export
