get_v1_team_billing_plan

ReadPlan returns the plan and seat counts for the caller's OWN org, resolved from the VERIFIED team session token — never a client header. Seats and guests are the org's distinct active human members (a bot member is not a seat); the plan comes from the licensing entitlement and is empty when that read is unavailable, so the page shows an honest dash rather than a fabricated tier. A caller with no verified session gets 401, and a real seat-read failure is a 502 rather than a false "0 members".

Call it

A tools/call carries its arguments in one flat object. This tool declares none, so the object is empty.
