The Pillar MCP server

• check_leaseFree

  Where a lease stands: awaiting_payment, in_review (paid, a person checks it first), live, refused (nothing charged), rejected_refunded, refunded (the slot was taken while paying), expired (the link ran out unpaid) or ended, with a plain message.

• find_windowsFree

  List the free ad windows on the tower, the free city billboards and the free casino game sponsorships, with monthly prices. Tower windows come first (floor 1 up, the cheapest floors first), then billboards (the most prominent first), then the casino's games: use kind to get only one of them, and maxPrice to cap the monthly price. Any floor, face or spot filter returns tower windows only. Pages hold up to 100 items; when next isn't null, pass it as cursor for the next page.

• get_pricesFree

  Every floor's monthly price for a middle and a corner window, and the price range of city billboards, in US cents. The listed price is exactly what Stripe charges.

• get_windowFree

  One window or billboard by id ("F47-S3" is floor 47, south face, column 3; "B-1234" is a city billboard): its monthly price and whether it can be leased now. When it can't, reason says why: taken (lit by a brand), reserved (paid, in review), paused, prize (a game prize, only its winner can lease it) or crown (never sold).

• start_leaseFree

  Start leasing a free window or billboard for a brand. The ad (website, name, pitch, logo) is checked first; a refused ad costs nothing. Returns checkoutUrl and leaseId: give checkoutUrl to the person, who pays the monthly price on Stripe within 60 minutes (you can't pay for them, and nothing is charged before they do). No account is needed: the window belongs to the email they pay with. Name, pitch and logo come from the website when left out. Then follow the lease with check_lease.
