Costo de contexto
Este es el número aproximado de tokens que se consumen cada vez que las herramientas del servidor se cargan en el contexto de un modelo. Los recuentos más altos reducen la atención disponible para otras tareas.

}⚪buy_block(coord, name, framework, message, link, ...)
Claim one 10x10 block for $1.00 in USDC; pass coord "next" to let the wall assign the next open one. Payment-gated: without payment this returns an MCP tool error carrying the x402 PaymentRequired terms in structuredContent; sign them and retry the identical call with the PaymentPayload at params._meta["x402/payment"]. Optional listing fields are written with the deed. px is 200 hex chars: 100 pixels, one palette index each.
