Context Cost

~1,100Tokens (tool definitions)
~2.6 KBTypical response size
Moderate attention impact (0.86% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

⚪vibecart.create_checkout(productId, quantity, items)

Creates a hosted checkout URL for one or more trusted merchant-catalog products. Legacy productId + quantity input remains supported; new integrations should use items[]. VibeCart resolves all prices server-side. This can contact Stripe but never charges by itself; the customer must complete Stripe Checkout.
