Server tool list (2)

Raw names from tools/list. Only developers need these.

get_cost_seg_quoteQuote a CPA-ready cost segregation study for a US real estate property. Returns the study cost in USD, estimated Year-1 accelerated depreciation, and (when a tax bracket is provided) Year-1 tax savings and ROI on the study fee. Pure tier-matrix lookup — no engine run, no charge to the buyer, safe to call repeatedly. Use this before generating a payment link so you can confirm the price with the buyer. Does not provide tax advice.
get_cost_seg_payment_linkGenerate a Stripe Checkout URL for a human buyer to purchase a Cost Seg Smart cost segregation study. Returns a payment_link_url plus the study cost, property metadata, and a liability disclaimer naming the calling agent. The buyer must review the URL and authorize payment in their browser — this tool does not charge a card directly. Always call get_cost_seg_quote first and confirm the price with the buyer before generating the link. Side effect: creates a real Stripe Checkout Session.
