Cost Seg Smart MCP

An MCP server that allows AI agents to programmatically quote pricing, retrieve product catalogs, and generate payment links for cost segregation studies, enabling automated tax-savings estimates and checkout flows for real estate investors.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Cost Seg Smart MCP server. Use get_cost_seg_quote to price a property and estimate Year-1 deduction/tax savings. Use get_cost_seg_payment_link to generate a Stripe Checkout URL the buyer can click to purchase. Always confirm the price with the buyer before generating a payment link. The buyer's email is optional — Stripe will collect it at checkout if not provided.

Advertised read-only

Quote 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.

Open-world

Generate 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.
