Cost Seg Smart — MCP Server
Hosted Model Context Protocol server for Cost Seg Smart.
Lets Claude Desktop, Cursor, Claude Code, and any MCP-compatible AI agent get
cost segregation study pricing and generate Stripe checkout URLs without
scraping HTML.
Endpoint: https://costsegsmart.com/mcp
Transport: Streamable HTTP (JSON-RPC 2.0)
Auth: None — open commercial endpoint
This repo contains only the manifest. The server itself lives in a private
repository and is hosted on Railway behind a Cloudflare Worker proxy.
What it does
Two tools:
get_cost_seg_quote
Returns the price of a cost segregation study for a specific property, plus
Year-1 deduction and (if a tax bracket is provided) tax savings and ROI on
the study fee. No engine run — pure tier lookup and arithmetic. Safe to call
cheaply and repeatedly.
Example call:
Returns:
get_cost_seg_payment_link
Generates a Stripe Checkout URL the buyer can click to purchase the study.
Carries full property metadata + an explicit liability disclaimer naming the
agent ("Order prepared by [agent] on behalf of the cardholder..."). Buyer
completes payment in their browser; the report is generated automatically
and emailed within 1 hour.
Always confirm the study_cost with the human buyer before generating a
payment link.

Identifying your agent
When calling the endpoint, set the X-Agent-Name header so it appears in the
buyer's Stripe Checkout disclaimer:
If unset, the disclaimer reads "Order prepared by an AI agent on behalf of
the cardholder...". This is a legal/chargeback paper trail, not a marketing
field — please use accurate values.
