Cost Seg Smart MCP server

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:

getcostseg_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:

{
  "property_type": "str",
  "purchase_price": 750000,
  "tax_bracket": 0.32
}

Returns:

{
  "property_type": "str",
  "property_type_label": "Short-Term Rental",
  "purchase_price": 750000,
  "study_cost": 995,
  "deduction_estimate_year_one": 184500,
  "tax_savings_year_one": 59040,
  "roi_multiple": 59,
  "currency": "USD"
}

getcostsegpaymentlink

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 studycost 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:

X-Agent-Name: Claude

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.

Property types supported

sfr, str, condo, condostr, adu, duplex, triplex, fourplex, multifamilysmall, multifamily, multifamily5, office, retail, industrial, mixeduse, medicaloffice, restaurant

Price range: $495 to $13,995 depending on type and purchase price. $25M+ properties route to a custom-quote email path.
