What cost-seg-smart does
The cost-seg-smart MCP server exposes two hosted tools for Cost Seg Smart, a US cost segregation study provider. It runs at https://costsegsmart.com/mcp and uses Streamable HTTP with JSON-RPC 2.0. No authentication is required for the endpoint.
get_cost_seg_quote calculates a study price from a supported property type and purchase price. It can also accept a tax bracket to estimate first-year tax savings and the return on the study fee. The calculation uses tier lookup and arithmetic rather than running a study engine, so it is intended for quick, repeatable estimates.
get_cost_seg_payment_link creates a Stripe Checkout URL for purchasing the study. The generated checkout data includes the property metadata and a disclaimer identifying the agent that prepared the order. After the buyer pays, the report is generated automatically and emailed within one hour.
How it works
Send tool calls to the hosted MCP endpoint over Streamable HTTP. The server accepts property categories including single-family rentals, short-term rentals, condominiums, accessory dwelling units, small and larger multifamily properties, offices, retail, industrial, mixed-use, medical offices, and restaurants. Supported values include codes such as sfr, str, condo, multifamily, office, and restaurant.
Study prices range from $495 to $13,995 depending on property category and purchase price. Properties priced at $25 million or more follow a custom-quote email path rather than the standard pricing flow.
An X-Agent-Name request header can identify the agent in the Stripe disclaimer. If the header is omitted, the disclaimer uses a generic AI-agent description. Use an accurate value because the field is intended as a legal and chargeback record.
Setup and configuration
Add the endpoint as a Streamable HTTP MCP server in a compatible client. Claude Desktop uses a transport value of streamable-http and the endpoint URL. Cursor accepts the URL in its MCP settings, and Claude Code can add it with:
claude mcp add cost-seg-smart https://costsegsmart.com/mcp
The server also provides a Smithery installation command for Claude. Client-specific configuration documentation is available at https://costsegsmart.com/mcp-server/.
No API key or other environment variable is required. Before creating a payment link, confirm the returned study_cost with the human buyer. The payment tool may request a buyer email or a Turnstile challenge for anonymous IP addresses.
Tools and capabilities
- Return the property label, purchase price, study cost, estimated first-year deduction, currency, and—when a tax bracket is supplied—tax savings and ROI multiple.
- Generate a browser-based Stripe Checkout URL for the selected study.
- Carry property information and the agent attribution into the purchase flow.
- Support repeated quote requests without running a study engine.
- Handle supported property prices from standard tiers and route qualifying high-value properties to custom quotation.
Limitations and notes
The cost-seg-smart MCP server does not perform the underlying cost segregation study; its quote tool provides estimates based on configured pricing tiers and arithmetic. The material describes the endpoint as an open commercial service, but Cloudflare rate limits still apply. Unrecognized user agents are limited to five requests per minute per IP, while recognized AI bot user agents receive up to 50 requests per minute per IP. Excessive sequential price-band enumeration can receive HTTP 429 with a Retry-After header.
The quote endpoint is open, while payment-link requests may encounter additional buyer-email or Turnstile requirements. Phase-two UCP checkout endpoints, AP2 signed mandates, and Stripe Shared Payment Tokens are not shipped. Separate REST and product-feed endpoints exist, but they are not MCP tools.
