Five questions, answered in ChatGPT

Read the transcript

This is Duneland Financial inside ChatGPT. Six read-only tools, the same arithmetic as the calculators on dunelandfinancial.com. Every result is illustrative, and every result links back to the site. A buyer asks whether a two and a half million dollar business with seven hundred thousand of SDE can carry the debt. ChatGPT calls check deal affordability. Senior loan, two million. Cash flow for debt service, five hundred twenty thousand. DSCR one point seven one. These are model results, not financing approval. How does the whole purchase get funded? Four and a half million price, seven fifty of equity, a six hundred thousand seller note. Build capital stack solves the senior loan as the remainder: three and a half million, no funding gap, and it shows the worst year of coverage. What does a three and a half million loan cost at nine and a quarter percent over ten years? Model acquisition loan returns the monthly payment, the first year of service, total interest, and confirms there is no balloon. A five hundred thousand seller note, interest only, five years. Model seller note shows the payment, the twenty percent share of price, and the full five hundred thousand due at maturity. One owner is a green card holder. Is an SBA seven a loan an option? Screen SBA eligibility returns a constraint, cited to the SBA policy notice. It never says eligible. And when the question is not an acquisition, nothing fires. A state capital, a home mortgage, a stock pick: ChatGPT answers on its own. Results are illustrative, not a financing commitment. Duneland Financial does not lend. Continue any result on dunelandfinancial.com.

Claude, Cursor and other MCP clients

The tools speak the Model Context Protocol over streamable HTTP, with no authentication. Point your client at the endpoint:

https://dunelandfinancial.com/api/mcp/

In Claude Code, one line:

claude mcp add --transport http duneland-financial https://dunelandfinancial.com/api/mcp/

In clients that support a streamable HTTP JSON configuration:

{
  "mcpServers": {
    "duneland-financial": {
      "type": "streamable-http",
      "url": "https://dunelandfinancial.com/api/mcp/"
    }
  }
}

Gemini and Perplexity accept the same endpoint in their connectors settings. Gemini Enterprise lets an administrator register it for a company.

The six tools

Each tool wraps one calculator on this site, so an answer in a chat and an answer on the page come from the same arithmetic. Every result carries the same disclaimer and links back to the calculator with your inputs filled in.

What the tools do not collect

The tools take figures: a price, earnings, a rate, a term. They do not ask for your name, your contact details or your Social Security number, and they store nothing. The SBA screen takes yes-or-no answers about ownership; its result link carries none of them. Theprivacy policy and the terms of usecover the tools wherever they run.

Illustrative results for planning. Not a financing commitment, financial advice or legal advice.

When the numbers raise a question

The tools show what a structure costs. They do not say whether a lender will fund it. For that conversation, the support page has every way to reach us.
