What you get
Ten tools. Nine are pure math and run instantly; one answers CRE questions from a curated knowledge base with citations.
size_loanSizingMaximum supportable loan as the minimum of loan-to-value, debt service coverage, debt yield and loan-to-cost — plus which constraint binds.
run_scenarioSizingSweep the sizing across assumptions: a rate ladder, an NOI sensitivity table, or the feasibility of a target loan amount.
calculate_metricsMetricsNOI, cap rate, DSCR, debt yield, LTV, LTC, expense ratio, break-even occupancy and yield on cost — each returned with the formula used.
calculate_paymentMetricsAmortizing and interest-only debt service, total interest, and the balloon balance when the term is shorter than the amortization.
stress_testRiskRate shocks, income decline and combined scenarios with a pass, marginal or fail verdict on each — the tests a credit committee runs.
estimate_closing_costsTransactionItemized New York and Florida closing costs including mortgage recording and transfer taxes, with NYC and upstate priced separately.
analyze_cash_out_refinanceTransactionFull waterfall from maximum new loan down to net cash in hand, after payoff, prepayment penalty and closing costs. Includes NY CEMA savings.
compare_loan_offersComparisonRank competing offers by true cost of capital rather than headline rate, so a low rate carrying heavy fees sorts correctly.
search_cre_knowledgeKnowledgeSearch Relendi's curated CRE knowledge base and get source-cited excerpts on lending concepts, process and terminology.
ask_cre_questionKnowledgeAsk a plain-English commercial real estate question and get a short answer grounded in that knowledge base, with citations.
Try asking
- “Size a CRE loan: NOI $850,000, property value $12,000,000. Which constraint binds?”
- “Stress test an $8M loan at 7.25% over 30 years. Does it survive a 300bp shock?”
- “Estimate closing costs on a $5M refinance in Brooklyn, with $3M being paid off.”
- “Compare these two term sheets: 7% for 3 years with 3 points, versus 8% for 3 years with half a point.”
Your own deals
The public connector runs on numbers you type into the chat. Relendi accounts add the rest of the platform — lender matching, deal packaging, and a live pipeline your whole firm can see.
Privacy and limits
- No account data. The public endpoint has no code path to any customer record. That isolation is enforced by an automated check in Relendi's build, not by policy alone.
- Nothing stored. Figures you type are used to answer and are not saved against an account.
- Fair-use limits. The calculators are unmetered for normal use. The AI-backed question tool runs under a shared daily budget; when it is reached the calculators keep working.
- Read-only. No tool on this endpoint changes anything, in Relendi or anywhere else.
Frequently asked questions
What is the Relendi MCP server?
It is a Model Context Protocol (MCP) server that adds Relendi's commercial real estate calculators to an AI assistant such as Claude or ChatGPT. Once connected, you can ask the assistant to size a loan, run a stress test, or estimate closing costs in plain English, and it calls Relendi's deterministic math instead of estimating the numbers itself.
Do I need a Relendi account to use it?
No. The public endpoint at https://relendi.com/api/mcp/public requires no account, no sign-in and no API key. Add the URL as a custom connector and the tools appear. A Relendi account is only needed to run these tools against your own deals rather than numbers you type into the chat.
How do I add the MCP server to Claude?
In Claude, open Settings, then Connectors, then Add custom connector. Paste https://relendi.com/api/mcp/public and leave the OAuth fields empty, since the public endpoint needs no authentication. The Relendi tools then appear in your conversations.
How do I add the MCP server to ChatGPT?
In ChatGPT on the web, open Settings, then Apps, then Advanced settings, and enable Developer mode. Add a custom connector with the URL https://relendi.com/api/mcp/public and no authentication. Developer-mode connectors must also be enabled inside each conversation where you want to use them.
Is the loan math accurate, or is the AI estimating it?
The calculators are deterministic. Loan sizing solves the four standard constraints — loan-to-value, debt service coverage, debt yield and loan-to-cost — and returns the minimum along with which one binds. The AI assistant calls the tool and reports the result; it does not invent the figures. Closing-cost and cash-out tools use statutory New York and Florida rates rather than generic percentages.
What does it cost?
Nothing. The calculators are free and unmetered for normal use. The one AI-backed tool, which answers plain-English CRE questions from a curated knowledge base, runs under a shared daily budget; when that is reached it asks you to connect an account while every calculator keeps working.
Does Relendi see my deal data through this?
Not on the public endpoint. It runs entirely on figures you type into the chat and has no code path to any customer record — that isolation is enforced in the build, not by policy. Nothing you enter is stored against an account.
