Installation

In SourceWeft

  1. Open Commercial.Mortgage: programs, rates and loan sizer in the dashboard and add it to a workspace.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/mortgage.commercial%2Fcommercial-mortgage/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

size_loan

Size a commercial mortgage

The largest commercial mortgage a property supports under a lender type's loan-to-value, DSCR and debt-yield limits, which test binds, the monthly payment, and the resulting LTV, DSCR, debt yield and cap rate. Same math and defaults as the site's loan sizer; omit lender_type to size the deal under all five lender types.

get_rates_by_lender_type

Indicative commercial mortgage rates by lender type

Indicative commercial mortgage rate ranges for banks, life companies, CMBS, agency and debt funds: each lender type's index today (Treasury or 30-day SOFR, with its date) plus its spread range from a named, dated public source. Banks have no public spread source, so no range is given for them.

Parameterslender_type

get_spreads_by_property_type

Commercial mortgage spreads by property type

Permanent-loan spreads over the 10-year Treasury by property type (multifamily, industrial, retail, office) on 60 to 65% LTV loans, from CRED iQ as of March 31, 2026, plus the indicative rate at today's 10-year yield. Hotel, self storage, medical office and mixed use have no public source and say so.

Parametersproperty_type

get_index_rates

Treasury, SOFR and prime today

The latest 5-, 7- and 10-year Treasury yields, overnight and 30-day average SOFR, and the bank prime rate that commercial mortgages price from, each with its observation date, the value a week earlier, the change in basis points and its publisher.

Takes no parameters.

match_programs

Match a deal to commercial mortgage programs

Rank the commercial mortgage programs (agency, FHA/HUD, bank, credit union, life company, CMBS, bridge, debt fund, DSCR, construction and more) that fit a deal, with the reasons and cautions for each, today's indicative rate (live index plus the program's published spread), and an estimate of the largest loan each program's published LTV/LTC, DSCR and debt-yield limits allow. Programs that do not fit are listed with the reason. Same rules as the site's /find-your-loan/ matcher.

program_rules

Rules and limits of one commercial mortgage program

Everything published about one commercial mortgage program: eligible property types and loan purposes, minimum and maximum loan, maximum LTV and LTC, minimum DSCR and debt yield, term, amortization, rate type, recourse, prepayment, timeline, today's indicative rate, who it fits and who should look elsewhere, and the programs to compare it with. Every figure carries its as-of date and primary source (Fannie Mae, Freddie Mac, HUD, SBA, eCFR, SEC filings and others). Limits that are not published say so.

Parametersprogramrequired

compare_programs

Compare commercial mortgage programs side by side

Two or three commercial mortgage programs side by side: today's indicative rate, loan size range, maximum LTV and LTC, minimum DSCR and debt yield, term, amortization, rate type, recourse, prepayment and timeline, each figure dated and sourced, plus the site's head-to-head comparison page when one exists.

Parametersprogramsrequired

get_rates

Indicative rates for every commercial mortgage program

Today's indicative rate for every commercial mortgage program that has a published spread: the live index (Treasury, SOFR or prime, with its date) plus the program's spread range from a named, dated source, lowest first. Filter by property type, purpose or program family. Programs with no public spread are listed as such instead of guessed.

Parametersfamilypurposeproperty

prepayment_estimate

Estimate a commercial mortgage prepayment penalty

Estimate the prepayment premium on a commercial mortgage: Fannie Mae-style yield maintenance (Form 6104.01, annual discounting), Freddie Mac yield maintenance (monthly), CMBS yield maintenance, a defeasance cost estimate, a Fannie Mae declining (step-down) schedule, or an SBA 504 debenture premium. Treasury yields default to today's readings, interpolated to the time left. Same math as the site's prepayment calculator; schedules and minimums come from the verified loan-document facts.
