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/loan.cmbs%2Fcmbs-loan/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.

special_servicing_timeline

CMBS special servicing timeline

The contractual sequence after a missed monthly payment or a missed balloon on a CMBS loan, day by day: transfer to the special servicer, SEC delinquency status codes, the appraisal reduction trigger and deadline, the 120-day maturity window, each with its PSA section. Give days_elapsed to get which events have already been triggered and the next one with days remaining.

Parameterstriggerrequireddays_elapsed

estimate_special_servicing_fees

Estimate CMBS special servicing fees

Special servicing, workout and liquidation fees on a CMBS loan for one outcome (loan corrected and paid at maturity, refinanced within 120 days of a missed maturity, or liquidated/discounted payoff), using the fee terms of a real 2025 pooling and servicing agreement: 0.25%/yr with a $3,500 monthly minimum, 1% workout fee with a $25,000 minimum, 1% to 3% liquidation fee. Returns each fee, the monthly fee and the total.

calculate_appraisal_reduction

CMBS appraisal reduction amount

Appraisal Reduction Amount for a delinquent CMBS loan from a new appraisal, using the formula in a 2025 pooling and servicing agreement: balance minus (90% of appraised value + reserves - unpaid interest, advances and other amounts due). Returns the value side, the reduction, the share of scheduled interest the servicer keeps advancing, and the 25% deemed reduction that applies if no appraisal arrives in time.

get_cmbs_rates

Current CMBS loan rates

Median original note rates on CMBS loans securitized in the last 90 days, 180 days and 12 months, from SEC Form ABS-EE loan data, overall or for one property type, with the middle half, loan counts, the 5- vs 10-year split and recent months. Rates on closed loans, not a quote.

Parametersproperty_type

get_cmbs_underwriting

CMBS underwriting medians

What CMBS lenders actually underwrote in the last 12 months, from SEC loan data: loan size, loan to value, debt service coverage, debt yield and occupancy (median and percentiles), interest-only share and 5/10-year term mix, overall or for one property type.

Parametersproperty_type

find_cmbs_lenders

Find CMBS lenders

CMBS originators ranked by loan volume over the last 12 months, from the originator named on each loan in the trusts' SEC filings. Filter by property type, state and loan amount (keeps lenders whose securitized loan sizes span it). Returns volume, loan count, size range, median rate, leverage and a page per lender.

Parameterslimitstateloan_amountproperty_type

get_cmbs_lender

One CMBS lender's book

One CMBS originator's securitized book from SEC filings: 12- and 24-month volume, loan sizes, median rate, leverage, property types, states and its most recent loans (property, city, amount, rate, term, trust). Give the lender's name or slug, e.g. "Citi" or "wells-fargo".

Parameterslenderrequired

get_cmbs_maturity_wall

CMBS maturity wall

CMBS loans still reporting, by maturity year: count, balance, average note rate and the share whose NOI at securitization is under 9% of today's balance (a rough refinance-gap proxy), compared with today's median new-loan rate. Overall, by property type or by state (one filter at a time).

Parametersstateproperty_type

size_cmbs_loan

Size a CMBS loan

Maximum CMBS loan on a property under the three sizing tests lenders apply, and which one binds: loan to value x value, NOI / (DSCR x annual debt constant at the rate and amortization, or the rate if interest-only), and NOI / debt yield. Limits you omit default to what recent CMBS loans stayed within (90th percentile LTV, 10th percentile DSCR and debt yield, by property type), and the rate to the 90-day median.
