  • estimate_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 wit

  • calculate_appraisal_reduction

    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

  • get_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

  • size_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 CMB

Common questions

Is cmbs.loan: CMBS loan rates, lenders and servicing safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2026.1101.1) reached the registry 7 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
