4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

    Description, as the server wrote it
    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.

    Description, as the server wrote it
    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.

    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as commercial-mortgage. Review it before you use it.

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.
