Anlyon alternative
1 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.

estimate_home_equityThe same preliminary analysis, for when someone wants to know their estimated home equity and combined loan-to-value.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it The same preliminary analysis, for when someone wants to know their estimated home equity and combined loan-to-value. Works from approximate values the user gives for an Ontario residential property; Clara calculates the result in process and takes no contact details or documents. Results include the assumptions and caveats behind them. A preliminary scenario only, not an eligibility decision, a lender offer or an approval.

Why it is in this group
- The name "analyze_mortgage_scenario" says "analyze": a word for reading.
Description, as the server wrote it Preliminary analysis of a mortgage, refinancing, home-equity or debt-consolidation scenario: estimated equity, current and proposed combined loan-to-value, missing information and broad, unranked financing categories. Useful as a first look at someone's situation. Works from approximate values the user gives for an Ontario residential property; Clara calculates the result in process and takes no contact details or documents. Results include the assumptions and caveats behind them. A preliminary scenario only, not an eligibility decision, a lender offer or an approval.

Why it is in this group
- The name "get_financing_options" says "get": a word for reading.
Description, as the server wrote it The same preliminary analysis, for when someone wants to know which broad kinds of financing they could explore. Categories are unranked and are not lender offers.

Why it is in this group
- The name "search_published_mortgage_rates" says "search": a word for reading.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Searches the Ontario mortgage rates lenders have published, as recorded by Open Mortgage Rates, using filters such as mortgageType, term, position, minimumLtv, purpose or a lender keyword; with no filter it asks what to search for instead of listing every record. Returns each lender's own rate wording with its conditions, check date and source link, and a notice that goes with them. Useful when someone asks what rates lenders are publishing. It takes filters only, not names, contact details or dollar amounts. Published information, not a quote, offer, recommendation or eligibility assessment.

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 outbound.
- Reads private data1
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write1
- 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 open-financial-mortgage-options. Review it before you use it.
