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.

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

The server marks "calculate_flip_profit" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

Description, as the server wrote it Runs the fixandflip.loans calculator on a deal: profit, cash you put in, return on cash (and simple annualized), profit as % of ARV, the hard-money loan with interest, points and fees, holding and selling costs, the 70% rule maximum price and whether the deal meets it, and the breakeven sale price. Optionally prices the loan at a listed lender's advertised starting rate.

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 write3
- 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.
Remote posture

The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

Claude Code permissions
Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

"permissions": {
"allow": [
"mcp__fixandflip-loans__compare_lender_costs",

],
"ask": [

],
"deny": []
}
}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 fixandflip-loans. Review it before you use it.
