Anlyon alternative

3 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.

    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
    One parcel's stored record and its checks: the county value, last sale, years held, lot, zoning line, water, outbuildings, the recorded signs an owner may sell, and (Colorado) every stored check such as tax delinquency, estate records, code cases, permits, wildfire and flood. Find it by shinnslist key, by street address (with ZIP when you have it), or by latitude and longitude.

    • Warn

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

      What this check looks for
    Description, as the server wrote it
    Run one proven signal adapter live at a point in Colorado or Virginia (see list_signals for the ids). Needs an API key (x-api-key; a free key from POST /api/keys) and counts against its daily quota; the aggregate tools above do not.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    How many parcels shinnslist tracks in a county, town or ZIP, with the count behind each buyer's trade (wholesaler, flipper, STR investor, developer, cash investor, land, family compound, realtor) and the as-of date. Counts come from county records, never estimates.

    Why it is in this group

    • The name "explain_grading" says "explain": a word for reading.
    Description, as the server wrote it
    How shinnslist grades itself, in plain words: personas open only after a hand check against county records, signals proven only by a test against their live source, the daily ranking graded against what actually sells, and how close the value estimate comes to real sale prices (the buyer-price floor is the bar). Returns the current numbers and the page to cite.

    Why it is in this group

    • The name "find_parcels" says "find": a word for reading.
    Description, as the server wrote it
    Find off-market parcels in a Colorado or Virginia county, town or ZIP from county records: who is likely to sell and why. Pick a trade for a buyer's list: wholesaler (absentee owners, held 10+ years, bought for under half of today's value), flipper (dated homes next to updated sales), str_investor (mountain-town homes with absentee owners), developer (land is most of the value), cash_investor and brrr (rent against value), land (empty lots), two_households (a family compound: room for two households), realtor (estate, tax lien, code case or stalled permit). Returns parcels with address, county value, last sale, years held and a shinnslist link; never owner names.

    Description, as the server wrote it
    Which counties and cities shinnslist covers, how many parcels each holds, how fresh they are, which buyer's trades are open, and how many signals are proven. Call it first when unsure whether an area is covered.

    Why it is in this group

    • The name "list_signals" says "list": a word for reading.
    Description, as the server wrote it
    The signals shinnslist has proven against their live public source, with the date, precision and recall of each proof. Only proven signals are listed; run one with run_signal. Nothing pending or planned appears here.

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 outbound.

Reads private data0
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.

1 warn
  • Warnrun_signal

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

    Matched text

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.

Claude Code permissions

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

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 shinnslist. Review it before you use it.
