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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    Why it is in this group

    • The name "search_listings" says "search": a word for reading.

    What it can reach

    • untrusted-inputThe description's first sentence says "search" and "website": it reads web pages, which anyone can write.
    Description, as the server wrote it
    Searches active NYC rental listings from StreetEasy, LeaseBreak, NYBits, Reddit, and building websites, plus lease takeovers posted on Buzzedin. Supports price, bedrooms, neighborhoods, boroughs, move-in dates, commute time to an address, distance to places (subway, grocery, a named store), amenities, rent-stabilized buildings, lease takeovers, and apartment qualities like natural light or quiet. Returns up to 8 listings with a deal-score estimate, how each rent compares to its neighborhood median, selected structured features such as laundry, outdoor space, pets and light, plus a public detail link for each apartment. Enrichment and deal scores are estimates; confirm details on the listing. Fetch the next page to see more results.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false

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
  • Warncreate_alert_link

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

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "create_alert_link" says "create": a word for a change.

    What this check looks for

History

Claude Code permissions

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

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__nyc-apartments__search_listings"
    ],
    "ask": [
      "mcp__nyc-apartments__create_alert_link"
    ],
    "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 nyc-apartments. Review it before you use it.
