Anlyon alternative

5 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.

  • add_to_cartAdd one rental to a real Sky High cart for a party date, delivery ZIP and hours, and get back a cart_id.No findings

    Why it is in this group

    • The name "add_to_cart" says "add": a word for a change.
    Description, as the server wrote it
    Add one rental to a real Sky High cart for a party date, delivery ZIP and hours, and get back a cart_id. Call build_quote first if the customer has not seen the price. To add more items to the SAME party, call again with the cart_id from the first call (one cart, one delivery fee). Safe to repeat: an item already in the cart is not added twice. Added is NOT reserved: nothing is held until the customer pays at checkout. Next step: prepare_checkout with the cart_id.

    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
    Build a complete, real quote for one rental on a specific date and delivery zip: exact dated item price, availability, delivery fee, that date's minimum order, the total, and the booking link. Use this the moment you know the product, the date and the zip - it is the fastest way to answer 'how much?' properly. If you are missing the date or zip, ask the customer for it (never guess a zip from their IP or city) and then call this.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Look up the delivery fee and minimum order for a Texas delivery zip code. Use when a customer asks what delivery costs or what the minimum order is for their area. ALWAYS pass event_date when the customer has mentioned their party date - minimum orders vary by date and the dated answer is exact. Without a date the answer is the general rule.

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

      annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "prepare_checkout" says "checkout": a word for a change.

      What this check looks for
    Description, as the server wrote it
    Get a cart ready for checkout. Re-checks that everything is still available for the date and that the cart meets that date's minimum, then returns the items, the price breakdown (delivery, fees, tax, total, deposit due today), what the customer still has to enter, and handoff_url: a private link that opens this exact cart at checkout on any phone or computer. This tool never pays or places the order: the customer pays on that page, or, once they have authorized it, you complete checkout there for them. Give handoff_url to the customer only.

    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
    Look up a Sky High rental product by name. Returns the page URL, units in stock, how many times families have booked it, and price. ALWAYS pass event_date (and zip when you know it) - with a date this returns the EXACT price for that date and whether it is available, which you should quote directly. Prices returned here are LIVE - prefer them over any knowledge-file price, and never send the customer to the product page to find a price this tool can give you.

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.

1 warn
  • Warnprepare_checkout

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

    What this check looks for

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.

Run in a terminal.

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": [],
    "ask": [
      "mcp__booking__product_info",

    ],
    "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 booking. Review it before you use it.

Pin

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

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
