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.

      What this check looks for
    Description, as the server wrote it
    Discounted departures of this site's yachts, read from the live inventory: only a discount the source itself states (a special, or a price under its list price), never a computed gap. By default from tomorrow to 30 days ahead; a departure the yacht's calendar shows taken is left out. One row per yacht: its page link (the id get and request_quote take) and photo (absolute URLs) and its departures, each with its dates, every route it leaves on, nights, price, list price, mandatory extras and saving, in the order asked. Narrow with the same typed filters as search. When none match, the answer is the nearest deals (the window after, the place around, a bound let go) and nearest says what was widened. Paged: total and cursor. Works without a contact (browsing: fewer rows).

    Why it is in this group

    • The name "request_quote" says "request": a word for a change.
    • The input addresses people (input.to): what it sends cannot be taken back.

    What it can reach

    • outboundThe input takes a destination (input.phone): what the tool writes goes there.
    Description, as the server wrote it
    Ask this site's desk for a formal quote on one or more yachts, for the person. Pass the page links a search, best_deals or get returned, the days and the party, and anything the person wants the desk to know. The desk answers with a written quote to the person's own email or phone, with every cost on it; this answer only says it was received and where the quote goes. Nothing is booked or paid: the person confirms the booking with the desk. Ask the person before calling 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.

    What it can reach

    • outboundThe input takes a destination (input.phone): what the tool writes goes there.
    Description, as the server wrote it
    What a stay typically costs: the range (p25, median, p75 in minor units of the currency) of open departures for a place, month and party, optionally one type, with how many items it is from, the cheapest published one that fits and when the figures were built; seasonNote says in words how another month compares. An unknown place answers with the places that have figures. Works without a contact.

    Why it is in this group

    • The name "get_yacht" says "get": a word for reading.
    Description, as the server wrote it
    One yacht: its facts and terms as the source states them (packages, included, required and optional extras, deposit, check-in days and times, stay limits, equipment, the operator's descriptions), and its availability: with from / to, that stay's status and price and, when it is not free, the nearest free stays; without dates, its free stays, soonest first. A field that is absent is one the source does not state. Works without a contact.

    Why it is in this group

    • The name "search_yachts" says "search": a word for reading.
    Description, as the server wrote it
    Find this site's yachts, read from the live inventory. Pass what the person wants as the typed filters, and from / to whenever they gave exact days. With dates it returns ONLY the yachts free for that stay, each with its stay: status, price, list price, discount and when the source was checked (checkedAt). Without dates each has its from-price. Every row carries its page link and one photo, absolute URLs on this site; send the person there. Narrow with the typed filters (each list is any of its values; every filter must hold); priceMin / priceMax count the mandatory extras a quote states. notApplied lists what could not narrow the search. When nothing matches exactly the answer is the nearest match, and nearest says what was widened (another week, the place around, a bound let go): tell the person. Paged: total and cursor. Works without a contact (browsing: fewer rows).

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.

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 out3
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
  • Warnbest_deals

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

    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.

All changes to this server

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

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": [
      "mcp__yacht-charter__search_yachts",
      "mcp__yacht-charter__get_yacht"
    ],
    "ask": [
      "mcp__yacht-charter__price_range",
      "mcp__yacht-charter__best_deals",
      "mcp__yacht-charter__request_quote"
    ],
    "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 yacht-charter. Review it before you use it.

Capability tags behind 3 rules

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