Anlyon alternative

Run the operations that matter 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 it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Lists the units on one Booking Bench site that can be booked for a stay: open every night and within the unit's minimum stay, maximum stay, arrival and departure rules and guest capacity. checkIn and checkOut are required. guests defaults to 2, and the answer says when the default was used. Optional filters: city (a town on that site), minBedrooms, minBathrooms, amenities (all must be listed), petsAllowed. sort is fit (smallest unit that sleeps the party, then bedrooms, then name; the default), price, or name. No result is ranked by payment. Each result has propertyId, name, city, state, sleeps, bedrooms, bathrooms and averageNightlyRate (per night over the stay, before cleaning fee and taxes). The answer gives returned, totalMatches (or totalMatchesAtLeast when not every unit was checked), nextCursor, refinements (unused filters with how many units would remain) and notes. More than 10 matches return the best 5. Availability is up to 5 minutes old; get_quote is live.

    Why it is in this group

    • The name "list_sites" says "list": a word for reading.
    Description, as the server wrote it
    Lists live Booking Bench sites that have rental units in or near a destination city in the United States, nearest first, five per page. `city` is the destination the traveler names, never the traveler's own location. Each result has siteSlug, siteName, matchedCity, distanceMiles (straight-line, whole miles, between town centers), the cities the site has units in, and numberOfProperties. The answer states how many sites match in all (totalMatches) and gives nextCursor when more exist. Sites at the same distance are ordered by a daily rotation. A city name used in several states returns candidates; a misspelling returns suggestions.

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 data3
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write6
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.

No check matched anything in these tool definitions. That is not a safety guarantee.

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 booking-bench. Review it before you use it.
