Anlyon alternative

8 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
Get the steps to book a hotel, cruise or experience found with search_trips. Geisel Power, the Virtuoso advisor, quotes it in writing within 24 hours (rate, taxes, the hotel's cancellation policy and the perks) and books only after the traveler approves. This tool sends nothing itself (request_sent: false). Hotel bookings carry no fee and nothing is charged by Stay Perks: the traveler pays the hotel directly.

Why it is in this group
- The name "create_booking_session" says "create": a word for a change.
What it can reach
- outboundThe input takes a destination (input.booker.phone_number): what the tool writes goes there.
Description, as the server wrote it
WRITE. Opens a UCP lodging booking session from a quoted offer (stay_id from get_availability_quote). Returns the authoritative total, the cancellation policy (show it to the traveler), the Virtuoso amenities, the payment term (pay at the hotel) and evidence. Nothing is charged; the session is held until the quote expires.
Annotations the server declares

search_availabilityWRITE.Reads text others writeNo findings
Why it is in this group
- The name "search_availability" says "search": a word for reading.
- The description's first verb is "write": a word for a change.
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
WRITE. Ask Geisel Power, the Virtuoso advisor, to price a stay at a Virtuoso hotel (property_id from search_trips). Virtuoso data carries no live rates, so pricing is asynchronous: this returns a quote id with status "pending" and a quote_due_by time (within 24 hours); poll get_availability_quote. A firm offer includes the full total, taxes and fees, the hotel's cancellation policy, and the Virtuoso amenities (e.g. breakfast for two, a hotel credit, an upgrade, subject to availability). Nothing is reserved or charged by this call, and hotel bookings carry no fee.

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 write3: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; cancel_booking_session
complete_booking_session
search_availability
Can send data out3: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; create_booking
create_booking_session
update_booking_session

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

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 stay-perks. Review it before you use it.
