2 tools here do something that can't be undone. Govern them.

Anlyon lists the tools and adopts none.
Each tool you adopt gets approvals and receipts.
Your agent never holds the key.

A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.

What the MRK Dubai Property MCP server can do

The MRK Dubai Property MCP server is published by mrk.ae, a domain the MCP Registry verified. It has 22 tools. It can do things that cannot be undone, such as sending, paying or publishing (calculate_purchase_costs and submit_enquiry) and create or change data (6 tools: ask, calculate_mortgage, rental_yield_estimate, golden_visa_eligibility and 2 more), but cannot delete data. 14 tools only read.

3 tools bring in text other people can write (search_listings, get_listing and submit_enquiry); 1 tool can send data out of your system (submit_enquiry).

The fixed checks matched 1 finding (annotation-conflict). Each one comes with the text it matched.

Its remote endpoint lists its tools without sign-in.

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.; get_listing
search_listings
submit_enquiry
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; submit_enquiry

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