check_domain_availabilityCheck whether one domain name is free to register.Reads text others writeNo findings
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
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it
Check whether one domain name is free to register. Answers from the public registry for that ending: available, unavailable (taken) or unknown (that ending cannot be checked here). Takes one full name such as yourbrand.com.ng. When it can be ordered online, gives the first-year price. Prices are in US dollars outside Nigeria and in naira in Nigeria; pass currency to choose.

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 outbound.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write10: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; check_domain_availability
create_domain_order
create_esim_order
create_proxy_order
fetch
list_esim_locations
list_proxy_products
search
search_esim_plans
search_phone_plans
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.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

WarnThe whole server
The endpoint served tools/list without credentials, and the list has 5 tools that change things (5 write). Whether a call also works without credentials was not tested: tools are never called.
Matched text
https://www.xpressflowsystems.com.ng/api/mcp: tools/list returned 12 tools to an anonymous client, including check_domain_availability (write), create_domain_order (write), create_esim_order (write), create_proxy_order (write), create_wallet (write)

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 esim-domains. Review it before you use it.

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.
