7 tools here change things. 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 UK Data: US vehicle safety (NHTSA) MCP server can do

The UK Data: US vehicle safety (NHTSA) MCP server is published by reliness.co.uk, a domain the MCP Registry verified. It has 10 tools. It can create or change data (7 tools: vehicle_recalls, recall_campaign_details, vehicle_complaints, vehicle_crash_ratings and 3 more), but cannot delete data. 3 tools only read.

10 tools bring in text other people can write (vehicle_recalls, recall_campaign_details, vehicle_complaints and 7 more).

None of the fixed checks matched anything in its tool definitions. That is not a safety guarantee.

Its remote endpoint lists its tools without sign-in.

Last scanned Nov 7, 2026, version 1.5.0.

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.
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.

Matches of fixed checks, with the text they matched.

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