Is the UK Data: GB road traffic counts (DfT) MCP server safe?

No scan can promise that. What its definitions show: 6 tools, 3 of which can change, send or delete something, and 1 finding from fixed checks. Allow the reads, ask before each change, and deny the deletes; the permissions block on this page does that.

Can the UK Data: GB road traffic counts (DfT) MCP server delete data?

No tool is classed as destructive: going by their definitions, none of them deletes, cancels or revokes anything.

Can the UK Data: GB road traffic counts (DfT) MCP server do things that cannot be undone?

No tool is classed as irreversible: none of them sends, pays, publishes or merges, going by their definitions.

What tools does the UK Data: GB road traffic counts (DfT) MCP server have?

6 tools: 3 write, 3 read. road_traffic_flow_at_point, local_authority_traffic_totals, region_traffic_by_vehicle_type, road_traffic_hourly_counts, traffic_local_authority_find and traffic_regions_list.

Anlyon lists the tools and adopts none.
Each tool you adopt gets approvals and receipts.

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: GB road traffic counts (DfT) MCP server can do

The UK Data: GB road traffic counts (DfT) MCP server is published by reliness.co.uk, a domain the MCP Registry verified. It has 6 tools. It can create or change data (3 tools: road_traffic_flow_at_point, local_authority_traffic_totals and region_traffic_by_vehicle_type), but cannot delete data. 3 tools only read.

6 tools bring in text other people can write (road_traffic_flow_at_point, road_traffic_hourly_counts, local_authority_traffic_totals and 3 more).

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.

Description, as the server wrote it
Gives the total distance driven on all roads in one GB council area each year, in million vehicle miles (and vehicle km), for all motor vehicles and for cars and taxis, plus the area's road length, newest year first. Answers "how much traffic is there in Leeds and is it growing" for council officers, net-zero and carbon plans, and consultants comparing areas. Minor-road traffic is a DfT estimate; this endpoint does not split vans, HGVs or buses (use region_traffic_by_vehicle_type for that at region level). (cost: 1 credit)

Description, as the server wrote it
Gives annual traffic in one GB region (English regions, Scotland or Wales) by vehicle type, in million vehicle miles: cars and taxis, vans, HGVs, buses and coaches, motorcycles and pedal cycles, plus road length, newest year first. Useful for market sizing (for example van or HGV traffic for fleet services), journalism and coursework.

Gives average annual daily flow (AADF) at one DfT count point: the average number of vehicles passing per day over a year, both directions together, split into cars and taxis, vans, HGVs, buses, motorbikes and pedal cycles, newest year first. Answers "how many cars pass this site a day" and "is traffic on this road rising" for shop, billboard, EV charger or planning work. Some years are estimated by DfT rather than counted, and each row says which; it does not cover live traffic or congestion. (cost: 1 credit)

Returns the hour-by-hour manual traffic counts DfT recorded at one count point on its survey day, by direction of travel, with each direction's busiest hour and 12-hour total. Answers peak-hour questions such as "how busy is this road at 8am" for transport consultants and planning statements.

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.
