Is the UK Data: Science formulas MCP server safe?

No scan can promise that. What its definitions show: 7 tools, 7 of which can change, send or delete something, and 0 findings 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: Science formulas 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: Science formulas 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.

Does the UK Data: Science formulas MCP server need sign-in or OAuth?

Its remote endpoint listed its tools to an anonymous client, without sign-in.

Does the UK Data: Science formulas MCP server send data to outside services?

None of its tools sends, posts or publishes, or takes a recipient, channel or URL.

Has the UK Data: Science formulas MCP server changed its tools?

Not since anlyon.dev started tracking it. Last scanned Nov 7, 2026.

With Anlyon

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.

Govern this server →

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: Science formulas MCP server can do

The UK Data: Science formulas MCP server is published by reliness.co.uk, a domain the MCP Registry verified. It has 7 tools. It can create or change data (7 tools: project_population, calculate_electric_field, calculate_cell_density, calculate_bacterial_growth and 3 more), but cannot delete data. None of its tools only reads.

7 tools bring in text other people can write (project_population, calculate_electric_field, calculate_cell_density and 4 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.

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 write7: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; calculate_bacterial_growth
calculate_cell_density
calculate_electric_field
calculate_final_velocity
potential_energy
project_population
wire_resistance
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.

What this check looks for

Findings

Matches of fixed checks, with the text they matched.

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

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

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 science-formulas. Review it before you use it.
