What the UK Data: UK MPs and elections MCP server can do

The UK Data: UK MPs and elections MCP server is published by reliness.co.uk, a domain the MCP Registry verified. It has 8 tools. It can create or change data (7 tools: constituency_election_result, mp_contact_details, member_career_history, member_registered_interests and 3 more), but cannot delete data. 1 tool only reads.

8 tools bring in text other people can write (constituency_election_result, constituency_search, mp_contact_details and 5 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 write8
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
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.

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 uk-parliament-people. Review it before you use it.
