Lex-Ray missed 3 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

about

about_this_server

What this MCP server is, what each access tier includes, and how to obtain access. Call this first if you are unsure what the server offers, or after any tool refuses you — the refusal names a tier, and this tool explains what that tier costs and what it adds. Requires no credentials.

instruments

search_instruments

Find EU legislation and UK legislation by keyword, acronym (GDPR, DORA, AIA), the common name practitioners use ('Market Abuse Regulation', 'MLRs', 'UK GDPR'), CELEX ID or Lex-Ray id. Matching is case-insensitive and an exact name ranks ahead of partial title matches. Returns an envelope whose 'matches' array carries the bibliographic record for each match — titles, id, jurisdiction (eu/uk), Official Journal reference, dates — plus a currency block giving the commencement state as at today, so a match that is expired or not yet applying says so rather than reading as current law. When several instruments share the exact name searched, 'ambiguous' is true and 'disambiguation' lists them: choose by jurisdiction and title rather than taking the first. When a curated common name settles it, 'preferred' names that act and 'alternatives' the others sharing the name. Use this to resolve a name to an id before calling the other tools. Requires no credentials.

legislation

get_legislation

Retrieve one act by CELEX ID, Lex-Ray ID, nickname, or uk-/eu- prefix. 'meta' is the bibliographic record (titles, dates, Official Journal reference, EuroVoc concepts, amendments and relationships to other acts) and needs no credentials. 'data' adds the parsed legal content — recitals, articles, annexes, definitions — and 'full' adds the rendered HTML. Every level carries a currency block: the day the answer was computed for, the commencement state on that day, and which version of the act is in force. Every answer also carries `pending_amendments`: proposals that propose to amend this act, each labelled in_flight / concluded / unknown, stamped with the reading date it was resolved against. These are PROPOSED, not enacted — never quote one as law.

Lex-Ray — questions

Answers built from our own checks of this server.

What can Lex-Ray do?

It exposes 3 tools, read directly from the server on our last check. Among them: about_this_server, get_legislation, search_instruments. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Lex-Ray working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 91 checks got a reply (97.8%), average response time 327 ms. The bar chart above shows every period we have measured.

How do I connect Lex-Ray?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Lex-Ray need an API key?

No. Lex-Ray completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Lex-Ray?

It answers our handshake in 327 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
