We built the missing piece of legal AI — and gave it away.
openlaw-mcp is a free Model Context Protocol server that connects Claude, Cursor, ChatGPT and Codex to real UK and EU law. Case law, legislation, FCA, ICO, HMRC, EUR-Lex, ECHR — every response carries a content-hash provenance envelope so the LLM can cite back, not hallucinate.
What you get
- 13 tools across 7 UK & EU open-law sources
- Streamable HTTP endpoint (preferred) + local npx + Docker
- Provenance envelope on every response (content_hash, source, licence)
- Point-in-time UK statute lookup
- Akoma Ntoso paragraph-precision case-law search
- OSCOLA / Bluebook citation formatting
Why we built it
Three reasons this is free.
Provenance is our home turf
Our governance product is built on the same idea: every AI output must trace back to a citable source. openlaw-mcp open-sources the part of that stack that the whole industry needs.
Free should mean free
No API key. No gated tier. No sign-up. The hosted endpoint costs us very little — it's a contribution, not a funnel.
It moves the field forward
Generic chatbots hallucinate case law and get firms sanctioned. We'd rather everyone use a grounded server (even ours) than another fabrication tank.
A look at the tools
The kinds of questions your AI can finally answer correctly.
search_caselawCase lawFull-text search of UK case law
Search The National Archives' Find Case Law (E&W courts and tribunals, 2001+). Filter by court, year, page.
fetch_judgmentCase lawFetch a judgment as structured Akoma Ntoso
Resolves a neutral citation or TNA URI to the full judgment XML, parsed into meta, header and paragraphs.
grep_judgmentCase lawRegex inside a judgment
Fetches a judgment, runs a JavaScript regex across paragraph text, and returns matching paragraphs with eId references.
citator_liteCase lawForward citation lookup
Find judgments on Find Case Law that cite a given neutral citation. No treatment classification.
lookup_statuteLegislationPoint-in-time statute lookup
Fetches a statute section from legislation.gov.uk, including version metadata, extent and commencement flags. Supports as_of date.

Returns parts, chapters and sections for an Act or SI from legislation.gov.uk's CLML contents XML.
How this fits with the paid platform
openlaw-mcp grounds your AI. LegalAI Space governs it.
The free MCP server gives any LLM cite-back-ready access to UK and EU law. The LegalAI Space platform layers governance on top: policies, verification, audit trails, COLP-ready reporting, and agents that run AI-curated legal work end-to-end under your firm's rules. Same provenance philosophy, dialled up for regulated practice.
