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 answer links straight back to the real source, so the AI cites it instead of making it up.
What you get
- 13 tools across 7 UK & EU open-law sources
- Streamable HTTP endpoint (preferred) + local npx + Docker
- Every answer links back to the real source (source, hash, 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 invent case law and get firms sanctioned. We'd rather everyone — even people who never pay us — answer from real sources instead.
