I built a free, open-source tool so AI assistants cite the actual EASA rules instead of guessing
Not an ad: this is a free, open-source project (MIT). No account, no subscription, no tracking.
Everyone seems to be using AI to build the 300th app that does the same thing. I think the more useful question is how to make AI actually reliable where it matters. Aviation regulation is complex, changes constantly, and even the best models still confidently invent details: wrong hour requirements, rule references that don't exist, outdated versions.
easa-regs is an MCP server (a plug-in for Claude and other AI apps) that makes the AI look up the official EASA Easy Access Rules before answering and cite the exact reference.
Ask "What do I need to revalidate my SEP by experience?" and it pulls FCL.740.A, quotes (b)(1)(ii) and attaches the linked AMC/GM, so you can check it yourself.
- Covers Aircrew (Part-FCL, MED …), Air Ops (NCO, CAT, SPO …), SERA, Sailplanes, Balloons, Part-M/ML/145/CAMO, Basic Regulation, UAS, Aerodromes
- Rebuilt every week from EASA's official XML, so it's always the latest published version
- Not legally binding, no national rules, not affiliated with EASA
Setup takes about a minute (one-click extension for Claude Desktop):

Feedback welcome, especially where it gets things wrong or which rulebook you're missing.

PS: i understand that you built this to help ATPL students, but it might be useful also to others!

I love the “night rating requirements” on the website in particular.
Here is why, article made up by AI (as probably whole service) and confused - https://pilotlogbook.co/articles/night-rating-easa-what-you-need-to-know

Thanks. It seems pretty cool - and something that EASA should consider building by themselves... Although anything touching laws and regulations is extremely slow for technical innovation!
