A straightforward JSON Schema validator that works with draft 7, 2019-09, and 2020-12 specs. You can validate JSON documents against schemas and generate schemas from example JSON, which is handy when you're reverse-engineering APIs or need to formalize data structures on the fly. Built by MEOK AI Labs with pip or npx installation. The repo emphasizes EU AI Act compliance features like bias detection and transparency tracking, so if you're building in regulated spaces or need audit trails around data validation, that's baked in. MIT licensed and part of their broader governance-focused MCP ecosystem.
