A validation toolkit that exposes JSON schema checking, email deliverability tests, and URL verification through MCP tools. Built by MEOK AI Labs with RFC-compliant validation logic and heuristic analysis under the hood. You get discrete tools for validating structured data, testing if emails are deliverable (not just well-formed), and checking URL reachability. Install via pip or uvx, then call validate_json, validate_email, or validate_url from Claude. Useful when you're building agents that need to verify user input, check API payloads, or gate workflows on data quality before passing values downstream. Ships with EU AI Act compliance documentation if you're in a regulated environment.
