Hexadata Tools — business validation MCP server for AI agents

Hexadata Tools is a remote MCP server (Streamable HTTP, hosted on Apify) with 15 deterministic tools that an AI agent should call instead of guessing: check digits, official tables and official calculations. No LLM inside: the same input always gives the same answer, nothing is stored, and you pay per call ($0.005 per single call, $0.002 per item in batches; invalid input is free).
