Show HN: Datatomcp – AI agents propose business definitions, a person approves

Datatomcp is an AI-native data layer that connects databases, apps and sheets into versioned datasets, links them by shared IDs, and drafts business definitions that a person must approve before agents can use them. Agents query through read-only MCP tools or a REST API, with exact totals computed by the database and every question recorded in an audit log. It is free for 3 datasets and 2 people, with Pro at €12/month, and is hosted in the EU.
