API and MCP
The regulatory data layer for your AI. Connected in two minutes.
Models reason brilliantly but guess on regulation: made-up citations, outdated texts, a draft mistaken for the rule in force. Obsidian is the verified data layer your AI queries. Connect it to Claude, ChatGPT or Cursor: every answer comes back current, cited and checkable.
This regulation is not about PFAS (it sets ecodesign rules for local space heaters), and no universal ban is in force.
The same question, without and then with the Obsidian MCP (example taken from our MCP page).
