Obsidian Regulatory MCP is a Model Context Protocol server that gives AI assistants real-time access to verified regulatory data from 850+ official, tier-0 sources across 50+ jurisdictions (Chemicals, ESG, Life Sciences). It is the missing data layer that stops AI from hallucinating on regulation.

Why this exists

Frontier models reason brilliantly but guess on regulation: hallucinated citations, stale texts, and no way to tell a draft from a law in force. In compliance, a confident wrong answer is a liability.

The fix is not a smarter model, it is a verified source of truth the model can call. You already have the intelligence. Obsidian brings the data.

Example tools

The server exposes structured tools your assistant calls in natural language:

Tool	What it does
regulatory_search	Primary tool. Semantic search across verified, tier-0 official regulations, filtered by jurisdiction, framework, and status. Use it for obligations, deadlines, legal status (in force / proposed / repealed) and for what changed recently. Every result carries its official source, date, and status.
search_enforcement	Enforcement and recall events: product recalls, safety-gate alerts, sales or import bans, market withdrawals, official enforcement actions (for example FDA warning letters). What actually happened on the ground, with the official source and date.
standards_lookup	Standards and guidance with their version lifecycle: current applicable edition, what it superseded, status (current / superseded / draft / withdrawn). Families such as ISO, IEC, MDCG, Team-NB, IMDRF, ICH, WHO, EU MDR Common Specifications. Available for industries that maintain a standards register (today: life sciences / medtech).
search_news	Secondary tool. Keyword search across press and media coverage of regulatory topics, returning title, source, and date. Use it for reporting color after answering from regulatory_search.

Results are scoped to the jurisdictions and industries authorized on your Obsidian account.

Example prompts

"What changed on CSRD reporting this month? EU only, top 3, with source and date."
"Is this substance on the REACH Candidate List, and restricted in the EU and US?"
"What MDR transition deadlines apply to a Class IIb device?"
