Obsidian Regulatory MCP

What Obsidian Regulatory MCP does

Obsidian Regulatory MCP MCP server gives AI assistants access to regulatory information collected from more than 850 official, tier-0 sources across over 50 jurisdictions. Its coverage includes chemicals, ESG, and life sciences topics, with examples such as REACH, CLP, TSCA, CSRD, ESRS, EU Taxonomy, CS3D, MDR, IVDR, FDA 21 CFR, and the AI Act.

Results include the originating source, publication or update date, jurisdiction, regulatory framework, and status. Status information can distinguish matters such as in-force, proposed, repealed, current, superseded, draft, or withdrawn, depending on the tool and result type. Account permissions determine which jurisdictions and industries are available.

How it works

The server is hosted at https://mcp.obsidianri.com/mcp and uses the Model Context Protocol over HTTP. An MCP client sends natural-language requests, while the assistant selects and calls the relevant structured tool.

The primary search path is regulatory_search, which supports semantic queries filtered by jurisdiction, framework, and status. search_enforcement focuses on events such as recalls, safety alerts, sales or import bans, market withdrawals, and official enforcement actions. standards_lookup returns standards or guidance together with lifecycle information, including current editions and superseded or withdrawn versions. search_news searches secondary press and media coverage and is intended to supplement, rather than replace, primary regulatory research.

Setup and configuration

Add the hosted connector URL to an MCP client, then complete the browser-based Obsidian sign-in flow. Claude Desktop and Cursor can use the URL as a custom connector. Claude Code can register it with:

claude mcp add --transport http obsidian-regulatory https://mcp.obsidianri.com/mcp

New accounts receive the free tier automatically, with no credit card required. The documented free allowance is 100 verified requests per month.

Tools and capabilities

The Obsidian Regulatory MCP MCP server exposes these documented tools:

• regulatory_search: Searches verified official regulations and supports filters for jurisdiction, framework, and status. It is intended for obligations, deadlines, legal status, and recent changes.
• search_enforcement: Finds official enforcement and recall events, including product recalls, safety alerts, bans, withdrawals, and FDA warning letters.
• standards_lookup: Looks up standards and guidance with version and lifecycle information. The README identifies current availability for life sciences and medtech industries.
• search_news: Searches press and media coverage by keyword and returns the title, source, and date.

Limitations and notes

The service is limited by the jurisdictions and industries authorized on the connected Obsidian account. The free tier permits 100 verified requests per month. search_news uses secondary coverage, so primary regulatory questions should be directed to regulatory_search first. ChatGPT and Perplexity are mentioned as clients as MCP support becomes available, but the documented connection steps cover Claude Desktop, Cursor, and Claude Code.

The repository states that the license applies to its documentation and configuration examples and identifies it as MIT. The hosted data service is accessed through an Obsidian account rather than a repository-local data installation.
