US Law MCP Server

The eCFR and US Code alternative for the AI age.

Query 130 curated US federal statutes and regulations -- from HIPAA and CCPA to SOX, GLBA, FERPA, COPPA, FISMA, and more -- directly from Claude, Cursor, or any MCP-compatible client.

If you're building legal tech, compliance tools, or doing US federal compliance research, this is your verified reference database.

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

US compliance research means navigating eCFR (ecfr.gov), uscode.house.gov, and agency guidance across dozens of federal departments, reconciling statutes with implementing regulations, and manually checking for amendments in the Federal Register. Whether you're:

• A compliance officer checking HIPAA obligations, CCPA requirements, or SOX controls
• A lawyer validating citations in a brief or contract
• A legal tech developer building tools on US federal compliance law
• A researcher mapping US regulatory requirements against international frameworks

...you shouldn't need dozens of browser tabs and manual cross-referencing. Ask Claude. Get the exact provision. With context.

This MCP server makes US federal compliance law searchable, cross-referenceable, and AI-readable.

Coverage note: The database covers 130 curated statutes and regulations -- a compliance-focused subset of US federal law, not the complete US Code. The selection prioritises data protection, cybersecurity, financial regulation, healthcare, and cross-border compliance topics most relevant for enterprise compliance work.
