US Regulations MCP Server

Navigate US compliance from the AI age.

Query HIPAA, CCPA, SOX, GLBA, FERPA, COPPA, FDA 21 CFR Part 11, EPA RMP, FFIEC, NYDFS 500, and 4 state privacy laws (Virginia CDPA, Colorado CPA, Connecticut CTDPA, Utah UCPA) directly from Claude, Cursor, or any MCP-compatible client.

If you're building healthcare tech, consumer apps, or financial services for the US market, this is your compliance reference.

Built by Ansvar Systems — Stockholm, Sweden

Why This Exists

US compliance is scattered across regulations.gov PDFs, eCFR.gov pages, state legislative sites, and agency guidance documents. Whether you're:

• A developer implementing HIPAA security controls or CCPA consumer rights

• A product team navigating breach notification requirements across multiple states

• A compliance officer mapping NIST controls to regulatory obligations

• A legal researcher comparing incident response timelines across federal and state laws

...you shouldn't need to navigate fragmented federal agencies, 50 state legislatures, and conflicting PDF formats. Ask Claude. Get the exact section. With context.

This MCP server makes US regulations searchable, cross-referenceable, and AI-readable.

Why This Works

Verbatim Source Text (No LLM Processing):

• All regulatory text is ingested from official sources (eCFR.gov, California LegInfo)

• Snippets are returned unchanged from SQLite FTS5 database rows

• Zero LLM summarization or paraphrasing — the database contains regulation text, not AI interpretations

• Note: HTML-to-text conversion normalizes whitespace/formatting, but preserves content

Smart Context Management:

• Search returns 32-token snippets with highlighted matches (safe for context)

• Section retrieval warns about token usage (some sections can be large)

• Cross-references help navigate without loading everything at once

Technical Architecture:

eCFR/LegInfo HTML → Parse → SQLite → FTS5 snippet() → MCP response
                      ↑                    ↑
               Formatting only      Verbatim database query

Example: regulations.gov vs. This MCP

regulations.gov example: Download HIPAA PDF → Ctrl+F "breach" → Read §164.410 → Google "What's a 'reportable breach'?" → Cross-reference CCPA → Check California site → Repeat for SOX

This MCP: "Compare breach notification requirements across HIPAA, CCPA, and SOX" → Done.

⚠️ Important Disclaimers

Legal Advice

🚨 THIS TOOL IS NOT LEGAL ADVICE 🚨

This tool provides regulatory text for research and educational purposes. However:

• Control mappings (NIST 800-53, NIST CSF) are interpretive guidance, NOT official HHS, NIST, or agency crosswalks

• Applicability rules are generalizations, not legal determinations

• Cross-references are research helpers, not compliance mandates

Always verify against official sources and consult qualified legal counsel for compliance decisions.

Data Source Transparency

📋 Source Quality Disclosure

Tier 1 - Official API Sources (Authoritative):

• HIPAA, GLBA, FERPA, COPPA, FDA 21 CFR 11, EPA RMP — sourced from eCFR.gov official API

• CCPA/CPRA — sourced from California LegInfo official site

Tier 2 - Official State Sources (HTML Scraping):

• Virginia CDPA — sourced from law.lis.virginia.gov

• Connecticut CTDPA — sourced from cga.ct.gov

• Utah UCPA — sourced from le.utah.gov

• Colorado CPA — seed data verified against leg.colorado.gov

Tier 3 - Seed Data (Verified but Static):

• FFIEC IT Handbook — examination guidance extracted from ffiec.gov booklets

• NYDFS 500 — regulatory text from dfs.ny.gov

• SOX — statute and SEC implementing regulations

Seed data sources include official source attribution and verification dates. Users should check official sources for updates.

Control Framework Mappings: HIPAA-to-NIST and CCPA-to-NIST mappings are interpretive guidance to assist compliance research. They are NOT official agency crosswalks. Consult NIST SP 800-66 and official agency guidance for authoritative mappings.

Token Usage

⚠️ Context Window Warning

Some regulation sections can be large (e.g., HIPAA Privacy Rule sections with extensive commentary). The MCP server:

• Search tool: Returns smart snippets (safe for context)

• Get section tool: Returns full text (may consume significant tokens)

• Recommendation: Use search first, then fetch specific sections as needed

Claude Desktop has a 200k token context window. Monitor your usage when retrieving multiple large sections.

MVP Status

📋 Initial Release

This is a production-ready MVP with three foundational regulations (HIPAA, CCPA, SOX). The database schema and all 9 MCP tools are fully functional and thoroughly tested (100% test coverage).

Data Ingestion: Automated ingestion from official API sources (eCFR.gov, California LegInfo) is operational. Additional regulations are being added to the database.

Coming Soon: Additional federal regulations (GLBA, FERPA, FISMA) and state breach notification laws.

NIST Standards

No copyrighted NIST standards are included. Control mappings reference NIST 800-53 control IDs only (e.g., "AC-1", "SI-4"). While NIST standards are freely available from NIST, this tool helps map regulations to controls but doesn't replace reading the standards themselves.

Available Tools

The server provides 9 MCP tools:

Architecture Overview

Database

The server uses SQLite with FTS5 (full-text search) for efficient querying:

• regulations - Metadata for each regulation

• sections - Regulation sections with full text

• sections_fts - FTS5 index for fast full-text search

• definitions - Official term definitions

• control_mappings - NIST control to regulation mappings

• applicability_rules - Sector applicability rules

• source_registry - Data source tracking for updates

Ingestion Framework

The ingestion framework uses an adapter pattern to normalize data from multiple US regulatory sources:

• eCFR.gov API - Electronic Code of Federal Regulations (HIPAA, SOX)

• California LegInfo API - State legislation (CCPA/CPRA)

• regulations.gov API - Federal regulatory documents

• Agency-specific sources - HHS, SEC, FTC guidance

Each adapter handles source-specific pagination, authentication, and data normalization.

MCP Protocol

The server implements the Model Context Protocol specification:

• stdio transport for Claude Desktop integration

• Centralized tool registry for consistent tool definitions

• Structured error handling with informative messages

• Token-efficient responses with snippet highlighting

How They Work Together

Regulations → Controls Implementation Workflow:

1. "What are HIPAA's security safeguard requirements?"
   → US Regulations MCP returns 45 CFR § 164.306 full text

2. "What security controls satisfy HIPAA §164.306?"
   → Security Controls MCP maps to NIST 800-53, ISO 27001, and SCF controls

3. "Show me NIST 800-53 AC-1 implementation details"
   → Security Controls MCP returns control requirements and framework mappings

Complete compliance in one chat:

• EU/US Regulations MCPs tell you WHAT compliance requirements you must meet

• Security Controls MCP tells you HOW to implement controls that satisfy those requirements

About Ansvar Systems

We build AI-accelerated threat modeling and compliance tools for automotive, financial services, and healthcare. This MCP server started as our internal reference tool for US regulations — turns out everyone building for US markets has the same compliance research frustrations.

So we're open-sourcing it. Navigating federal and state regulations shouldn't require a legal team.
