Overview

What is Regulations.gov MCP?

A Model Context Protocol server that wraps the Regulations.gov REST API as deterministic tool calls. It provides eight tools covering federal rulemaking activity and is built for federal acquisition policy teams, regulatory affairs analysts, advocacy groups, FAR/DFARS Council watchers, and anyone tracking rulemaking dockets, public comments, or FAR cases.

How to use Regulations.gov MCP?

Install via uvx or pip install regulationsgov-mcp. You must obtain a free API key from api.data.gov (1,000 requests/hour) and set it as the environment variable REGULATIONS_GOV_API_KEY.
