Regulations.gov — Claude Code MCP server
This MCP server lets an agent work with Regulations.gov dockets, documents, comments, comment periods, and readiness checks.
claude mcp add --transport http regulations-gov-mcp https://regulations-gov.1102tools.com/mcpWhat Regulations.gov does
The server exposes nine tools for working with Regulations.gov. An agent can inspect rulemaking dockets, review their documents and comments, check comment periods, and examine whether materials are ready for the next step.
Claude Code can use either a hosted HTTP connection or a local process started with uvx regulationsgov-mcp. The local setup requires REGULATIONS_GOV_API_KEY; without that variable, this installation path will not work. The hosted endpoint is https://regulations-gov.1102tools.com/mcp.
The installation commands also cover Codex, Cursor, GitHub Copilot, Gemini CLI, and the other listed platforms. Once connected, the agent can query Regulations.gov while handling a task instead of relying on a separate browser session.
What it helps with
- search rulemaking dockets by topic
- check when a comment period closes
- review documents attached to a docket
- collect comments for a proposed action
- assess whether submission materials are ready
Example prompts for the agent
- Search Regulations.gov for the relevant rulemaking docket and list its documents.
- Check the comment period for this docket and report the dates.
- Gather the comments and related documents for this Regulations.gov matter.
