Terminal-driven regulatory queries with Claude Code

The `search_documents` tool lets Claude Code query the official federal database directly from your command line. You can pipe Federal Register search results directly into local scripts, making it easy to automate compliance checks in headless Claude Code environments. Here’s the deal: Claude Code uses `get_document` to pull the precise text of any regulation without opening a browser. This raw federal text can be redirected to local files or parsed by other CLI utilities in your Claude Code workflow.

Headless pre-publication monitoring via MCP Server

The `get_current_public_inspection` tool allows Claude Code to fetch documents scheduled for publication from your terminal. This is perfect for terminal-based cron jobs that need to check for compliance updates every morning using Claude Code. By using `search_public_inspection`, Claude Code filters the pre-publication queue for specific keywords. If a match is found, Claude Code uses `get_public_inspection_document` to extract the text and trigger downstream CLI alerts.

Scriptable agency lookups in Claude Code

The `list_agencies` tool provides Claude Code with a clean list of all federal regulatory bodies. You can run quick lookups in your terminal to find specific agency slugs without wading through slow government web portals. Once Claude Code has the slug, it uses `get_agency` to retrieve contact details and active document counts. This structured Federal Register metadata is immediately available to be formatted as JSON or piped into other terminal tools by Claude Code.
