Perplexity

Pipe federal documents to Claude Code

The `search_federal_documents` tool enables you to query public rules directly from your terminal and pipe the output to grep or jq. Claude Code executes the query and formats the raw JSON for shell scripts. This setup turns your command line into a regulatory scanner. You can run quick checks or build cron jobs that monitor policy changes without opening a browser.

Automate CI/CD compliance checks

The `check_api_status` tool lets your terminal agent verify endpoint health before running automated integration tests. Claude Code checks the federal server status as a pre-flight step in your pipelines. If the service is active, the pipeline runs `get_federal_document_details` to pull down the latest rules for validation. This keeps your deployment workflows predictable and error-free.

Audit government agencies from the shell

The `list_federal_agencies` tool outputs a clean list of all departments publishing regulatory documents straight to your terminal. Claude Code parses this list to help you build targeted script filters. You can quickly isolate specific bureaus and feed their identifiers into your CLI search loops. The server delivers structured data that integrates perfectly with Unix command-line utilities.
