How to Use the Federal Register API MCP in Windsurf

Q: How does Windsurf use the Federal Register API to track rule changes?

Cascade calls searchfederaldocuments to scan recent filings based on your keywords. It then chains the results to pull full metadata automatically, saving you from manual searches.

Q: What happens if the Federal Register API goes offline during a Windsurf session?

Cascade uses checkapistatus to verify the endpoint is active before running queries. If the federal server is down, the agent alerts you instead of failing silently.

Q: Do I need to write custom scripts to parse the federal HTML links?

No, Cascade handles the raw output from getfederaldocumentdetails natively. It reads the metadata and extracts the links so you can review them in your IDE.

Windsurf's Cascade autonomously chains queries to track regulatory shifts and find documents without manual prompts.

Auto-track regulatory changes with Cascade

The `search_federal_documents` tool lets Cascade monitor federal rule changes and policy updates without you typing a dozen follow-up prompts. Cascade reads your target parameters, initiates the search, and tracks down matching documents in one clean motion. You don't have to guide this MCP Server through every step of the process. Cascade takes your high-level goal, scans the latest entries, and presents the relevant regulatory data directly inside your workspace.

Extract complete document details in Windsurf

The `get_federal_document_details` tool fetches raw HTML links and full metadata for any specific filing Cascade identifies during its runs. Cascade automatically pulls the exact document structure and formats it so you can inspect the legal text immediately. By letting the agent handle the deep dive, you bypass the manual portal entirely. The MCP connection feeds the exact publication details right into Cascade's active memory for instant analysis.

Map federal agencies autonomously

The `list_federal_agencies` tool gives Cascade a complete map of every government body publishing rules in the register. Cascade uses this list to filter searches and target specific departments like the EPA or SEC based on your project requirements. Before initiating any search, Cascade runs `check_api_status` to ensure the federal endpoints are responsive. If the service is up, the agent proceeds with mapping the regulatory environment without bothering you for permissions.
