Use this MCP server to Federal Register documents, rules, notices, and agencies. Tools include...
The publisher's own server: Register.gy
Overview
Read-only MCP server that lets an assistant search the official Federal Register API for rules, notices, presidential documents and agencies.
- What you can do
- Search documents by term, document type, publication date range and page
- Retrieve a single document by its document number
- List the agencies represented by the API
- When to use it
- Useful when you need to look up US federal rules, proposed rules, notices or presidential documents, or check which agency published something, without leaving the assistant.
- Requirements
- Runs locally as a Node.js process installed from the npm package; no API key, account or environment variables are needed. Network access to the Federal Register API is required.
Installation
In SourceWeft
- Open Federal Register Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Other MCP clients
Follow the launch instructions in the repository.
