FedReg Tracker does not always answer
Over the last week it answered 12.1% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
regulatory
get_regulatory_deadlines
Upcoming comment deadlines or effective dates from the documents' structured fields, filtered by date range, agency, keywords, or one of your watchlists. Dates are calendar dates as published.
get_regulatory_document
Full structured record for one Federal Register document: status, agencies, publication/comment/effective dates, RINs, dockets, CFR parts, official links, linked rulemakings, deadline history, any earlier Public Inspection filing, and (when configured) the Regulations.gov docket title, comment period and posted comment count. Also finds documents still on Public Inspection.
get_regulatory_intelligence_brief
A structured, source-linked brief for one document: what happened, agency, status, who may be affected (from your watchlist when given), why it may matter, key dates, a suggested next step, sources, confidence and limitations. Built from source fields, not generated guesses.
get_regulatory_timeline
Lifecycle of a rulemaking: proposed rule, comment periods, extensions, final rule, effective date, corrections and withdrawals, with observed events and deadline history. Give a RIN, a rulemaking_id or a document_number. Links are 'confirmed' (shared RIN) or 'probable' (shared docket); missing stages are never invented.
list_regulatory_alerts
New alerts for this account's watchlists, highest priority first: new publications, Public Inspection filings (labeled prepublication), deadline extensions, effective-date changes, withdrawals, corrections and deadline reminders. Reading marks them delivered unless peek=true. An empty list means nothing new.
manage
manage_business_profile
Optional business profile used to suggest relevance: industries, NAICS codes, business size, regions, regulated activities, interests, federal contractor status. Give only what helps monitoring. action=get reads it.
manage_regulatory_watchlist
Manage this account's watchlists. action=list needs nothing else; other actions need watchlist (name or id). update accepts new filters, alert_preferences or new_name.
cfr
get_cfr_changes
Changes to codified CFR text from the eCFR (ecfr.gov): which sections got a new version, when (version, amendment and eCFR issue dates), whether eCFR marks it substantive or removed, links to the eCFR page and XML for that date, and Federal Register documents that probably made the change. Parts in watchlists are checked daily; any other part is read on first request. Give cfr_title and cfr_part (or a section like 63.2), or a watchlist with CFR filters. Version metadata, not a text diff; the eCFR is not the official legal edition.
compare
compare_regulatory_documents
Compare two Federal Register documents (or the latest proposed and final rule for a RIN): exact metadata differences plus sentence-level text differences with verbatim excerpts. Text comparison is labeled partial; it is not a legal redline.
federal
search_federal_regulations
Search U.S. Federal Register documents (final rules, proposed rules, notices, presidential documents) live from FederalRegister.gov. Filter by keywords, agency, document type, publication/comment/effective dates, CFR title and part, RIN, docket or industry. Every result states its legal status (a proposed rule is never binding) and official links. No account needed.
rate
rate_regulatory_alert
Tell FedReg Tracker how relevant a document was: relevant, not_relevant, high_priority, already_reviewed, more_like_this or stop_tracking (no more alerts for that document).
track
track_federal_regulations
Save a persistent watchlist. FedReg Tracker then monitors the Federal Register and Public Inspection on its own schedule and queues alerts and deadline reminders, with no chat open. Example: 'Track new cybersecurity regulations affecting federal contractors' → {name:'cyber-contractors', filters:{keywords:['cybersecurity'], cfr:[{title:48}]}}. Requires an access key.

FedReg Tracker — questions
Answers built from our own checks of this server.
What can FedReg Tracker do?
It exposes 12 tools, read directly from the server on our last check. Among them: compare_regulatory_documents, get_cfr_changes, get_regulatory_deadlines, get_regulatory_document, get_regulatory_intelligence_brief, get_regulatory_timeline and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is FedReg Tracker mostly used for?
Its tools cluster around regulatory and manage. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is FedReg Tracker working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 6 of 92 checks got a reply (6.5%), average response time 255 ms. The bar chart above shows every period we have measured.
How do I connect FedReg Tracker?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does FedReg Tracker need an API key?
No. FedReg Tracker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is FedReg Tracker?
It answers our handshake in 255 ms on average, which is faster than 63% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
