Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

rules

list_rules

List Federal Register documents with filters: agency slug, document type, rulemaking pathway (interim_final/temporary/direct_final = notice-and-comment bypass classes), or docket id. Requires an API key.

rules_amending

Which final rules amend a CFR part or section, read from each rule's own amendatory instructions ("Amend § 52.2120 by..."). Returns the rules, the sections each addresses, and dates. This reports what a rule SAYS it amends — it is not an attribution of any observed text change to that rule. Covers 2020-present; absence means not indexed, not that no rule amended it. No API key required.

lookup

lookup_provision

Look up a CFR provision by citation (e.g. "21 CFR 1304.04") or by an exact quotation, optionally as of a past date. Returns the provision text with a ProvisionEvidence object (source, snapshot date, hashes). Explicitly reports ambiguity or no-match instead of guessing. Requires a free API key.

obligations

list_obligations

List extracted regulatory obligations ("who must do what") with filters: agency, deontic class, free text. Obligations are machine-extracted with quality tiers; they are not legal advice. Requires an API key.

provision

get_provision_history

Documented change history for a CFR provision by canonical id (e.g. "21-cfr-1304.04(a)"): before/after text, computed redline, observed dates, and candidate final rules. 404 when the provision is not in the documented-change set — absence of a documented change is not a claim that nothing changed. No API key required.

recent

recent_cfr_changes

Most recent detected changes to CFR text (title, part, name, dates), newest first. No API key required.

regulations

search_regulations

Full-text search over Federal Register documents and extracted obligations (FTS5/BM25). Totals are approximate (total_exact: false). Requires an API key.

requirement

get_requirement

Detail for one extracted obligation by id, including its source rule and citation URL. Requires an API key.

rule

get_rule_comments

Public comments for a Federal Register document (organization, title, date, body where available). Coverage is partial and stated in the response. Requires an API key.

stats

get_stats

Aggregate corpus statistics: documents, obligations, pairs, agencies, coverage dates. No API key required.

Is FRTracker — Federal Regulatory Research working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 341 ms. The bar chart above shows every period we have measured.

Is FRTracker — Federal Regulatory Research still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect FRTracker — Federal Regulatory Research?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does FRTracker — Federal Regulatory Research need an API key?

No. FRTracker — Federal Regulatory Research completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is FRTracker — Federal Regulatory Research?

It answers our handshake in 341 ms on average, which is faster than 45% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
