api record

FRTracker (frtracker.app) tracks the U.S. Federal Register and Code of Federal Regulations, decomposing rules into individual binding obligations. Answers come only from its corpus; where evidence is insufficient, tools return explicit no-match or ambiguous results rather than guesses. Comment-to-change data is correspondence, not causation. Search totals are approximate. Tools marked as requiring a key need a free FRTracker API key sent as "Authorization: Bearer <key>" (get one at https://frtracker.app/developers); provision history, amendment lookups, CFR changes, and stats work without one. Cite FRTracker URLs from responses — they are stable and citation-grade.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_stats open 2h ago

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

  • list_obligations auth-required 2h ago

    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.

  • list_rules auth-required 2h ago

    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.

  • lookup_provision unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "q"
  ],
  "properties": {
    "q": {
      "type": "string",

    },

      "description": "Optional YYYY-MM-DD snapshot upper bound (not in the future)"
    }
  }
}
    arguments 16 lines
  • get_provision_history unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "canonical_id"
  ],
  "properties": {

  • rules_amending unknown never probed

    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.

  "type": "object",

    },

      "description": "CFR title number, e.g. \"40\""
    },
    "section": {
      "type": "string",
      "description": "Optional section id, e.g. \"52.2120\". Omit for all rules touching the part."
    }
  }
}
    arguments 25 lines
  • recent_cfr_changes unknown never probed

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

    mcp-tool

  "properties": {
    "limit": {
      "type": "integer",
      "description": "Max rows (default 50, max 200)"
    }
  }
}
    arguments 9 lines

    }
  }
}
    arguments 12 lines
  • get_rule_comments unknown never probed

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
