## Trust

- hygiene: 100
- liveness: 29
- freshness: 85

- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 86/100 (good)

### protocol: n/a (weight 25)

- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 10 of 10 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: rules_amending (idempotentHint); get_stats (idempotentHint); search_regulations (idempotentHint); …
- pass `tools.token_cost`: about 1,369 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 10, about 1,369 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/app.frtracker/regulatory-research.svg)](https://protogrid.dev/servers/app.frtracker/regulatory-research)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (10)

- `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.
- `get_requirement`: Detail for one extracted obligation by id, including its source rule and citation URL. Requires an API key.
- `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.
- `get_stats`: Aggregate corpus statistics: documents, obligations, pairs, agencies, coverage dates. No API key required.
- `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.
- `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.
- `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.
- `recent_cfr_changes`: Most recent detected changes to CFR text (title, part, name, dates), newest first. No API key required.
- `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.
- `search_regulations`: Full-text search over Federal Register documents and extracted obligations (FTS5/BM25). Totals are approximate (total_exact: false). Requires an API key.
