How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security66
  • The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
  • Authorisation not fully verified: no authorisation is required to call this server, and 7 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
  • HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
  • The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
  • DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
Schema Quality & AI Usability78
  • 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 2535 tokens (~281/item across 9 items; 7 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
  • Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Tokens
regulations_browse_cfr ~329

Explore the codified Code of Federal Regulations via eCFR in two modes. "structure" walks the CFR hierarchy (all 50 titles, or one title's chapters → parts → sections) to discover a cite when the exact citation is unknown. "search" runs a full-text query across the codified CFR and returns matching sections with their hierarchy path and a snippet. Both modes feed regulations_get_cfr_section. The source (mirror or live) is reported on each search result.

NameTypeReqDescription
datePoint-in-time date, ISO 8601 (YYYY-MM-DD). Defaults to current. Structure mode uses this date for historical hierarchy; in search mode, a past date enables point-in-time search.
modestringyes"structure": browse the CFR tree (titles, or one title's chapters/parts/sections) to find a cite. "search": full-text search the codified CFR for sections matching a phrase.
partstringCFR part within the title (structure mode, optional) — narrows the returned tree to one part's sections. Parts can be alphanumeric.
per_pageintegerResults per page in search mode (1–50, default 20). Ignored in structure mode.
queryFull-text search phrase (search mode, required in that mode). Ignored in structure mode.
titleintegerCFR title number (1–50). Structure mode: omit to list all 50 titles, or provide to expand one title. Search mode: optional filter to restrict to one title.
NameTypeReqDescription
datestringResolved point-in-time date (structure mode).
modestringyesWhich mode produced this result.
nodesarrayHierarchy nodes at the requested level (structure mode).
noticestringGuidance when nothing matched.
resultsarrayMatching CFR sections, this page (search mode).
shownnumberResults returned on this page (search mode).
sourcestringProvenance: the synced mirror index, or the live eCFR search fallback (search mode).
totalCountnumberTotal search matches before pagination (search mode).
truncatedbooleanTrue when search results were capped at per_page.

No examples provided.

regulations_find_comments ~453

Fetch public comments on a Federal Register document or a Regulations.gov docket — the unique corpus of what citizens and organizations actually submitted. Provide exactly one targeting parameter: docket_id (all comments in a docket, broadest), document_object_id (comments on one document, from regulations_get_docket), fr_document_number (convenience — resolves the FR number to its Regulations.gov document internally), or comment_id (one comment's full detail and attachments). The list endpoint returns no body text or attachment info — call with comment_id to read a comment's body. When a comment's real content is a PDF/DOCX attachment, the body is a stub and attachmentOnly is true; the attachment download URLs are returned. Requires REGULATIONS_GOV_API_KEY (free at https://api.data.gov/signup/).

NameTypeReqDescription
comment_idstringFetch one comment's full detail and attachments by its Regulations.gov comment ID (e.g. "EPA-HQ-OAR-2025-0194-31102"). Use to read a single comment's body after finding it in a list.
docket_idstringFetch all comments in a docket by docket ID (e.g. "EPA-HQ-OAR-2025-0194"). Broadest scope. One of docket_id / document_object_id / fr_document_number / comment_id is required.
document_object_idstringFetch comments on one specific document by its Regulations.gov object ID (the objectId from regulations_get_docket's documents). Comments usually attach to the docket's primary (proposed-rule) docume…
fr_document_numberstringConvenience: fetch comments for a Federal Register document by its FR number (e.g. "2025-14555"). Resolves to the Regulations.gov document internally. Saves a get_document → get_docket hop.
pageintegerPage number (1-based). Regulations.gov caps a query at 20 pages (5,000 records); for a high-volume docket this surfaces a sample — narrow by document_object_id.
per_pageintegerComments per page (5–250, default 25). Regulations.gov requires a minimum page size of 5.
NameTypeReqDescription
attachmentOnlybooleanTrue when attachments exist and the body is a stub/empty — the substance is in the attachment files (detail mode).
attachmentsarrayAttachment files — substance lives here when attachmentOnly is true (detail mode).
bodyTextComment body, HTML-stripped. A stub ("See Attached") when content is in attachments; null when empty (detail mode).
commentIdstringComment ID (detail mode).
commentOnDocumentIdDocument the comment was filed on, or null (detail mode).
commentsarrayComments matching the target, this page (list mode). Bodies/attachments require comment_id detail mode.
docketIdDocket ID, or null (detail mode).
modestringyesWhich mode produced this result.
noticestringGuidance — empty results, or that bodies need comment_id detail mode.
organizationSubmitter organization, or null (detail mode).
postedDatestringPosted date (detail mode).
receivedDateReceived date, or null (detail mode).
restrictReasonReason the comment is restricted, or null (detail mode).
shownnumberComments returned on this page (list mode).
submitterNameSubmitter name when public, or null (detail mode).
targetstringWhat was queried — docket / document / FR doc (list mode).
titlestringComment title (detail mode).
totalCountnumberTotal comments matching the target (list mode).
truncatedbooleanTrue when comments exceed the 5,000-record ceiling (list mode).
withdrawnbooleanTrue when the comment was withdrawn (detail mode).

No examples provided.

regulations_get_cfr_section ~290

Read the codified text of a specific CFR section (or a whole part) via eCFR — current or as of a past date. Answers "what does 40 CFR 50.1 say today?" and "...as of 2019-01-01?". Provide title + part + section for one section, or omit section to fetch the whole part (large parts can be very long; prefer a specific section when you know it). eCFR retains historical versions back to roughly 2017; a date before coverage is rejected with guidance. Current single-section reads are served from a synced local mirror when available; the source is reported.

NameTypeReqDescription
datePoint-in-time date, ISO 8601 (YYYY-MM-DD). Default current. eCFR retains historical versions back to ~2017; a date before coverage is rejected.
partstringyesCFR part within the title (e.g. "50"). Parts can be alphanumeric. Obtain from regulations_browse_cfr or a Federal Register document's cfrReferences.
sectionSection identifier within the part (e.g. "50.1"). Omit to fetch the entire part — large parts can be very long; prefer a specific section when you know it.

titlenumberyesCFR title number.

No examples provided.

regulations_get_docket ~319

Pull a rulemaking docket from Regulations.gov by docket ID (e.g. "EPA-HQ-OAR-2025-0194") — the docket's metadata (title, agency, RIN, abstract) and the documents filed in it (NPRM, final rule, supporting materials). The docket is the folder holding a rule's whole paper trail; each returned document's objectId feeds regulations_find_comments. A docket often contains hundreds of supporting materials — filter document_types to "Proposed Rule"/"Rule" to find the rule documents themselves. Requires REGULATIONS_GOV_API_KEY (free at https://api.data.gov/signup/); the Federal Register and eCFR tools work without it.

NameTypeReqDescription
docket_idstringyesRegulations.gov docket ID (e.g. "EPA-HQ-OAR-2025-0194"). Obtain from a Federal Register document's docketId (regulations_get_document) or an agency rulemaking reference.
document_typesarrayFilter the docket's documents to these types. Omit for all. A docket often contains hundreds of "Supporting & Related Material" items — filter to "Proposed Rule"/"Rule" to find the rule documents.
pageintegerPage number (1-based). Regulations.gov caps a query at 20 pages (5,000 records); beyond that, narrow with document_types.
per_pageintegerDocuments per page (5–250, default 25). Regulations.gov requires a minimum page size of 5.
NameTypeReqDescription

titlestringyesDocket title.
truncatedbooleanTrue when documentCount exceeds the returned set / 5,000 ceiling.

No examples provided.

regulations_get_document ~196

Fetch one Federal Register document by its FR document number — full metadata (title, type, agencies, abstract, action, effective/comment dates, RINs) plus the cross-source handles that make this a workflow server. The output carries the docket ID (chain into regulations_get_docket or regulations_find_comments) and the affected CFR parts (chain into regulations_get_cfr_section). Set include_full_text only when the rule body itself is needed — final rules can run tens of thousands of words.

NameTypeReqDescription
document_numberstringyesFederal Register document number (e.g. "2025-14555"). Obtain from regulations_search_rules results (the documentNumber field).
include_full_textbooleanWhen true, fetch and inline the document body as plain text (can be large). Default false returns the body URLs only; fetch full text only when you need to read the rule itself, not just its metadata…

typestringyesDocument type.

No examples provided.

regulations_list_open_comments ~266

List rules currently open for public comment, filterable by agency slug and topic, sorted by closing date (soonest first). "What can I still weigh in on?" Runs on the Federal Register's open-comment window and is fully functional without a key. When REGULATIONS_GOV_API_KEY is configured, each row is enriched with the comment count from the Federal Register document's embedded Regulations.gov info (no extra rate-limited call). Open one row with regulations_get_document for the full proposal, or pull the comments with regulations_find_comments.

NameTypeReqDescription
agenciesarrayFilter to one or more agencies by Federal Register agency slug (e.g. "environmental-protection-agency").
closing_beforeOnly rules whose comment period closes on or before this date, ISO 8601 (YYYY-MM-DD). Use to find deadlines you need to act on soon.

shownnumberResults returned on this page.
totalCountnumberyesTotal rules open for comment matching the filters.
truncatedbooleanTrue when matches exceed the FR 5,000-record navigation ceiling.

No examples provided.

regulations_search_rules ~418

Search the Federal Register — the daily journal of US proposed rules, final rules, notices, and presidential documents (1994–present) — filtering by full-text query, document type, agency slug, publication date range, and whether the rule is open for comment. The primary discovery entry point: results carry the document number (open with regulations_get_document), docket IDs, RINs, and affected CFR parts that chain into the comment and codified-text tools. The Federal Register caps navigation at 50 pages and the match count at 10,000; when a result set is larger, narrow with published_after/published_before rather than paging deeper.

NameTypeReqDescription
agenciesarrayFilter to one or more agencies by Federal Register agency slug (e.g. "environmental-protection-agency", "securities-and-exchange-commission"). Slugs are the kebab-case agency name; if unsure, search…
