概覽

AI 產生的概覽

一個遠端 MCP 伺服器，可列出在兩個日期之間生效的美國聯邦最終規則，並依《聯邦公報》紀錄核驗相關說法。

可以做什麼
依兩個日期列出已生效的聯邦最終規則，依生效日期由近至遠排序，可依機關篩選，並附規則標題、修訂的 CFR 部分、DATES 段落及《聯邦公報》紀錄中的逐字引文。依文件編號取得某條規則的完整資訊，包括發布日期與 federalregister.gov 連結。列出各機關及其規則數量、最早與最晚生效日期。查找修訂指定 CFR 標題與部分的規則，例如 49 CFR 192。核驗關於規則生效日期、機關或所修訂 CFR 部分的說法是否與儲存紀錄和引文一致。
適用情境
適合需要了解某段時間內生效的美國聯邦規則、哪些規則涉及特定 CFR 部分，或核實某項生效日期、機關資訊是否正確時使用。適用於法遵、監管與政策研究，且答案可追溯至《聯邦公報》。
執行需求
需連線 referencesource.org 的遠端 streamable-HTTP 端點；未宣告需要帳號、API 金鑰或環境變數。README 另述可透過 npx 執行 npm 套件作為 stdio 橋接，需要 Node 18 或更新版本。需能存取該端點。
安裝前請注意
僅提供唯讀查詢，不會寫入、傳送或刪除資料。核驗結論只說明所存來源的陳述，不代表現實世界中即為事實；not_found 僅表示此登錄冊中沒有該項目。它只檢索自身已發布的紀錄，無法核驗任意網頁。適用標準伺服器請求日誌。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 US federal rules taking effect，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.joelp22-maker%2Freferencesource-rules/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

README

referencesource-mcp

[referencesource.org MCP connector]

MCP server for referencesource.org — small, verified reference datasets where every record carries its source URL and a verbatim quote from that page, so any value an assistant gives you can be checked, not just believed.

285 datasets, 110,000+ records: regulatory thresholds and deadlines, version compatibility, standards supersessions, certification registers, inspection requirements, and more. Each dataset states its coverage and its last-verified date.

Tools

toolwhat it does
list_datasetsevery dataset with record counts and descriptions
search_recordssearch within a dataset; each hit returns the value plus its source URL and verbatim source quote
get_recordone record by id, full provenance included
verify_quotegive it a dataset slug and a value you already hold (record id and field optional) — it checks that claim against our published records and says whether it matches

verify_quote is the unusual one: assistants invent plausible-but-wrong values roughly 19% of the time in our own measurements, and this is the check. Four verdicts come back:

verdictwhat it means
matches_recordthe claim equals the stored value; the match type is named (exact, case-insensitive, normalised)
matches_quotenot a stored value, but it does appear in the record's source quote
differsthe record holds a different value — both are returned, with the source
not_foundno record in that dataset carries it

Where a record is found, the answer carries the stored value, the record URL, the source URL and the verbatim quote, so the claim can be traced upstream — plus an attestation saying plainly that the verdict is about what our source states, not about what is true in the world. Asking whether the 2026 conforming loan limit for Autauga County, Alabama is $806,500 returns differs, stored value $832,750, quoting the FHFA row it came from.

Scope, stated so nobody overclaims: these tools search referencesource.org's own published records. They do not fetch arbitrary URLs and cannot check a claim against a page we have not harvested. not_found means "not in this dataset", never "false".

Setup

Claude Desktop — add to claude_desktop_config.json:

json
{  "mcpServers": {    "referencesource": {      "command": "npx",      "args": ["-y", "referencesource-mcp"]    }  }}

Cursor / other stdio MCP clients — same idea: command npx, args ["-y", "referencesource-mcp"].

Clients that support remote servers directly don't need this package at all — point them at the streamable-HTTP endpoint: https://referencesource.org/mcp.

Notes

  • Zero dependencies; Node 18+. The package is a thin stdio→HTTPS bridge to the stateless server at referencesource.org/mcp.
  • No accounts, no keys, no tracking beyond standard server request logs (see referencesource.org/privacy).
  • Data is free to read on the site in HTML, Markdown, and JSON; this package just makes it callable mid-conversation.

The data behind it

Every record carries source (the page the value was read from) and source_quote (the verbatim line on that page which states it), so any answer this server returns can be checked against its source. verify_quote runs that check against a value you already hold: it tells you whether our record agrees, and hands back the source and quote either way.

list_rules_taking_effect

List federal rules taking effect between two dates

What lands on me, and when? Lists already-published US federal final rules whose effective date falls between two dates, soonest first, optionally from one agency. Each with the rule title, the agency, the CFR parts amended, the document number, the rule's own DATES paragraph and a verbatim quote of the Federal Register record. This is the compliance-calendar question — use it for "what takes effect in Q4", not for searching the Federal Register by topic.

輸入參數to必填from必填limitagency

get_rule

Get one rule by Federal Register document number

Everything this register holds for one final rule: title, agency, effective date, the rule's own DATES paragraph, the CFR parts it amends, its publication date, a link to the rule on federalregister.gov, and a verbatim quote of the Federal Register API record it was read from. Document numbers look like "2026-13685" and appear in every other tool's results.

list_agencies

List the agencies with rules taking effect

Which agencies have rules coming? Returns each agency in this register with how many rules it has taking effect, the soonest and latest of those dates. Call it to get an agency name exactly as the Federal Register writes it before filtering with list_rules_taking_effect — "Federal Aviation Administration", not "FAA".

list_rules_amending_cfr_part

List rules amending a CFR part

Is anything changing in the part of the CFR I am subject to? Give a CFR title and part — "49 CFR 192", "40 CFR 52", "21 CFR 1308" — and get the already-published final rules that amend it, soonest effective date first, with each rule's DATES paragraph and a verbatim quote. The part is matched whole, so "40 CFR 5" never returns rules about 40 CFR 52.

verify_quote

Check a claimed fact about a rule against the register

Is this right? Check a claim about a final rule — its effective date, its agency, the CFR parts it amends — against the Federal Register record instead of trusting it. Says whether the claim matches a stored value, appears only in the verbatim quote, or differs (and then what the record says instead). Effective dates are exactly where a confident wrong answer costs money.
