概览

AI 生成的概览

一个远程 MCP 服务器，可列出在两个日期之间生效的美国联邦最终规则，并依据《联邦公报》记录核验相关说法。

可以做什么
按两个日期列出已生效的联邦最终规则，按生效日期由近及远排序，可按机构筛选，并附规则标题、修订的 CFR 部分、DATES 段落及《联邦公报》记录中的逐字引文。按文件编号获取某条规则的完整信息，包括发布日期和 federalregister.gov 链接。列出各机构及其规则数量、最早和最晚生效日期。查找修订指定 CFR 标题与部分的规则，例如 49 CFR 192。核验关于规则生效日期、机构或所修订 CFR 部分的说法是否与存储记录和引文一致。
适用场景
适合需要了解某时间段内生效的美国联邦规则、哪些规则涉及特定 CFR 部分，或核实某项生效日期、机构信息是否准确时使用。适用于合规、监管与政策研究，且答案可追溯到《联邦公报》。
运行要求
需连接 referencesource.org 的远程 streamable-HTTP 端点；未声明需要账户、API 密钥或环境变量。README 另述可通过 npx 运行 npm 包作为 stdio 桥接，需要 Node 18 或更高版本。需能访问该端点。
安装前请注意
仅提供只读查询，不会写入、发送或删除数据。核验结论只说明所存来源的表述，不代表现实世界中即为事实；not_found 仅表示该登记册中没有此项。它只检索自身已发布的记录，无法核验任意网页。适用标准服务器请求日志。

安装

在 SourceWeft 中

  1. 打开 控制台中的 US federal rules taking effect，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

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.

输入参数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.

输入参数document_number必填

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".

输入参数query

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.

输入参数fromlimitcfr_part必填

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.
