MCP Server: app.openkrill/rules

The MCP server app.openkrill/rules provides access to the underlying rules content. Its description indicates that the intended interaction is to “Read the rule itself instead of a summary of it,” meaning the server focuses on retrieving the full rule text rather than condensed explanations.

🛠️ Key Features

Exposes rule content directly for reading

🚀 Use Cases

Retrieve a specific rule’s full text for review
Use rule text as a reference instead of relying on summaries

⚡ Developer Benefits

Clear access pattern geared toward full rule retrieval

⚠️ Limitations

No additional capabilities, topics, or tool count are provided in the available source data

Captured live from the server via tools/list.

get_cfr_section

Read an eCFR section (FDA, OSHA, EPA). Use this when the user asks what a specific US federal regulation says, including an FDA, OSHA, EPA, SEC, FTC or FAA section of the eCFR, for example "what does 21 CFR 11.10 say?", "read 29 CFR 1910.134" or "show me 17 CFR 240.10b-5". Pass the CFR title number and the section number. Returns the current text, heading, statutory authority and amendment history of the section, the date the eCFR is up to date as of and a link to it. A very long section is cut and flagged. This is general information, not legal advice. Do not use it to find a regulation by topic (use search_cfr), for statutes, state law or court decisions, or to decide whether someone complies.

Parameters2

title	integer	required	CFR title number, 1 to 50: for example 21 is Food and Drugs, 29 Labor, 17 Securities, 40 Environment, 14 Aeronautics.
section	string	required	Section number as written in the citation, without the section sign: "11.10", "240.10b-5" or "1910.134".

search_cfr

Use this when the user asks which US federal regulations or compliance rules cover a topic, including an OSHA, EPA or FDA rule, for example "which regulations mention respirator fit testing?", "find the rules on electronic signatures in title 21" or "where does the CFR define small business?". Pass the words to find and, if known, the CFR title to search in. Returns the best matching sections with citation, heading, an excerpt, the agency and a link; use get_cfr_section to read one in full. This is general information, not legal advice. Do not use it for recent rulemaking news (use search_federal_register), statutes, state law or court decisions.

Parameters3

query	string	required	Words to find in the current regulations, for example 'electronic signatures' or 'respirator fit testing'.
title	integer	optional	Only search this CFR title. Leave out to search all titles.

search_federal_register

Use this when the user asks what federal agencies have published, proposed or announced, including a rulemaking, for example "what has the FDA proposed on food dyes?", "find final rules on noncompete agreements" or "which executive orders mention AI this year?". Pass the words to find and optionally the document type (rule, proposed_rule, notice, presidential_document) and a publication date range. Returns each document's title, type, agencies, publication date, abstract, effective date, comment deadline, the CFR parts it changes and a link. This is general information, not legal advice. Do not use it to read the current text of a regulation (use get_cfr_section), or for state law, bills, court decisions or non-US rules.

Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Parameters3
