Run the operations that matter as governed actions.
Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.
Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

fetchRead what an id from search names.No findings
Why it is in this group
- The name "fetch" says "fetch": a word for reading.
Description, as the server wrote it Read what an id from search names. A provision's id (labor-standards-act/art-36) returns it as Markdown: the Japanese text with each paragraph's English under it, every English line marked as the Ministry of Justice's translation, the Ministry's with a slip corrected, or machine translation; its address and URLs on every line; what it cites and what cites it; and its sources. A law's id (labor-standards-act) returns the law's overview — what it is for, who it applies to, how it is enforced — the texts held, and its outline, never its whole text. A japanlaw.org URL is accepted as an id too. A provision is read in the text in force unless asOf (a day) or version names another text held: an earlier one, or one an amendment not yet in force will leave.

Why it is in this group
- The name "get_amendments" says "get": a word for reading.
Description, as the server wrote it A law's amendments whose changes japanlaw.org holds: the amending Act (titles, law number), the day it takes effect, whether it is in force, not yet in force or since replaced (state), how many provisions it changes, adds and removes, and its revision key. With revision — {"law": "labor-standards-act", "revision": "20270401_508AC0000000060"} — every provision that amendment changes, its wording before and after in Japanese and English, and whose each English is (beforeEnglishWhose, afterEnglishWhose). A long one stops at a provision; continued.from, passed back as from with the same revision, goes on. An amendment e-Gov publishes no text for is named as such (comparedAcross, textPublished false): its changes are listed with the next amendment's and cannot be told apart from them — never describe them as its own. One whose changes are not held says so; never describe its changes from memory. version names the text an amendment leaves, for get_provision and fetch. Link each amendment by its url.

Description, as the server wrote it Every provision in the laws japanlaw.org holds that cites the given one — the other direction from what a statute says, which no official source publishes. Each with its law, designation, the words it cites with, an id for fetch and its url; link each one you name by its fromUrl.

Why it is in this group
- The name "get_definitions" says "get": a word for reading.
Description, as the server wrote it The words a law defines for itself (定義語): inside that law, and only as far as each definition reaches, the word means what the statute says, not what it means in everyday speech or in another law. For each, the statute's own words (statuteJa), its reading, its English and whose that is (englishWhose), a plain explanation by japanlaw.org (explanation, in lang), where it is defined (definedAt, url) and how far it reaches (scope, scopeLabel). With address — {"law": "labor-standards-act", "address": "art-36"} — the definitions that apply in that provision, because its text uses the word, and japanlaw.org's explanations of the words of Japanese law it uses (concepts: 施行, 政令, 附則…). Call it before explaining what a provision means. term narrows the answer to one word, in Japanese, its reading or its English. A law with many terms stops at one; continued.from, passed back as from with the same arguments, goes on. The text in force only.

Why it is in this group
- The name "get_law" says "get": a word for reading.
Description, as the server wrote it One law: titles, number, kind, when the text in force took effect, the texts held (versions: in force, not yet in force, no longer in force, each with the days it stands), how much of it has the Ministry's English, and this site's plain description of it — what it is for, who it applies to and who it does not, and on request (section) its exceptions and how it is enforced — each claim with the provisions it rests on (basis). Then its outline: by default the parts and chapters of the main text (編, 章); outline "articles" lists every article (for a very long law, its headings instead), and under (a heading's path, such as ch-4) lists everything under that heading. outlineUrl turns an outline path into its page.

get_provisionOne article, paragraph or item of a law, with everything under it.No findings
Why it is in this group
- The name "get_provision" says "get": a word for reading.
Description, as the server wrote it One article, paragraph or item of a law, with everything under it. Call it with law and address: {"law": "labor-standards-act", "address": "art-36"}, or {"law": "労働基準法", "address": "第三十二条の三第一項"}. For each paragraph and item, the Japanese text (textJa), its English (textEn) and whose that English is (englishWhose: ministry — the Ministry of Justice's translation; corrected — the Ministry's with a slip this site corrected; machine — this site's machine translation, not official), and its url. Also what the provision cites, the terms it defines, how many provisions cite it, and the official e-Gov page. A very long one — a big appended table, a 附則 of many articles — stops at a provision; continued.from, passed back as from with the same address, goes on from there. Shown to the reader as a card where the chat app can draw one. The text in force by default; asOf (a day) or version reads another text held — as it stood on a past day, or as an amendment not yet in force will leave it — and version says which text the answer is. Quoting it, link its url (the reader's page, with the English marked), not e-Gov's, and say whose English each quoted paragraph is.

Why it is in this group
- The name "list_laws" says "list": a word for reading.
Description, as the server wrote it Every law japanlaw.org holds: Japanese and English title, short names, kind (法律 Act, 政令 Cabinet Order, 省令 Ministerial Order…), law number, the date the text held took effect, number of articles, the share of paragraphs with English, and URLs; kinds counts them by kind. A law not in this list is not held, whatever its kind — a 条例 (a prefecture's or city's ordinance) included — so say so rather than quoting its text from memory.

searchSearch the Japanese statutes japanlaw.org holds, in force today.No findings
Why it is in this group
- The name "search" says "search": a word for reading.
Description, as the server wrote it Search the Japanese statutes japanlaw.org holds, in force today. A query with any Japanese in it searches the Japanese text (時間外労働, 有給休暇); one without searches the English shown for each provision, stemmed (overtime, paid leave). Results are laws whose title matches, then one result per matching article at its best-matching paragraph or item, best first; each has an id to pass to fetch (or pass its law and path to get_provision as law and address), the page's url, the Japanese and English designation (第三十六条第一項 / Article 36, paragraph (1)) and a snippet. terms lists words a law defines that match; concepts, words of Japanese law the site explains. Every word must be at least two characters. Only the laws list_laws names are searched; law searches one of them alone, its provisions and the terms it defines. When a law the reader names finds nothing, check list_laws: one not there is not held — say so rather than answering from memory.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
Exfil surface
Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.
No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write0
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out0
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
Findings
Matches of fixed checks, with the text they matched.
No check matched anything in these tool definitions. That is not a safety guarantee.
History

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.
