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.

    Description, as the server wrote it
    Use this when the user asks about a Japanese grammar pattern or particle (〜てもいい, ために, ば vs たら, は and が), what it means, how it is used, an example of it, or how to say something with a pattern. Searches the site’s 828 grammar points (N5–N1) by the pattern in Japanese or romaji, or by its meaning in the user’s language. Each result has the pattern, JLPT level, meaning in the user’s language, an example sentence with translation, a link to the site’s free recording of the example where one exists, and the grammar page; plus the site’s course lessons whose titles match, with links and whether each is free.

    • The name "list_courses" says "list": a word for reading.
    Description, as the server wrote it
    Use this when the user asks how to study Japanese or prepare for a JLPT level with Japanese Skills · 言の葉, what the site has, or what is free. Lists the free study library (counts and links), the JLPT practice levels (Starter and N5 free; N4–N2 with a subscription or pass), and the 15 courses with their level, number of lessons, how many are free and their links. With course, lists that course’s lessons (title, free or not, link). States the published prices only as the pricing page does, with its link.

    • The name "lookup_kanji" says "lookup": a word for reading.
    Description, as the server wrote it
    Use this when the user asks about a kanji (a Chinese character used in Japanese): which JLPT words use it and how it is read in them, at which JLPT level it first appears, or where to learn it. For each kanji given (up to five), lists the words in the site’s JLPT word list that contain it, easiest level first, with reading, level and meaning in the user’s language; how many words use it and the lowest level among them; and the site’s kanji lessons that teach it (title, link, free or subscription). Gives no on’yomi/kun’yomi table or stroke order: the readings are those of the words.

    Why it is in this group

    • The name "lookup_word" says "lookup": a word for reading.
    Description, as the server wrote it
    Use this when the user asks about a Japanese word: what it means, how to read or pronounce it, its pitch accent, whether it is a godan or ichidan verb, how to conjugate it (te-form, past, polite, potential…), or how to say something in Japanese. Searches the 9,040 JLPT words (N5–N1) of Japanese Skills · 言の葉 by the word in kanji or kana (食べる, たべる), romaji (taberu), or a meaning in English, Chinese or Korean (eat, 吃, 먹다). Each result has the reading, JLPT level, the meaning in the user’s language, the pitch accent (accent number, type and H/L pattern), the word class and conjugation table where the site has one, an example sentence with its translation where the site has one, links to the site’s recordings in two voices where a free one exists, and the word’s page. Shows a word card in chats that display app UI. Returns no results when the word is not in the list. Not for translating whole sentences.

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

Changes to its tool definitions and to its remote endpoint, newest first.

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

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__japaneseskills__lookup_word",
      "mcp__japaneseskills__lookup_kanji",

      "mcp__japaneseskills__list_courses"
    ],
    "ask": [],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as japaneseskills. Review it before you use it.

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
