Anlyon alternative
3 of these tools change something. Run those 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.

Can't be undone 1Claude Code: ask
publish_boardPublishes a board and returns a link that opens it in the user's browser.Reads text others writeCan send data outNo findings
Why it is in this group
- The name "publish_board" says "publish": a word for a change that another call does not undo.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe name "publish_board" says "publish": it sends or publishes something to other people.
Description, as the server wrote it Publishes a board and returns a link that opens it in the user's browser. Call check_board first. A board with errors is not published: the problems come back instead. With narration_language, the :::say blocks are voiced, so that the presentation plays with a voice. Give the link to the user exactly as returned.

Changes things 2Claude Code: ask
add_to_boardAdds board text to the board the teacher has open, behind a live link (.../live/<id>).No findings
Why it is in this group
- The name "add_to_board" says "add": a word for a change.
Description, as the server wrote it Adds board text to the board the teacher has open, behind a live link (.../live/<id>). place "current_page": put it under what is on the page the teacher is on (write ONE page: the next step, a hint, a drawing). place "new_pages": add your pages after the last page (exercises, answers, a new topic). Call check_board first: a text with errors is not added. Nothing on the board is changed or removed; the teacher can undo the addition.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: false
- openWorldHint: false
check_boardChecks a board text without publishing it.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it Checks a board text without publishing it. Returns what the board understood, page by page, and every problem with its line and how to fix it. Fix every ERROR, then call check_board again. When there are no errors, call publish_board.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

get_board_formatReturns the Notematics text format with a complete example.No findings
Why it is in this group
- The name "get_board_format" says "get": a word for reading.
Description, as the server wrote it Returns the Notematics text format with a complete example. Read it before writing a board, unless you already have it.

Why it is in this group
- The name "get_voices" says "get": a word for reading.
Description, as the server wrote it Lists the voices this Notematics site can voice narration with now, language by language: each voice's id, name and whether it is a man's or a woman's, and the default voice of the language. A language that is not listed cannot be voiced now. Give a voice to publish_board as narration_voice.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
read_boardReads the board behind a Notematics link the user gave you and returns it as board text, in the same format you write.No findings
Why it is in this group
- The name "read_board" says "read": a word for reading.
Description, as the server wrote it Reads the board behind a Notematics link the user gave you and returns it as board text, in the same format you write. Ink, images, widgets and the audio of narration cannot be written as text and are listed as left out (narration text is kept, as :::say; the wire man or girl as :::companion and the moods as :::mood; how steps appear as :::show; the marks drawn over what is written as :::strike, :::circle… lines; the look of words as spans). For a live link it also says which page the teacher is on.

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.
- Reads private data0
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write1
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out1
- 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.
{
"permissions": {
"allow": [
"mcp__notematics__get_board_format",
"mcp__notematics__get_voices",
"mcp__notematics__read_board"
],
"ask": [
"mcp__notematics__check_board",
"mcp__notematics__publish_board",
"mcp__notematics__add_to_board"
],
"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 notematics. Review it before you use it.

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