Nothing serious here today

Today is the operative word: we check Notematics every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

board

add_to_board

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.

check_board

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.

get_board_format

Returns the Notematics text format with a complete example. Read it before writing a board, unless you already have it.

read_board

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; the points, figures and texts of a graph as its lines; a built-in board theme as :::theme). For a live link it also says which page the teacher is on.

publish

publish_board

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.

voices

get_voices

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.

Notematics — questions

Answers built from our own checks of this server.

What can Notematics do?

It exposes 6 tools, read directly from the server on our last check. Among them: add_to_board, check_board, get_board_format, get_voices, publish_board, read_board. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Notematics working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 197 ms. The bar chart above shows every period we have measured.

How do I connect Notematics?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Notematics need an API key?

No. Notematics completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Notematics?

It answers our handshake in 197 ms on average, which is faster than 68% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
