What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • open

    Create {text, filename}, resume {document}, open a Note {document, note}, create one {document, note:"new", text, title} (title only there), or import a host file {file}. Returns revision and whole text when it fits a page; otherwise a document map. A browser code goes to show {t

  • read

    Read exact text, a heading/fence map (as:"outline") or a PNG (as:"image") of the page or of the named block, heading or lines; a drawing's block gives it at full detail, even while it is open in Draw. query finds lines here; search lists Notes. Continue next_cursor with cursor al

  • edit

    Apply unique exact-text changes atomically as one undoable act (act is its id string), rename with filename, or set Note fields with note. At a moved numeric revision, literal edits apply if untouched since; whole-document replacement needs the current revision. A conflict return

  • undo

    Undo one act or one turn (act or turn_id, not both), preserving later work.

  • show

    Present work or ask the person. An omitted target is inferred from its fields. A 4-letter browser code pairs that editor (target:"pair"); a connected workspace's owner first approves at owner_approval_url, then the person chooses ALLOW. pairing.status: none, code_shown, owner_app

  • export

    to:"file" (default) delivers markdown, html, page, txt, docx or pdf (html is the whole editor with the document inside, editable offline); to:"save" saves to the bound destination; to:"clipboard" copies a passage as plain, markdown, formatted or complete. to:"sync" alone syncs th

Common questions

Is Rapier - Markdown Editor & Art safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.55) reached the registry 3 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
