Tools

• create_context ~546 tokens
  Share text, markdown, code, or HTML as an auto-expiring ctxt.io link. For visual output (styled reports, tables, charts, diagrams) prefer format=html with self-contained HTML: inline CSS and inline SVG render fully; <script> is stripped server-side and JavaScript never runs, so keep it static. Free
• delete_context Deletes data · ~156 tokens
  Delete a ctxt.io link you created. Requires the delete_token returned by create_context. Immediately removes public access and requests backing-storage deletion. Destructive and not undoable — confirm with the user before calling.
• read_context ~163 tokens
  Fetch the content of an existing ctxt.io link. Accepts a full ctxt.io URL, a /3/<code> path, or a bare code. Password-protected links need the password argument.
