NoteOperator

NoteOperator is a focused Markdown workspace with a built-in MCP server for humans and AI agents. Write notes in Markdown with autosave, formatting tools, and PDF export. Share documents through public links with no account required for readers. Connect Claude, Cursor, Windsurf, and other compatible clients through scoped API keys so AI agents can access only the permissions you allow. It is free, requires no credit card, and supports sign-in with Google or GitHub.
