A markdown editor with MCP

So AI agents can read and write your local markdown files. Markd.ly is one of the very few consumer editors that ships it — and this page is precise about exactly which platform each capability runs on, because vague AI claims are how people get burned.

What MCP does here

MCP lets an AI agent talk to Markd.ly's markdown context in a structured way — your documents become something an agent can operate on, not just text you paste into a chat box. In practice: an agent can pull in your notes, draft into your files, and work against your real local markdown instead of a copy living in someone's cloud.

The exact scope (read this before assuming)

  • MCP read access

    Available on the Mac build — agents can read your markdown context, included in the one-time purchase.

  • MCP write access: Mac only

    Letting an agent write into your files ships on the Mac direct-download build. MCP write is not on Windows — Windows tooling is rolling in across the 1.x series, and MCP write specifically is Mac-only at this contract. Do not assume Windows.

  • Not on mobile

    Mobile is a local editor with no MCP write.

Stating this plainly is the point: the value is real, but it is Mac-deepest, and the write capability is Mac-only today. Anyone who needs MCP write on Windows should not buy on the assumption it is there.

Why this matters

Most editors that talk about AI mean a chat panel that sees a copy of your text. MCP is different: it is structured access to your actual local files, so an agent's edits land in the .md on your disk — which is also where git, your other tools, and future-you will look. Because Markd.ly is files-on-disk with no proprietary container, there is no lock-in around the AI workflow either: the files an agent touches are just files.

The honest limits

  • MCP write is Mac only

    Restated because it is the single most important caveat on this page.

  • No sync

    The files an agent edits are local; Markd.ly does not sync them anywhere.

  • You own the risk surface

    Letting an agent write to files is powerful and you should treat it like any tool with write access — Markd.ly gives you the capability, not a safety net for an agent's mistakes.

  • Windows Pro is incomplete generally

    “Rolling across 1.x”; MCP write specifically is Mac.

Let your agents work on real files.

Native Mac & Windows editor. MCP read on Mac; MCP write is Mac-only today. One-time license: $19.99.
