# Letter.md works with AI through MCP

Letter.md can now be connected to AI tools without turning your documents into a separate copy or export.

## What changed

- Connect ChatGPT, Codex, Cursor, and other MCP clients through secure OAuth.
- Find and read the latest Markdown in your Letter.md workspace.
- Create new documents, open them in Letter.md, and prepare reviewable suggestions.
- Built-in authoring and review skills help compatible clients choose documents carefully and keep edits traceable.

Publishing remains an explicit action in Letter.md. Connecting an AI client does not make a document public.
