easymd

Google Docs for markdown — except the file on disk stays canonical.

Collaborate on CLAUDE.md, AGENTS.md, or any .md file in real time. The document on screen is the actual file in your repo. No import/export round-trip, no copy-paste tax.

Web app (landing + demo)

Professional landing page with token savings messaging, Clerk auth for signups, and a protected live demo at /demo.

cd web
cp .env.example .env.local   # add Clerk keys from dashboard.clerk.com
npm install
npm run dev                  # Next.js + collab WebSocket server

Open http://localhost:3000 → Sign up → Live collaborative editor.

Token savings (why markdown for AI)

Converting PDFs, Word/DOCX, or HTML to clean .md cuts token usage dramatically:

| Format | Typical savings | |--------|-----------------| | Raw HTML | 75–90% | | Word / DOCX | 50–70% | | Text-based PDF | 40–65% |

Markdown strips hidden formatting metadata while keeping structure agents need — then reference @CLAUDE.md on demand instead of pasting every prompt.

CLI (local file editing)

npm install
npm run build
easymd open CLAUDE.md

Share the URL with a teammate. Edits sync live via CRDT. Changes land straight back to the file on disk and into git.

CLI auto-sync (push every .md into your account)

Sign in once, then have every markdown file in your repo sync into your easymd account automatically — so anything you or an AI agent writes to disk shows up in the dashboard and is editable live.

npx easymd-cli login          # opens your browser, sign in with Clerk, authorize this machine
npx easymd-cli auto on        # background watcher: every new/changed .md syncs to your account
npx easymd-cli auto status    # check it's running
npx easymd-cli auto off       # stop it

Other commands:

easymd sync ./docs        # one-shot push of all .md under a folder
easymd watch .            # foreground watcher (what `auto on` runs detached)
easymd whoami             # show the logged-in account
easymd logout             # remove credentials + stop auto-sync

Credentials live in ~/.easymd/credentials.json (a long-lived token bound to your Clerk user id — secrets stay on the server). Point the CLI at a self-hosted/production instance with EASYMD_URL=https://your-easymd.example.com.

AI agents (MCP)

easymd ships an MCP server so AI agents edit the same live documents humans do — changes sync in real time and persist to Supabase.

The easiest way is the CLI's bundled MCP server. It authenticates with your easymd login token (no API keys to paste) and works with any agent:

npm i -g easymd-cli
easymd login
easymd mcp-install        # registers it with Cursor + Claude Desktop
# Claude Code:  claude mcp add easymd -- easymd mcp

Or use add-mcp to register it across all detected agents (Cursor, Claude Desktop, VS Code, …) in one command:

npx add-mcp@latest --command easymd --args "mcp" --name easymd

Tools: list_documents, read_document, create_document, update_document, append_to_document. Docs an agent creates show up in your dashboard; edits an agent makes appear live in any open editor.

(The repo also has a server-side MCP at web/scripts/mcp-server.mjs — npm run mcp — which uses the service-role key directly; prefer the CLI version for end users.)

Why

AI agents made markdown load-bearing. AGENTS.md and CLAUDE.md are now the single source of truth for how your project works — but collaborating on them still means pull requests for engineers or copy-paste between Google Docs and your repo for everyone else.

easymd fixes the one painful shared file:

• Canonical file stays canonical — edit the real .md on disk, not a hosted copy
• Real-time multiplayer — live cursors, presence, CRDT conflict resolution
• CLI keeps it honest — easymd open path/to/file.md from your terminal
• Agents stay in the loop — the same file humans edit is what agents read and write
• Token-efficient by design — lightweight .md beats bloated DOCX/HTML/PDF for agent context

Project structure

web/                Next.js landing, Clerk auth, protected demo
bin/easymd.js       CLI entry point
src/server.js       Local HTTP + WebSocket server
src/file-sync.js    Disk ↔ Yjs sync
client/             CLI browser editor UI

Clerk setup

1. Create an app at dashboard.clerk.com
2. Copy keys into web/.env.local (see web/.env.example)
3. Enable Email + Google sign-in (recommended)
4. Set redirect URLs: after sign-in/sign-up → /demo
