coolFTP

Let Claude deploy your site to your SFTP or FTP host, with undo and a check that it is actually live. One line in Claude Code:

/plugin install coolftp --marketplace anivdel/coolFTP

Then say "set up coolFTP for this project" and "deploy this". Only files whose content changed go up, the git commit is recorded next to the deploy, the site is fetched afterward to prove it answers, and "undo that" puts the previous version back, no git needed. Works with any host that speaks SFTP or FTP: Hostinger, HostGator, Bluehost, GoDaddy, any cPanel box, your own VPS. Free for 1 site and MIT; Pro ($49 once) unlocks unlimited sites. Website: coolftp.com.

The plugin, the coolftp CLI and the MCP server run on macOS, Linux and Windows with Node 18 or newer, and Cursor, Codex or any agent with a shell can drive them too. The Windows desktop app is an optional companion: with it open, you watch every agent call live and click to approve deletes, undos and rollbacks.

With the desktop app open, agents ask before they delete anything:

Why

Every FTP client assumes a human is clicking. coolFTP assumes a human is watching and an agent is doing.

• Hash-based deploys. A manifest on the server records the SHA-256 of every deployed file. Timestamps lie; hashes do not.
• Undo, no git needed. Every deploy moves the files it overwrites or deletes into a backup folder on the server first. coolftp undo puts them back, even from a dirty tree.
• Deploy history with git. Each deploy stores the commit, branch, dirty flag, message, byte count, which agent ran it, and whether the site verified live.
• One-command rollback. coolftp rollback restores the previous live commit through a temporary git worktree.
• Verification. Give a site its public URL and every deploy fetches the changed pages, compares static files byte for byte with what you uploaded, and exits non-zero when the site does not answer. coolftp verify does the same on demand.
• Live agent feed and approval dialog, in the desktop app. Deletes, --delete deploys, rollbacks and undos wait for your click while the app is open. Deploys show as a progress card, and a Windows notification tells you how they ended.
• Safety by default. Pinned SSH host keys, passwords encrypted with your Windows account, a first-deploy guard that refuses to delete files it never uploaded, changed files swapped into place rather than overwritten, sizes confirmed by the server, resumable deploys.

packages/core   shared TypeScript library: transports, sites, hash manifest, sync, deploy
packages/cli    `coolftp` command line + `coolftp mcp` MCP server for agents
packages/app    Electron desktop app (two-pane browser, transfer queue, live agent feed)
site/           landing page for coolftp.com
scripts/        build + end-to-end test

Install

The CLI and the MCP server run anywhere Node 18 or newer does: Windows, macOS, Linux, a headless box, CI.

npm i -g coolftp
coolftp --version

No install at all: npx coolftp ... runs the same thing.

The desktop app is Windows for now: the installer, a portable .exe and the Claude Desktop extension (.mcpb) are on the download page with their SHA-256s.

Build from source

npm install
npm run build
npm run app          # opens the desktop app
node packages/cli/dist/coolftp.js --help

To get a global coolftp command from this checkout instead of npm: cd packages/cli && npm link.

Add a server

# SFTP with your existing ~/.ssh key or the ssh-agent
coolftp site add coolftp.com --host coolftp.com --user deploy --root /var/www/html

# FTPS with a password (shared hosts)
coolftp site add oldhost --host ftp.oldhost.net --user me --protocol ftps --password '...' --root /public_html
