Mug

Mug CLI

Run a Mug developer workflow command.

Input

Command: $ARGUMENTS

Dispatch

Run the matching CLI command in the workspace root:

• dev → see Dev Server below
• shutdown → see Shutdown below
• update → mug update (forces full refresh — normally auto-runs every 4h)
• deploy → mug deploy
• clone → see Clone below
• workspaces → mug workspaces

If no argument or unrecognized argument, show available commands and ask which to run.

Dev Server

The dev server hot-reloads file changes automatically — editing connectors, workflows, agents, surfaces, or config files takes effect immediately without a restart. Only restart after a CLI update (mug update).

Check if a dev server is already running by looking for the PID file:

cat .mug/dev.pid 2>/dev/null

If a dev server is already running, you're done — it will pick up your changes. Only start a new one if no server is running:

mug dev

Run this command in the background — it's a long-running process.

Options:

• mug dev --port <port> — pin to a specific port (default: auto-detect from 8787)
• mug dev --tunnel — expose via Cloudflare Quick Tunnel (requires cloudflared installed)

The dev server auto-detects free ports, so multiple workspaces can run simultaneously.

Shutdown

Gracefully stop the running dev server. Writes back database changes and cleans up.

mug shutdown

This reads .mug/dev.pid and sends SIGTERM to the dev server process.

Clone

Clone an existing workspace from Mug cloud to the local machine. Creates a new directory, scaffolds workspace structure, and connects it to the cloud workspace.

mug clone                 # shows workspace picker if you have multiple
mug clone acme            # clone by name, subdomain, or ID

Files and databases stay remote — use mug pull --all to download locally if needed. Requires mug login first.
