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 belowshutdown→ see Shutdown belowupdate→mug update(forces full refresh — normally auto-runs every 4h)deploy→mug deployclone→ see Clone belowworkspaces→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 (requirescloudflaredinstalled)
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.
