Manage persistent dev servers, APIs, and other local processes on a port using macOS LaunchAgents. Use when starting, stopping, restarting, inspecting, or troubleshooting local servers that should survive shell exit and restart after crashes.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Persistent localhost servers (macOS launchd) One script does everything. Resolve `scripts/persistent-localhost.sh` relative to this `SKILL.md`, never from the current directory. ## Workflow 1. Check what already exists: ```bash scripts/persistent-localhost.sh list ``` 2. Start the server. `--name` is the handle. `--port` enables readiness checks and duplicate handling. `--dir` defaults to the current directory. ```bash scripts/persistent-localhost.sh start --name myproj --port 5111 --cmd "./bin/serve" ``` The command returns only after the port is listening, or fails with the last 20 log lines. Report the printed `URL=` to the user. 3. Inspect, restart, read logs, stop: ```bash scripts/persistent-localhost.sh status myproj scripts/persistent-localhost.sh restart myproj # after editing code that has no reloader scripts/persistent-localhost.sh logs myproj 100 scripts/persistent-localhost.sh stop myproj ``` ## Hot reload …

How to install
mdr add davidondrej/skills/persistent-localhost@sha256:bc6e550d20b4867fThe line at the top of this page pins the label git:20260925.cb72780, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
