Expose, preview, protect with x402 payments or sign-in, or keep a local web app, static site, HTTP route set, or explicitly requested TCP/UDP service reachable through Portal, then verify the public endpoint and report its lifecycle. This is the app side of Portal, the same flow as the quick-start form on a relay website (install, run one portal expose command built from the app settings, open the public URL). Use when the user asks to deploy, publish, share, tunnel, expose, or connect a local…
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
# Expose an App with Portal Portal publishes a service that is already running on the user's machine. It does not build the app or move it to a cloud host. Treat a successful tunnel as dependent on both the local app and the Portal process or agent remaining available. This is the app side of Portal: every relay website offers the same three steps (paste what to share, run one install-and-expose command built from the app settings, open the public URL), and this skill performs those steps for the app with verification around them. Any other program that reaches the published URL needs nothing from Portal. Run the workflow in order. Open a reference only when that branch is taken: `references/x402.md` for a paid route, `references/application-auth.md` when only chosen people may open the URL (a credential link, wallet, OIDC, SAML, or email link sign-in), `references/safety-and-verification.md` for an authenticated, sensitive/high-risk, or non-HTTP service, `references/game-hosting.md` for a game server, `references/agent-backends.md` for a web UI or API that controls coding agents or a shell (herdr web clients such as Ovis, agent dashboards, browser terminals)… …

How to install
mdr add gosuda/portal-tunnel/portal-expose@sha256:f62172f24f8ee1f9The line at the top of this page pins the label git:20261108.8ccc40c, 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.
