Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

const dest = path.join(snapshotsDir, name);
if (platform === "darwin") execSync(`open "${url}"`, { stdio: "ignore" });
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
Today is the operative word: we check USRCP — User Context Protocol every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
USRCP_PASSPHRASE (Passphrase used to derive the ledger encryption key. Omit it if the passphrase is stored in the OS keychain via `usrcp keychain store`.).
