Hera Agent Unity runs on your own machine — the client starts it, so there is no endpoint to ping. 230 installs a week from npm. Last commit 29 Oct 2026.
Control and verify a live Unity Editor through a local, low-token MCP server.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
postinstall: node scripts/install.js
const result = spawnSync(binary, process.argv.slice(2), { stdio: "inherit" });
const binary = path.join(__dirname, "native", target.binaryName);
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.
proc = Process.Start(psi);
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
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.
