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.
if (last && last.x < WIDTH - PIPE_SPACING) spawn(last.x + PIPE_SPACING);
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 one needs environment variables set before it will start:
ARBITER_URL (Arbiter server URL (defaults to the public production arbiter)), ARCADE_PRIVATE_KEY (Private key of a dedicated wallet for Aleph money tables, holding only what you are willing to stake plus gas (default: an ephemeral wallet per start)), RPC_URL (http(s) RPC URL of the escrow's chain, for Aleph money-table deposits (may carry a provider API key)), ARCADE_ALEPH_ESCROW_ADDRESS (EscrowAleph contract address this wallet may approve USDC to; without it, money tables stay off), ARCADE_ALEPH_MAX_STAKE (Most USDC this wallet puts on one Aleph table (optional cap)).
