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.

  const r = spawn(ps.exe, ["-NoProfile", "-NonInteractive", "-ExecutionPolicy", "Bypass", "-Command", ACL_SCRIPT], {

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.

            (bool ok, bytes memory r) = address(this).delegatecall(data[i]);

This one needs environment variables set before it will start: PRIORS_KEY (Private key of a dedicated agent wallet on Robinhood Chain; without it (or PRIORS_KEY_FILE) only the read-only tools work), PRIORS_KEY_FILE (Absolute path (or ~/) of a file holding the agent wallet's key, read only when nobody but the user can read it; instead of PRIORS_KEY), PRIORS_AGENT_ID (The wallet's Priors (ERC-8004) agent id, when it cannot be looked up), PRIORS_MAX_PRICE_USD (Most one x402 call may cost (default 1.00)), PRIORS_MAX_SPEND_USD (Most x402 payments may total while the server runs (default 5)), PRIORS_MAX_BORROW_USD (Most one loan may be (default 25)), PRIORS_MAX_SPEND_DAY_USD (Most x402 payments may total per UTC day for the agent, across restarts (needs PRIORS_AGENT_ID)), PRIORS_MAX_BORROW_DAY_USD (Most the agent may borrow per UTC day, across restarts (needs PRIORS_AGENT_ID; 0 turns borrowing off)), PRIORS_PAY_HOSTS (Comma-separated exact hosts pay_url may pay; any other URL is refused before a request).
