Capabilities

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.

  try { return JSON.parse(fs.readFileSync(path.join(DIR, rel), "utf8")); }
    execFile(GH_BIN, argv, { timeout: timeoutMs, maxBuffer: 8 * 1024 * 1024 }, (err, stdout) => {
      document.getElementById("tablewrap").innerHTML = html;
Reads files and sends them to the network offchain/arena-entries.js:54
    for (const name of fs.readdirSync(FLOOR_DIR)) {

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

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.
