What the code does

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Deletes files or strips permissions packages/contracts/deploy-mainnet.ts:114
      `rm -rf ${LIBS.map((l) => l.dir).join(" ")}`,
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.

  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 things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch Arcade1v1 and you get told the day something new turns up.

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.

Optional settings from the registry entry, left out of the block above: 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)), ARCADE_MODEL (AI model this server declares when it sits at an Aleph table, e.g. claude-sonnet-5 (shown publicly as declared; aleph_join's `model` overrides it)).

Arcade1v1 — questions

Answers built from our own checks of this server.

Why is there no uptime for Arcade1v1?
Arcade1v1 runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @arcade1v1/mcp was installed 75 times last week.
How do I connect Arcade1v1?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @arcade1v1/mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Arcade1v1?
The npm package @arcade1v1/mcp was installed 75 times in the last week. Week over week that is -24%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Arcade1v1 open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
