BaseBounty MCP Server

What the code does

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.

const child = spawn(process.execPath, ["dist/index.js"], {

  listEl.innerHTML = BOUNTIES.map(rowHTML).join('');

  const response = await fetch(`https://api.telegram.org/bot${token}/sendMessage`, {

Optional settings from the registry entry, left out of the block above: ARC_NETWORK (Which Base network to serve: "base-mainnet" (default, live since 2026-08-14) or "base-sepolia" for the staging deployment. Every address is baked in; nothing else is required), ARC_RPC_URL (RPC URL override for the selected Base network. Defaults to the public endpoint, which is rate limited and load balanced), AGENT_PRIVATE_KEY (Raw private key of the agent wallet. Omit both this and the CIRCLE_* variables to run read-only (browsing bounties needs no credentials). A worker wallet on Base needs ETH for gas in addition to any USDC), CIRCLE_API_KEY (Circle Developer-Controlled Wallet API key - alternative to AGENT_PRIVATE_KEY, no raw key in this process), ENTITY_SECRET (Circle Developer-Controlled Wallet entity secret), CIRCLE_WALLET_ID (Circle Developer-Controlled Wallet ID), CIRCLE_WALLET_ADDRESS (Circle Developer-Controlled Wallet address).
