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.

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.

This one needs environment variables set before it will start: AGENT_KEY (Hex private key of a wallet funded with USDC on Base, Solana, Polygon, Arbitrum, Monad, Celo, Avalanche, Sei, Optimism, Stellar or Algorand (or USDG on Robinhood Chain). Unset = proof-of-work mode (free pure-CPU tools).), AGENT402_BUDGET (Optional hard cap on total USDC spent per session (e.g. 1.00). Refused before any payment is signed.), AGENT402_MAX_PER_CALL (Optional max USD price for any single call (e.g. 0.01).), AGENT402_CREDITS_KEY (Prepaid card-credits key (a402_...) from https://agent402.tools/credits. With it set and no wallet key, every tool pays by card; the list price is debited only on a successful call.), SOLANA_AGENT_KEY (Optional base58 (or JSON byte-array) secret key of a Solana wallet funded with USDC on Solana.), AGENT402_NETWORKS (Optional: restrict and order the chains to pay on (e.g. "base,solana" or a CAIP-2 like eip155:4663).). The author declared them in the registry entry; get the values from the project itself.
