What the sources write about this name
| Agent Press Wire | Private key of YOUR OWN Base wallet holding USDC, used to pay per call via x402. Omit for quote-only mode. |
|---|---|
| Base Token Facts | Private key of a small x402 payer wallet holding a little USDC on Base (pays $0.002-$0.01 per call). Alternative: X402_PAYER_FILE. |
| OneSource MCP | EVM private key (64-char hex, 0x prefix optional) for automatic x402 USDC payments on Base |
| Package Intel | Optional. Leave unset to use the free tools. Setting it to the private key of a wallet funded with USDC on NETWORK additionally unlocks package_health and package_batch_health, paid per call. Use a dedicated low-balance wallet: this is a hot key that spends automatically. |
| SMX by Space Markets (testnet) | Optional. Your own Base Sepolia TEST wallet key holding Circle testnet USDC, used only by the paid tools ($0.01 testnet USDC per call, no real value). Never use a wallet with real funds. |
| com.walletbureau/mcp | Private key of a wallet holding USDC on Base to pay per call via x402. Optional; ignored when WALLETBUREAU_API_KEY is set. |
| com.wrapper-agency.parsedoc/parser | EVM wallet private key holding USDC on Base. When set, calls the paid endpoint at $0.02/page. If unset, uses the free demo (3/day). |
| x402-money-farm in namespace io.github | Private key of a Base wallet funded with USDC, used to pay per call. Without it only the free catalogue tool works. Gas is paid by the facilitator, so no ETH is needed. |
| x402-trust-mcp in namespace io.github | Optional Base wallet private key (with or without the 0x prefix). When set, the paid tools auto-pay over x402 up to X402_MAX_USD; otherwise they return a price quote. The free tools need no key. |
| ja-normalize in namespace io.github | Optional: Base wallet private key holding USDC for paid calls beyond the free daily quota |
| kr-dart-events in namespace io.github | EVM private key (0x...) of a wallet holding a few cents of USDC on Base. Used to sign x402 micro-payments. Gas is not needed. |
| nodeflare-mcp in namespace io.github | Optional EVM private key of a wallet holding USDC on Base/Polygon/Arbitrum — heavy methods are paid per call (~$0.001) via x402 |
| getdigitalcraft-mcp-render in namespace io.github | Private key of a wallet holding USDC on Base. Used locally to sign x402 payments; it never leaves your machine. Without it the server still starts and lists tools, but rendering is disabled. |
| genesis-agent-mcp in namespace io.github | Buyer x402 EIP-3009 signing key funded with USDC on Base. Never commit it. |
| automatedrcm-billing-mcp in namespace io.github | Optional. Private key of a wallet holding a little USDC on Base mainnet — enables the paid tools ($0.01–$1.50/call, gasless EIP-3009). Free tools (catalog, free_samples) work without it. Use a dedicated low-balance wallet. |
| navi-x402-mcp in namespace io.github | Private key of the paying wallet (USDC on Base mainnet). Signs x402 payment authorizations locally. |
| x402-mcp in namespace io.github | Base EOA private key (hex, 0x-prefixed) with USDC for signing x402 payments |
| x402 Trinity | Private key of the wallet that pays. Use a dedicated wallet holding only what you would accept losing. The server refuses to start without it. |
