What the sources write about this name
| 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. |
| 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). |
| MCP server 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. |
| MCP server 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. |
| MCP server 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 |
| MCP server 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. |
| MCP server 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. |
| MCP server in namespace io.github | Private key of the paying wallet (USDC on Base mainnet). Signs x402 payment authorizations locally. |
| MCP server in namespace io.github | Base EOA private key (hex, 0x-prefixed) with USDC for signing x402 payments |
