PrivadoVPN x402 Payer MCP server

@privadovpn/x402-mcp

Local stdio MCP server that signs and broadcasts x402 USDC payments (Solana, EVM) to buy PrivadoVPN access.

Security model

This server signs payments locally and never transmits your private key anywhere.

• SOLANAPRIVATEKEY and EVMPRIVATEKEY are read from local process environment variables. They are used only to sign transactions in-process and are never sent over the network or written to disk by this server.
• The only data that leaves the machine is a signed payment authorization (EVM EIP-3009) or a broadcast transaction signature (Solana), sent to X402BASEURL to fulfill a purchase.
• Use a dedicated, low-balance wallet for this server — never point it at a primary or high-balance wallet.
• wallet_status returns configured addresses and network selection only. It never returns private keys or any secret material.
• Credentials returned after a successful purchase are written only to ~/.privado/ on your local machine.
