"Proton VPN" matching MCP servers:

Enables agents to purchase VPN access by locally signing and broadcasting x402 USDC payments on Solana or EVM, then fulfilling payments to obtain and save credentials.

AgentPay VN — an MCP server that lets your AI agent collect real (fiat) payments over VietQR

Enables MCP clients like Claude Code, Claude Desktop, or Cursor to read and manage Remnawave 3.x VPN panel resources — users, nodes, hosts, config profiles, squads, subscription templates, billing, and HWID devices — through the panel's REST API, with contract-driven tool schemas, numeric user IDs, multi-panel config lookup, and an optional readonly mode.

Enables AI agents to build and parse VietQR payments, convert old 63-province addresses to the 34-province structure, validate tax IDs and e-invoices, turn money amounts into Vietnamese words, and convert between solar and lunar calendar dates. All tools run offline with bundled data, returning structured ok/error results.
