Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package buyforme-mcp
Claude Code 
claude mcp add buyforme-mcp -e 'ARISPAY_API_KEY=<your arispay_api_key>' -e 'PAYAGENT_PRIVATE_KEY=<your payagent_private_key>' -- npx -y buyforme-mcp@1.0.2
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "buyforme-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "buyforme-mcp@1.0.2"
            ],
            "env": {
                "ARISPAY_API_KEY": "<your arispay_api_key>",
                "PAYAGENT_PRIVATE_KEY": "<your payagent_private_key>"
            }
        }
    }
}

Environment variables

  • ARISPAY_API_KEY secret Optional. ArisPay developer API key (ap_live_… / ap_test_…). The create_user tool can self-provision one from just an email.
  • PAYAGENT_PRIVATE_KEY secret EVM private key for permissionless local signing (zero-signup mode): pay_api signs x402 payments with it directly — no ArisPay account needed. Generate one with `npx payagent wallet new`. Never sent to any server.
