io.github.stevemilton/buyforme-mcp (MCP server)

BuyForMe is an MCP server alias (io.github.stevemilton/buyforme-mcp) that provides a “buy for me” tool. It pays any x402-priced URL in USD or EUR via ArisPay delegated custody, so private keys are not kept in the client process. It is an alias of @arispay/payagent-mcp.

buyforme-mcp

MCP server alias for @arispay/payagent-mcp.

Configure your MCP-capable client (Claude Desktop, Cursor, Windsurf, …) to spawn buyforme-mcp and the model gets a "buy for me" tool that pays any x402-priced URL via ArisPay delegated custody — no private keys in your process.

Claude Desktop / Cursor / Windsurf config

jsonc

{
  "mcpServers": {
    "buyforme": {
      "command": "npx",
      "args": ["-y", "buyforme-mcp"]
    }
  }
}

That's identical to using @arispay/payagent-mcp directly — the proxy spawns the upstream server with stdio inherited, so the JSON-RPC stream flows through without inspection or modification.

What you get inside the model

The same MCP tools the upstream server exposes — pay_api, check_wallet, create_agent, fund_agent, get_balance, list_agents — backed by ArisPay's delegated-custody wallets: Coinbase CDP holds the signing key, ArisPay enforces per-tx, daily, monthly, and allowed-domain limits server-side, and signs on the agent's behalf when it hits an HTTP 402.

For the full tool surface, see the @arispay/payagent-mcp README.

Configuration

Environment variables

ARISPAY_API_KEYsecret

Optional. ArisPay developer API key (ap_live_… / ap_test_…). The create_user tool can self-provision one from just an email.

PAYAGENT_PRIVATE_KEYsecret

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.
