Model Context Protocol (MCP) server for Shieldz. Lets an AI agent (Claude, etc.) accept non-custodial crypto payments.

Funds always settle to the wallet address you provide. Shieldz never holds your keys.

Keyless tools (no account, no API key)

Give a destination wallet address and start accepting crypto in one call:

• create_payment_link — a one-time payment link (shareable URL + embeddable button + QR). Args: address, amount_usd, optional chain (default base), asset (default USDC), memo, email.
• create_tip_jar — a reusable "pay what you want" page; the payer chooses the amount. Args: address, optional chain, asset, title, suggested_amounts_usd, slug, email.
• get_account_status — look up settlement details, tip jars, totals, and invoices by manage_token.

These work with zero configuration. Pass an optional email so the owner can claim a full dashboard later via magic link.

Remote (no install) — point any MCP client at the hosted server:

{ "mcpServers": { "shieldz": { "url": "https://shieldz.cash/mcp" } } }

Local (stdio) — run via npx:

{
  "mcpServers": {
    "shieldz": {
      "command": "npx",
      "args": ["-y", "@shieldz/mcp"]
    }
  }
}

API-key tools (full merchant account)

Set SHIELDZ_API_KEY to additionally enable richer invoice management: create_invoice, get_invoice, list_invoices.

{
  "mcpServers": {
    "shieldz": {
      "command": "npx",
      "args": ["-y", "@shieldz/mcp"],
      "env": { "SHIELDZ_API_KEY": "sk_live_…" }
    }
  }
}

Get an API key from your merchant dashboard → Developers.

Environment

• SHIELDZ_API_KEY (optional) — enables the invoice tools. Omit for keyless mode.
• SHIELDZ_BASE_URL (optional) — defaults to https://shieldz.cash.
