ShieldZCash tools (4, 3 write)

write = sends, deletes, buys or posts
  • create_payment_linkwrite actionFree

    Create a one-time crypto payment link with ZERO setup, no account, no API key. Give a destination wallet address and an amount; get back a shareable pay_url, an embeddable button, and a manage_url. Non-custodial: funds settle directly to the address you provide.

  • create_tip_jarwrite actionFree

    Create a reusable 'pay what you want' tip jar with ZERO setup. The payer chooses the amount. Returns a shareable /tip url, an embeddable button, and a manage_url. Idempotent per wallet address. Non-custodial.

  • create_unlockwrite actionFree

    Create a keyless pay-to-unlock page: sell a file link, license key, or secret text (up to 100,000 chars). The buyer pays the set USD price in crypto straight to the given wallet, then the payload is revealed on their paid confirmation, never before. To deliver an actual file (PDF/zip/etc, 10 MB) use the multipart HTTP API at /api/v1/unlocks instead. Non-custodial, no account, no API key. IMPORTANT: the acceptable-use policy forbids adult, illegal, or non-consensual content; confirm this with your principal and pass aup_accepted=true, otherwise the call fails.

  • get_account_statusFree

    Look up a keyless Shieldz account by its manage_token (returned when you create a payment link or tip jar). Returns settlement details, tip jars, totals (paid/pending), and the invoice list as structured JSON.

What the publisher says

From the ShieldZCash repository's README, as published. We do not edit it. Read it on GitHub

@shieldz/mcp

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

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:

  • createpaymentlink — a one-time payment link (shareable URL + embeddable button + QR). Args: address, amount_usd, optional chain (default base), asset (default USDC), memo, email.
  • createtipjar — a reusable "pay what you want" page; the payer chooses the amount. Args: address, optional chain, asset, title, suggestedamountsusd, slug, email.
  • createunlock — sell a digital product: a pay-to-unlock page for a file link, license key, or secret text (up to 100k chars). The buyer pays and the payload is revealed on their paid confirmation, automatically. Args: address, priceusd, payload, aup_accepted, optional title, description, chain, asset, email. (To deliver an uploaded file up to 10 MB, post multipart to /api/v1/unlocks.)
  • getaccountstatus — 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 SHIELDZAPIKEY to additionally enable richer invoice management: createinvoice, getinvoice, 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

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