## MCP tools (3)

### `create_payment_link` (~176 tokens)

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. Optionally pass an email so the owner can claim a full dashboard later.

Input parameters:

- `address` (string, required): Destination wallet; funds settle here. Shieldz never holds them.
- `amount_usd` (number, required): Amount in USD, e.g. 49 for $49.00
- `asset` (string): Defaults to USDC
- `chain` (string): Defaults to base
- `email` (string): Optional, lets the owner claim a dashboard later
- `memo` (string): Description shown on the checkout

### `create_tip_jar` (~217 tokens)

Create a reusable 'pay what you want' tip jar with ZERO setup, no account, no API key. The payer chooses the amount. Returns a shareable /tip url, an embeddable button, and a manage_url. Idempotent per wallet address: calling again updates the same tip jar. Non-custodial: funds settle directly to the address you provide.

Input parameters:

- `address` (string, required): Destination wallet; funds settle here. Shieldz never holds them.
- `asset` (string): Defaults to USDC
- `chain` (string): Defaults to base
- `description` (string)
- `email` (string): Optional, lets the owner claim a dashboard later
- `slug` (string): Optional custom URL slug; auto-generated if omitted
- `suggested_amounts_usd` (array): Preset amount buttons in USD, e.g. [3, 5, 10]
- `title` (string): Heading shown on the tip page, e.g. 'Buy me a coffee'

### `get_account_status` (~75 tokens)

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 full invoice list as structured JSON.

Input parameters:

- `manage_token` (string, required): The manage_token from create_payment_link / create_tip_jar
