Looks things up and changes nothing. Claude Code: allow.

### `get_product`

- The name "get_product" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full detail on one product by catalog id: price (USD + USDC atomic), category, description, bundle contents, cover, and — for buyable products — a live payment block fetched from the real x402 402 challenge (network, USDC contract, amount, pay-to wallet).
```

### `how_to_buy`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the precise, step-by-step x402 payment sequence to buy a product: live network/USDC-contract/amount/pay-to values from the real 402 challenge, assembled into ordered steps.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List categories present in the live catalog with product counts. Categories are heuristically derived from id/title (the catalog API has no category field of its own).
```

### `search_products`

- The name "search_products" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search Lawrence Lanoff's live digital-product catalog by keyword, price ceiling, and/or category. Returns id, title, price_usd, category, buyable_via_x402, x402_url (tagged ?src=mcp-remote for attribution — use this exact URL), and cover.
```
