## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `payment_info`

- The name "payment_info" says "payment": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Return the x402 payment requirements for one categorization call.

Meant for an agent that holds no API key: gives network, asset, recipient
address and amount as JSON, so the payment authorization can be signed
before calling `categorize_product`. Free of charge.
```

## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `categorize_product`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Map a free-text product description to a marketplace category path.

Walks the taxonomy of the target marketplace one level at a time and
returns the full path: one match per level, from the broadest category down
to the most specific one, each with the reason it was picked. Use it to
assign a listing category to a product you only have prose for.

The last match carries `truncated: true` when the per-request token budget
stopped the descent before a leaf. Every successful call is billed: with no
`X-API-Key` header and no x402 payment proof the tool answers with the
payment requirements instead of a result.
```

## Only reads (1)

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

### `list_stores`

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

Description, as the server wrote it:

```untrusted-server-text
List the marketplaces whose taxonomies are loaded, as `store_id` values.

These are the only accepted values for the `store_id` argument of
`categorize_product`. Free of charge on purpose: without it an agent would
have to pay for a failed call to discover them.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `mcb`:

```json
{
  "permissions": {
    "allow": [
      "mcp__mcb__list_stores"
    ],
    "ask": [
      "mcp__mcb__categorize_product",
      "mcp__mcb__payment_info"
    ],
    "deny": []
  }
}
```
