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

### `find_items`

- The name "find_items" says "find": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Finds exact CS2 market_hash_name values (skins, knives, gloves, stickers, cases, agents) from a loose query, e.g. 'ak redline ft', 'karambit doppler fn', 'st m4a1 printstream'. Use it before the price tools, which need exact names. Abbreviations: st = StatTrak, fn/mw/ft/ww/bs = exterior.
```

### `get_float_ranged_prices`

- The name "get_float_ranged_prices" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
YouPin898 lowest listing price per float range (e.g. 0.00-0.01, 0.01-0.02) for an item, in CNY, with Doppler phase and Fade % where relevant. Use it for low-float or high-fade valuations. Requires an API key (Pro plan).
```

### `get_price_history`

- The name "get_price_history" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Daily or hourly price history of one item on one marketplace (lowest listing price and listing count), in the market's currency. Daily covers up to a year and more, hourly up to 30 days. Requires an API key (Enterprise plan).
```

### `get_prices`

- The name "get_prices" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Live lowest listing prices for CS2 items on up to 12 marketplaces (YouPin898, BUFF163, C5Game, EcoSteam, SkinBaron, Skinport, CSFloat, LIS-SKINS, DMarket, ShadowPay, Waxpeer, Market.CSGO) plus the Steam Community Market best ask/bid. Refreshed about every 5 minutes. Prices are in each market's own currency (CNY, EUR or USD) with an approximate USD value for comparison, plus listing counts and the cheapest market. Doppler / Gamma Doppler names without a phase return every phase separately. Without an API key (preview): one item per call, 5 calls per day, prices from a snapshot up to 6 hours old.
```

### `get_recent_sales`

- The name "get_recent_sales" says "get": a word for reading.
- Tag private-data: The description's first sentence says "keychain": it reads secrets.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Recent completed sales of an item on CSFloat, YouPin or Skinport with price, float, pattern (paint seed), stickers and keychains. Filter by float range or pattern. Requires an API key (Enterprise plan).
```

### `get_youpin_buy_orders`

- The name "get_youpin_buy_orders" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

Current YouPin898 buy orders (bids) for an item, in CNY, refreshed about every 30 minutes. Default: best buy-order price and order count (Pro plan). With detail=true or any float/phase/fade/tier filter: every individual buy order with its float range and conditions (Enterprise plan). Requires an API key.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__cspriceapi__find_items",
      "mcp__cspriceapi__get_prices",
      "mcp__cspriceapi__get_youpin_buy_orders",
      "mcp__cspriceapi__get_float_ranged_prices",
      "mcp__cspriceapi__get_price_history",
      "mcp__cspriceapi__get_recent_sales"
    ],
    "ask": [],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__cspriceapi__find_items`: untrusted-input
- `mcp__cspriceapi__get_prices`: untrusted-input
- `mcp__cspriceapi__get_youpin_buy_orders`: untrusted-input
- `mcp__cspriceapi__get_float_ranged_prices`: untrusted-input
- `mcp__cspriceapi__get_price_history`: untrusted-input
- `mcp__cspriceapi__get_recent_sales`: private-data, untrusted-input
