## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `estimate_cost`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
估算一段文本或指定 token 数在某个大模型上的**输入侧**调用成本，以人民币 ¥ 计价。text_or_tokens 支持两种模式：传自然语言文本时自动估算 token 数（中文按字符、英文按词分别计），传纯数字字符串时直接作为已知 token 数使用。返回：所用估算方法、token 数、按原价计的输入成本；若该模型提供缓存输入价，另给出缓存命中成本、相对原价的节省百分比与倍数差价；末尾附该模型的输入 / 输出 / 缓存输入单价（每百万 tokens）。⚠[U+FE0F] 本工具只计算输入成本，不含输出 token 费用——要估算完整往返成本，需另取输出单价自行相加。
```

## Only reads (1)

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

### `query_model_price`

- The name "query_model_price" says "query": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
查询指定大模型（如 GPT-5, Claude, DeepSeek）的最新 API 输入、输出和缓存输入单价（单位：每百万 tokens）。
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__pricing__query_model_price"
    ],
    "ask": [
      "mcp__pricing__estimate_cost"
    ],
    "deny": []
  }
