| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__paletteget__list_palettes` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `suggest_palette`

- 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
按自然语言关键词推荐配色（中英文均可），例如「护眼的深色记账 App」「清新博客」。会说明每个结果命中了什么。
```

## Only reads (3)

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

### `get_css_variables`

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

Description, as the server wrote it:

```untrusted-server-text
取一套配色的 CSS 自定义属性（可直接粘进项目），含语义化变量名。
```

### `get_palette`

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

Description, as the server wrote it:

```untrusted-server-text
取某一套配色的完整数据：角色色值（主色 / 功能色 / 中性色）、对比度、人工搭配建议。
```

### `list_palettes`

- The name "list_palettes" says "list": a word for reading.
- Tag untrusted-input: The description's first sentence says "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
列出配色库中的配色，可按平台（app / web / miniapp）与标签过滤。返回名称、slug、主色、场景与标签。
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__paletteget__list_palettes",
      "mcp__paletteget__get_palette",
      "mcp__paletteget__get_css_variables"
    ],
    "ask": [
      "mcp__paletteget__suggest_palette"
    ],
    "deny": []
  }
}
```

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

- `mcp__paletteget__list_palettes`: untrusted-input

| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://paletteget-mcp.y7206062.workers.dev/mcp: tools/list returned 4 tools to an anonymous client, including suggest_palette (write)
```
