### Description (declared)

# MCP 翻译服务 
 
基于小牛翻译（Niutrans）API 的 MCP Provider，提供文字翻译工具和语种目录资源，方便在 Cursor/mcp-cli 等客户端中引用。 
 
## 快速开始 
 
### 使用 uv 安装并启动发布版 
 
```bash 
uv tool install mcp-translation-text 
``` 
 
## 环境变量 
 
- `NIUTRANS_API_KEY`（必填）：小牛翻译开放平台提供的 API Key,可免费使用, 请登录后获取:https://niutrans.com/cloud/account_info/info 
 
## MCP 客户端配置示例 
 
若通过 `uv tool install` 安装，可在 `mcp.json` 中写： 
 
```json 
{ 
  "mcpServers": { 
    "translation": { 
      "type": "stdio", 
      "command": "uv", 
      "args": [ 
        "tool", 
        "run", 
        "mcp-translation-text" 
      ], 
      "env": { 
        "NIUTRANS_API_KEY": "${env.NIUTRANS_API_KEY}" 
      } 
    } 
  } 
} 
``` 
 
启动 Cursor 后执行 `ListTools` 即可看到 `translate_text`，同时支持 `ListResources` 读取 `language://catalog`。 
 
## 可用功能 
 
### 工具：`translate_text` 
 
- **参数**： 
  - `text`：待翻译内容。 
  - `source`：源语言代码或别名（会通过本地映射表规范化）。 
  - `target`：目标语言代码或别名。 
- **返回**： 
  ```json 
  { 
    "source": "zh", 
    "target": "en", 
    "original_text": "你好", 
    "translated_text": "Hello", 
    "raw": { ... 小牛原始响应 ... } 
  } 
  ``` 
 
### 资源：`language://catalog` 
 
提供所有可用语种及别名，示例如下： 
 
```json 
{ 
  "total": 455, 
  "languages": [ 
    {"code": "zh", "zh": "中文(简体)", "en": "Chinese (Simplified)"}, 
    {"code": "en", "zh": "英语", "en": "English"} 
    // ... 其余省略 ... 
  ], 
  "aliases": { 
    "zhongwenjianti": "zh", 
    "english": "en" 
    // ... 其余省略 ... 
  } 
} 
``` 
 
推荐在客户端的 LLM 中先读取该资源，完成语种描述到代码的映射后，再调用 `translate_text`。 
 
## 调试与常见问题 
 
- **缺少 API Key**：启动时报 `缺少环境变量 NIUTRANS_API_KEY`，请确认已在 `.env` 或系统环境中设置。 
- **语种不支持**：`translate_text` 会校验语种代码/别名，若报错请检查是否使用了 `language://catalog` 中列出的值。 
- **路径或依赖问题**：脚本依赖 `uv`，请先安装 `pip install uv` 或参考 [uv 文档](https://github.com/astral-sh/uv)。 
- **命令名称**：通过 PyPI 安装后，可直接运行 `mcp-translation-text`；若 global PATH 中找不到，记得激活虚拟环境或使用 `python -m mcp_translation_text`。 
- **发布/升级包**： 
  ```bash 
  python -m build 
  twine upload dist/* 
  ```
