### Description (declared)

# mcp-vos-auth

用于 FastMCP 的工具调用鉴权 middleware。它在工具执行前通过 Vinehoo 接口验证 `token`，
再根据工具名查询允许调用该工具的角色；只有用户角色与工具角色存在交集时才执行工具。

## 安装

### 通过 PyPI 安装

```bash
pip install mcp-vos-auth
```

### 不通过 pip 使用

无论采用下面哪种方式，目标项目都必须提供本包的运行依赖：

```bash
pip install fastmcp httpx
```

#### 方式一：设置 `PYTHONPATH`（本地多项目开发推荐）

将本项目的 `src` 目录加入 Python 模块搜索路径：

```bash
export PYTHONPATH="/path/to/mcp-vos-auth/src:$PYTHONPATH"
python your_server.py
```

例如本仓库位于 `/Users/vber/Documents/codes/mcp-vos-auth` 时：

```bash
export PYTHONPATH="/Users/vber/Documents/codes/mcp-vos-auth/src:$PYTHONPATH"
python your_server.py
```

目标项目不需要修改导入语句：

```python
from mcp_vos_auth import register_token_auth
```

`PYTHONPATH` 只对当前终端会话有效。需要长期使用时，可将 `export` 命令加入 shell 配置，
或写入项目的启动脚本。

#### 方式二：在程序入口添加源码路径（仅建议临时调试）

```python
import sys

sys.path.insert(0, "/path/to/mcp-vos-auth/src")

from mcp_vos_auth import register_token_auth
```

这种方式会把本机绝对路径写入业务代码，不适合多人协作或生产部署。

#### 方式三：将包源码复制到目标项目

把本仓库的 `src/mcp_vos_auth` 目录完整复制到目标项目根目录：

```text
your-project/
├── your_server.py
└── mcp_vos_auth/
    ├── __init__.py
    └── middleware.py
```

然后正常导入：

```python
from mcp_vos_auth import register_token_auth
```

该方式部署简单，但复制后的源码不会自动同步本仓库后续的修复和升级，需要自行维护版本。

以上三种方式都不需要安装 `mcp-vos-auth` 本身。对于本地联调，优先使用 `PYTHONPATH`；
对于需要固定源码且不使用包管理的部署，可复制 `mcp_vos_auth` 目录。

## 使用

调用默认 token 校验接口前，需要配置 MCP secret：

```bash
export VINEHOO_MCP_SECRET="your-secret"
```

middleware 会将该值作为 `vinehoo-mcp-secret` 请求 header 发送。

```python
from fastmcp import Context, FastMCP
from mcp_vos_auth import get_token_data, register_token_auth

mcp = FastMCP("protected-server")

# 自动创建 middleware 并注册到当前 FastMCP 实例。
register_token_auth(mcp, platform="app")

@mcp.tool
def get_order(order_id: int, token: str) -> dict:
    return {"order_id": order_id}

if __name__ == "__main__":
    mcp.run()
```

工具函数可通过 FastMCP 注入的 `Context` 获取校验接口返回的完整 `data`，包括
`telephone`、`uid`、`userid`、`realname` 和 `roles`：

```python
@mcp.tool
async def current_user(token: str, ctx: Context) -…
