# Juhe Exchange Rates MCP Server

一个提供实时全球货币汇率查询功能的模型上下文协议（Model Context Protocol）服务器。该服务器使大型语言模型（LLMs）能够获取实时货币汇率情况。

## Components

### Tools

服务器实现了一个工具:

- query_exchange_rates: 根据货币的三位字母代码查询两者之间的兑换汇率
  - 需要传入 "from_code"（货币的三位字母货币代码）作为必须的字符串参数。
  - 需要传入 "to_code"（货币的三位字母货币代码）作为必须的字符串参数。
```
async def query_exchange_rates(
    from_code: str = Field(description="您希望转换的货币的三位字母货币代码。如：CNY"),
    to_code : str = Field(description="您希望转换为目标货币的三位字母货币代码。如：USD")
) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]:
```


## Install
This server requires Python 3.10 or higher. Install dependencies using uv (recommended) or pip

### Using uv (recommended)
When using [uv](https://docs.astral.sh/uv/) no specific installation is needed. We will use [uvx](https://docs.astral.sh/uv/guides/tools/) to directly run jexchange-mcp-server.

```bash
uvx jexchange-mcp-server
```

### Using PIP
Alternatively you can install jexchange-mcp-server via pip:
```
pip install jexchange-mcp-server
```
After installation, you can run it as a script using:
```
python -m jexchange_mcp_server
```

### Configuration

```bash
npx @modelcontextprotocol/inspector uvx jexchange-mcp-server 
```

Or if you've installed the package in a specific directory or are developing on it:

```bash
cd path/to/servers/src/jexchange-mcp-server
npx @modelcontextprotocol/inspector uv run jexchange-mcp-server
```
