# R2AI MCP 插件

基于 [R2AIBridge](https://github.com/muort521/R2AIBridge) 的 MCP（Model Context Protocol）插件，通过 R2AIBridge 的 HTTP API **动态获取工具列表**并将工具调用转发到 Android 端。

## 功能

- **动态工具列表**：启动时或客户端请求时从 R2AIBridge 的 `tools/list` 获取当前可用工具，无需在代码中写死
- **透明转发**：客户端调用 `tools/call` 时，本服务将请求转发到 R2AIBridge 的 `/mcp` 端点
- **配置驱动**：R2AIBridge 的 base URL、超时等均在 `config.json` 中配置

## 配置

在项目根目录修改 `.env`，也可通过环境变量指定配置：

```bash
R2AI_BASEURL=http://127.0.0.1:5050
R2AI_TIMEOUT=30000
```

## 安装与运行

```bash
npm install r2ai-mcp
```

## 在 客户端 中配置

在客户端的 MCP 配置（例如 `mcp.json`）中添加：

```json
{
  "mcpServers": {
    "r2ai": {
      "command": "npx",
      "args": ["@hujiayucc/r2ai-mcp"],
      "env": {
        "R2AI_BASEURL": "http://127.0.0.1:5050",
        "R2AI_TIMEOUT": 30000
      }
    }
  }
}
```


## 依赖

- Node.js >= 18
- 已启动的 R2AIBridge 服务（Android 设备上运行 R2AIBridge 应用并点击「启动服务」）

## 协议说明

- 本服务实现 MCP 的 **stdio** 传输，与 R2AIBridge 的 **HTTP JSON-RPC 2.0** 接口对接
- 工具列表来自 R2AIBridge `POST {url}/mcp`、`method: "tools/list"`
- 工具调用为 `method: "tools/call"`，`params: { name, arguments }`
