+
+## 项目简介
+
+`arthas-mcp-server` 是 [Arthas](https://github.com/alibaba/arthas) 的实验模块，实现了基于 MCP（Model Context Protocol）协议的服务端。该模块通过 HTTP/Netty 提供统一的 JSON-RPC 2.0 接口，支持 AI 使用工具调用的方式执行 arthas 的命令。
+
+## 快速开始
+
+正常启动服务之后，服务对外暴露8563，在 cherry-studio/cline 等 ai 客户端中配置：
+
+在设置中添加 MCP 服务器：
+
+```JSON
+{
+  "mcpServers": {
+    "arthas-mcp": {
+      "transport": "sse",
+      "url": "http://localhost:8563/sse"
+    }
+  }
+}
