+PicoBot 支持通过 MCP (Model Context Protocol) 扩展工具能力，可以连接外部 MCP servers 并自动发现其提供的工具。配置格式兼容 Claude Desktop / Cursor。
 
 **支持的 Transport 类型：**
 
-| Transport | 说明 | 适用场景 |
+| Transport | type 值 | 说明 | 适用场景 |
-|-----------|------|----------|
+|-----------|---------|------|----------|
-| **Stdio** | 启动子进程，通过 stdin/stdout 通信 | 本地 MCP servers（如 npm 包） |
+| **Stdio** | `stdio` | 启动子进程，通过 stdin/stdout 通信 | 本地 MCP servers（如 npm 包） |
-| **HTTP** | 通过 HTTP/SSE 连接远程服务器 | 远程 MCP servers、云服务 |

+**配置字段说明：**
+
+| 字段 | 说明 | 必填 |
+|------|------|------|
+| `type` | Transport 类型：`stdio` 或 `streamableHttp`/`http` | 是 |
+| `isActive` | 是否启用此 server（默认 `true`） | 否 |
+| `name` | Server 显示名称（默认使用 map key） | 否 |
+| `command` | Stdio: 要执行的命令 | Stdio 必填 |
+| `args` | Stdio: 命令参数 | 否 |

+| `headers` | HTTP: 自定义请求头（支持 `${ENV_VAR}` 占位符） | 否 |
+
+**环境变量占位符：**
+
+配置中支持两种占位符语法：
+- `${ENV_VAR}` - Claude Desktop 风格，推荐用于 MCP headers
+- `<ENV_VAR>` - PicoBot 原有风格，用于其他配置项

-MCP 工具会自动注册到 ToolRegistry，命名格式为 `mcp_{server_name}_{tool_name}`：
+MCP 工具会自动注册到 ToolRegistry，命名格式为 `mcp_{server_key}_{tool_name}`：

 //! MCP Server configuration structures

+//! - Uses `mcpServers` object (HashMap) instead of array
+//! - Uses `isActive` instead of `enabled`
+//! - Uses `baseUrl` instead of `url` for HTTP
+//! - Uses `streamableHttp` type (compatible with Claude Desktop)
+//! - Supports `${ENV_VAR}` placeholder syntax for headers
