 ### 8.1 MCP 工具集成
 
-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。
+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 |
+| **HTTP** | `streamableHttp` 或 `http` | 通过 HTTP/SSE 连接远程服务器 | 远程 MCP servers、云服务 |
 
 **配置示例：**
 
 ```json

-    "enabled": true,

-    "servers": [
-      {

+**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 |
+| `env` | Stdio: 环境变量 | 否 |
+| `baseUrl` | HTTP: MCP server URL | HTTP 必填 |
+| `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
+
+```json
+{
+  "headers": {
+    "Authorization": "Bearer ${API_KEY}"
   }
 }
 ```
 
 **工具命名规则：**
 
-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_filesystem_read_file`
+- `mcp_filesystem_read_file` - server key 为 "filesystem"
 - `mcp_filesystem_write_file`
-- `mcp_filesystem_list_directory`
+- `mcp_WebSearch_search` - server key 为 "WebSearch"
-- `mcp_remote-tools_custom_query`
