 #### mcpServers
 
 Configures connections to one or more Model-Context Protocol (MCP) servers for discovering and using custom tools. Qwen Code attempts to connect to each configured MCP server to discover available tools. If multiple MCP servers expose a tool with the same name, the tool names will be prefixed with the server alias you defined in the configuration (e.g., `serverAlias__actualToolName`) to avoid conflicts. Note that the system might strip certain schema properties from MCP tool definitions for compatibility. At least one of `command`, `url`, or `httpUrl` must be provided. If multiple are specified, the order of precedence is `httpUrl`, then `url`, then `command`.

 This example demonstrates how you can provide general project context, specific coding conventions, and even notes about particular files or components. The more relevant and precise your context files are, the better the AI can assist you. Project-specific context files are highly encouraged to establish conventions and context.

+- **Hierarchical Loading and Precedence:** The CLI implements a hierarchical memory system by loading context files (e.g., `QWEN.md`) from several locations. Content from files lower in this list (more specific) typically overrides or supplements content from files higher up (more general). The exact concatenation order and final context can be inspected using the `/memory show` command. The typical loading order is:
   1. **Global Context File:**
      - Location: `~/.qwen/<configured-context-filename>` (e.g., `~/.qwen/QWEN.md` in your user home directory).
      - Scope: Provides default instructions for all your projects.
   2. **Project Root & Ancestors Context Files:**
      - Location: The CLI searches for the configured context file in the current working directory and then in each parent directory up to either the project root (identified by a `.git` folder) or your home directory.
      - Scope: Provides context relevant to the entire project or a significant portion of it.
-  3. **Sub-directory Context Files (Contextual/Local):**
-     - Location: The CLI also scans for the configured context file in subdirectories _below_ the current working directory (respecting common ignore patterns like `node_modules`, `.git`, etc.). The breadth of this search is limited to 200 directories by default, but can be configured with the `context.discoveryMaxDirs` setting in your `settings.json` file.
-     - Scope: Allows for highly specific instructions relevant to a particular component, module, or subsection of your project.
 - **Concatenation & UI Indication:** The contents of all found context files are concatenated (with separators indicating their origin and path) and provided as part of the system prompt. The CLI footer displays the count of loaded context files, giving you a quick visual cue about the active instructional context.
 - **Importing Content:** You can modularize your context files by importing other Markdown files using the `@path/to/file.md` syntax. For more details, see the [Memory Import Processor documentation](../configuration/memory).
