+### Proxy Configuration (proxychains4)
+
+MCPHub supports routing STDIO server network traffic through a proxy using **proxychains4**. This feature is available on **Linux and macOS only** (Windows is not supported).
+
+<Note>
+To use this feature, you must have `proxychains4` installed on your system:
+- **Debian/Ubuntu**: `apt install proxychains4`
+- **macOS**: `brew install proxychains-ng`
+- **Arch Linux**: `pacman -S proxychains-ng`
+</Note>
+
+#### Basic Proxy Configuration
+
+```json
+{
+  "mcpServers": {
+    "fetch-via-proxy": {
+      "command": "uvx",
+      "args": ["mcp-server-fetch"],
+      "proxy": {
+        "enabled": true,
+        "type": "socks5",
+        "host": "127.0.0.1",
+        "port": 1080
+      }
+    }
+  }
+}
+```
+
+#### Proxy Configuration Options
+
+| Field        | Type    | Default   | Description                                      |
+| ------------ | ------- | --------- | ------------------------------------------------ |
+| `enabled`    | boolean | `false`   | Enable/disable proxy routing                     |
+| `type`       | string  | `socks5`  | Proxy protocol: `socks4`, `socks5`, or `http`    |
+| `host`       | string  | -         | Proxy server hostname or IP address              |
+| `port`       | number  | -         | Proxy server port                                |
+| `username`   | string  | -         | Proxy authentication username (optional)         |
+| `password`   | string  | -         | Proxy authentication password (optional)         |
+| `configPath` | string  | -         | Path to custom proxychains4 config file          |
+
+#### Proxy with Authentication
+
+```json
+{
+  "mcpServers": {
+    "secure-server": {
+      "command": "npx",
+      "args": ["-y", "@example/mcp-server"],
+      "proxy": {
+        "enabled": true,
+        "type": "http",
+        "host": "proxy.example.com",
+        "port": 8080,
+        "username": "${PROXY_USER}",
+        "password": "${PROXY_PASSWORD}"
+      }
+    }
+  }
+}
+```
+
+#### Using Custom proxychains4 Configuration
+
+For advanced use cases, you can provide your own proxychains4 configuration file:
+
+```json
+{
+  "mcpServers": {
+    "custom-proxy-server": {
+      "command": "python",
+      "args": ["-m", "custom_mcp_server"],
+      "proxy": {
+        "enabled": true,
+        "configPath": "/etc/proxychains4/custom.conf"
+      }
+    }
+  }
+}
+```
+
+<Tip>
+When `configPath` is specified, all other proxy settings (`type`, `host`, `port`, etc.) are ignored, and the custom configuration file is used directly.
+</Tip>

+### Progressive Disclosure Mode
+
+Progressive Disclosure is an optimization feature that reduces token usage when working with Smart Routing. When enabled, the tool discovery workflow changes from a 2-step to a 3-step process.
+
+<AccordionGroup>
+  <Accordion title="What is Progressive Disclosure?">
+    By default, Smart Routing returns full tool information including complete parameter schemas in `search_tools` results. This can consume significant tokens when dealing with tools that have complex input schemas.
+    
+    **Progressive Disclosure** changes this behavior:
+    - `search_tools` returns only tool names and descriptions (minimal info)
+    - A new `describe_tool` endpoint provides full parameter schema on demand
+    - `call_tool` executes the tool as before
+    
+    This approach is particularly useful when:
+    - Working with many tools with complex schemas
+    - Token usage optimization is important
+    - AI clients need to browse many tools before selecting one
+  </Accordion>
+
+  <Accordion title="Enabling Progressive Disclosure">
+    Enable Progressive Disclosure through the Settings page or environment variable:
+    
+    **Via Settings UI:**
+    1. Navigate to Settings → Smart Routing
+    2. Enable the "Progressive Disclosure" toggle
+    3. The change takes effect immediately
+    
+    **Via Environment Variable:**
+    ```bash
+    SMART_ROUTING_PROGRESSIVE_DISCLOSURE=true
+    ```
+  </Accordion>
+
+  <Accordion title="Standard Mode (Default)">
+    When Progressive Disclosure is **disabled** (default), Smart Routing provides two tools:
+    
+    **Workflow:** `search_tools` → `call_tool`
+    
+    | Tool | Purpose |
+    |------|---------|
+    | `search_tools` | Find tools by query, returns full tool info including `inputSchema` |
+    | `call_tool` | Execute a tool with the provided arguments |
+    
+    This mode is simpler but uses more tokens due to full schemas in search results.
+  </Accordion>
+
+  <Accordion title="Progressive Disclosure Mode">
+    When Progressive Disclosure is **enabled**, Smart Routing provides three tools:
+    
+    **Workflow:** `search_tools` → `describe_tool` → `call_tool`
+    
+    | Tool | Purpose |
+    |------|---------|
+    | `search_tools` | Find tools by query, returns only name and description |
+    | `describe_tool` | Get full schema for a specific tool (new) |
+    | `call_tool` | Execute a tool with the provided arguments |
+    
+    **Example workflow:**
+    1. AI calls `search_tools` with query "file operations"
+    2. Results show tool names and descriptions (minimal tokens)
+    3. AI calls `describe_tool` for a specific tool to get full `inputSchema`
+    4. AI calls `call_tool` with the correct arguments
+    
+    This mode reduces token usage by only fetching full schemas when needed.
+  </Accordion>

+    | 工具 | 用途 |
+    |------|------|
+    | `search_tools` | 按查询查找工具，只返回名称和描述 |
+    | `describe_tool` | 获取特定工具的完整模式（新增） |
+    | `call_tool` | 使用提供的参数执行工具 |
+    
+    **示例工作流：**
+    1. AI 使用查询 "文件操作" 调用 `search_tools`
+    2. 结果显示工具名称和描述（最少 Token）
+    3. AI 为特定工具调用 `describe_tool` 获取完整的 `inputSchema`
+    4. AI 使用正确的参数调用 `call_tool`
+    
+    这种模式通过仅在需要时获取完整模式来减少 Token 使用。
