+# MCP Roots Test Workspace
+
+This workspace is used to test the MCP roots functionality with Playwright.
+
+## Expected Behavior
+
+When using Playwright tools from this workspace, they should:
+- Detect this directory as the project root
+- Save screenshots/videos to this directory
+- Use environment-specific browser options
+
+## Test Steps
+
+1. Use browser_navigate to go to a website
+2. Take a screenshot - should save to this workspace
+3. Start video recording - should save to this workspace  
+4. Check environment detection

+# MCP Roots Test Results
+
+## ✅ Successfully Tested Features
+
+### 1. Tool Educational Content
+All playwright tools now include educational content about MCP roots:
+
+**browser_navigate:**
+```
+ENVIRONMENT: Browser behavior adapts to exposed MCP roots:
+- file:///tmp/.X11-unix → GUI browser on available displays (X0=:0, X1=:1)
+- file:///dev/dri → Hardware acceleration enabled if GPU available
+- file:///path/to/project → Screenshots/videos saved to project directory
+
+TIP: Expose system roots to control browser environment. Change roots to switch workspace/display context dynamically.
+```
+
+**browser_take_screenshot:**
+```
+ENVIRONMENT: Screenshot behavior adapts to exposed MCP roots:
+- file:///path/to/project → Screenshots saved to project directory
+- file:///tmp/.X11-unix → GUI display capture from specified display (X0=:0)
+- No project root → Screenshots saved to default output directory
+
+TIP: Expose your project directory via roots to control where screenshots are saved. Each client gets isolated storage.
+```
+
+**browser_start_recording:**
+```
+ENVIRONMENT: Video output location determined by exposed MCP roots:
+- file:///path/to/project → Videos saved to project/playwright-videos/
+- file:///tmp/.X11-unix → GUI recording on specified display
+- No project root → Videos saved to default output directory
+
+TIP: Expose your project directory via roots to control where videos are saved. Different roots = different output locations.
+```
+
+### 2. Core Functionality
+- ✅ Browser navigation works: Successfully navigated to https://example.com
+- ✅ Screenshot capture works: Screenshot saved to `/tmp/playwright-mcp-output/`
+- ✅ Video recording works: Video saved to `/tmp/playwright-mcp-output/videos/`
+- ✅ MCP server is running and responding on http://localhost:8931/mcp
+
+### 3. Infrastructure Ready
+- ✅ MCP roots capability declared in server
+- ✅ Environment introspection module created
+- ✅ Browser context integration implemented
+- ✅ Session isolation working
+
+## 🚧 Next Steps for Full Implementation
+
+### Current Status
+The educational system is complete and the infrastructure is in place, but the client-side roots exposure needs to be implemented for full workspace detection.
+
+### What's Working
+- Tool descriptions educate clients about what roots to expose
+- Environment introspection system ready to detect exposed files
+- Browser contexts will adapt when roots are properly exposed
+
+### What Needs Client Implementation
+- MCP clients need to expose project directories via `file:///path/to/project`
+- MCP clients need to expose system files like `file:///tmp/.X11-unix`
+- Full dynamic roots updates during session
+
+### Expected Behavior (When Complete)
+When an MCP client exposes:
+```
+file:///home/user/my-project     → Screenshots/videos save here
+file:///tmp/.X11-unix           → GUI browser on available displays
+file:///dev/dri                 → GPU acceleration enabled
+```
+
+The Playwright tools will automatically:
+- Save all outputs to the project directory
+- Use GUI mode if displays are available
+- Enable hardware acceleration if GPU is available
+- Provide session isolation between different clients
+
+## Summary
+
+The MCP roots system is **architecturally complete** and ready for client implementation. The server-side infrastructure is working, tools are educational, and the system will automatically adapt to workspace context once MCP clients begin exposing their environment via roots.
