# 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.
