# MCP Browser - Claude Code CLI Setup Complete ✅

## Configuration Status

The MCP Browser server is now properly configured as a project-based MCP server for Claude Code CLI.

### MCP Configuration Files

📁 **Main Configuration**: `mcp.json` (in project root)

This configuration tells Claude Code CLI how to run the MCP Browser server:

```json
{
  "mcpServers": {
    "mcp-browser": {
      "command": "/Users/masa/Projects/managed/mcp-browser/.venv/bin/python",
      "args": [
        "/Users/masa/Projects/managed/mcp-browser/mcp-server.py"
      ],
      "env": {
        "MCP_BROWSER_HOME": "/Users/masa/.mcp-browser",
        "PYTHONPATH": "/Users/masa/Projects/managed/mcp-browser",
        "PYTHONUNBUFFERED": "1"
      }
    }
  }
}
```

## Available MCP Tools

The following tools are now available in Claude Code:

### Core Browser Tools
- `browser_navigate` - Navigate to URLs
- `browser_query_logs` - Query console messages
- `browser_screenshot` - Take screenshots

### DOM Interaction Tools
- `browser_click` - Click elements on the page
- `browser_fill_field` - Fill individual form fields
- `browser_fill_form` - Fill multiple form fields at once
- `browser_submit_form` - Submit forms
- `browser_get_element` - Get element information
- `browser_wait_for_element` - Wait for elements to appear
- `browser_select_option` - Select dropdown options
- `browser_check_checkbox` - Check/uncheck checkboxes

## Testing the Integration

You can test the MCP tools right now in Claude Code by asking me to:

1. **Navigate somewhere**: "Use browser_navigate to go to https://example.com"
2. **Check console logs**: "Use browser_query_logs to check for any errors"
3. **Take a screenshot**: "Use browser_screenshot to capture the current page"
4. **Interact with forms**: "Use browser_fill_form to fill out a test form"

## Prerequisites

✅ **Completed**:
- MCP server configured in `.claude/mcp.json`
- WebSocket server running on port 8876
- Dashboard available at http://localhost:8080
- Chrome extension installed and connected

## Chrome Extension Status

The Chrome extension should show:
- **Name**: MCP Browser
- **Status**: Connected
- **Port**: 8876
- **Console Capture**: Active on all tabs

## Setup Verification

### ✅ Python Environment
- **Virtual Environment**: `/Users/masa/Projects/managed/mcp-browser/.venv`
- **Python Version**: 3.13.7
- **MCP Package**: Installed (v1.14.0)
- **All Dependencies**: Installed from requirements.txt

### ✅ Server Configuration
- **Entry Point**: `mcp-server.py` (executable, runs in MCP stdio mode)
- **Main CLI**: `src/cli/main.py` (handles MCP mode when 'mcp' argument passed)
- **Service Layer**: Fully implemented with SOA/DI architecture

### ✅ Data Directories
- **MCP Home**: `~/.mcp-browser/` (exists with proper structure)
- **Console Logs**: `~/.mcp-browser/data/`
- **Server Logs**: `~/.mcp-browser/logs/`

## How Claude Code CLI Discovers This Server

1. **Project-based Discovery**: When you're in the project directory, Claude Code CLI reads `mcp.json`
2. **Automatic Startup**: The server starts automatically when Claude Code needs it
3. **Stdio Communication**: Uses JSON-RPC over stdio for communication

## Testing the Setup

### Quick Test
Run the provided test script:
```bash
./test_mcp_server.sh
```

### Manual Test
```bash
# Test server initialization
echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"0.1.0","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}' | .venv/bin/python mcp-server.py
```

## Important Notes

1. **This is for Claude Code CLI**, not Claude Desktop
2. **Chrome Extension Required**: Must be installed for browser integration
3. **WebSocket Port Range**: 8875-8895 (auto-discovery)
4. **MCP Mode**: Server runs in stdio mode, no stdout logging

## Troubleshooting

### If Claude Code doesn't discover the server:
1. Ensure you're in the project directory: `/Users/masa/Projects/managed/mcp-browser`
2. Check that `mcp.json` exists in the project root
3. Verify the configuration structure matches the format above

### If the server doesn't respond:
1. Check Python dependencies: `.venv/bin/pip list | grep mcp`
2. Test the server directly: `.venv/bin/python mcp-server.py`
3. Check error logs in: `~/.mcp-browser/logs/`

### To reinstall dependencies:
```bash
.venv/bin/pip install -r requirements.txt
```
