## π Key Features Implemented
### 1. Multi-Environment Support (9 Environments)
- β
Browser (fetch API)
- β
Node.js 18+ (native fetch)
- β
Node.js Legacy (http module)
- β
React Native (fetch API)
- β
Electron Main Process (file write)
- β
Electron Renderer Process (IPC)
- β
WeChat Mini Program (wx.request)
- β
PHP (curl)
- β
Python (requests library)
### 2. MCP Tools (7 Tools)
- β
`analyze_bug` - Analyze bug descriptions
- β
`detect_environment` - Auto-detect runtime environment
- β
`add_debug_logs` - Inject debug code
- β
`create_test_steps` - Generate test steps
- β
`read_debug_logs` - Read and analyze logs
- β
`remove_debug_logs` - Clean up debug code
- β
`list_debug_blocks` - List debug markers
### 3. HTTP API Endpoints (4 Endpoints)
- β
`POST /api/log` - Receive debug logs
- β
`GET /api/log` - Retrieve logs
- β
`DELETE /api/log` - Clear logs
- β
`GET /api/stats` - Get statistics
- β
`GET /health` - Health check
### 4. Smart Features
- β
Automatic environment detection
- β
Backup creation before modifications
- β
Debug marker system (// debug-start ... // debug-end)
- β
Iterative debugging workflow
- β
Automatic cleanup after fix
- β
Error handling and recovery
## π¦ Dependencies
### Runtime Dependencies
- `@modelcontextprotocol/sdk` ^1.0.4
- `express` ^4.18.2
- `cors` ^2.8.5
- `dotenv` ^16.3.1
### Development Dependencies
- `typescript` ^5.3.3
- `@types/node` ^20.10.0
- `@types/express` ^4.17.21
- `@types/cors` ^2.8.17
## π― How It Works
### Debugging Workflow
```
1. User reports bug
β
2. AI analyzes bug β Suggests causes
β
3. Detect environment β Auto-select adapter
β
4. Inject debug logs (with // debug-start markers)
β
5. Generate test steps
β
6. User tests β Sends logs via HTTP API
β
7. If not fixed β Analyze logs β Add more targeted logs
β
8. If fixed β Remove all debug code β Summarize
```
### Example Debug Code (Browser)
```javascript
// debug-start
fetch('http://localhost:3000/api/log', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({
timestamp: new Date().toISOString(),
level: 'info',
message: 'Login button clicked',
data: { username, formData }
})
}).catch(err => console.error('[Debug Log Failed]', err));
// debug-end
```
## π§ Configuration
**.env file:**
```env
DEBUG_PORT=3000
LOG_FILE=.debug/debug.log
```
**package.json scripts:**
```json
{
"build": "tsc",
"start": "node dist/index.js",
"dev": "tsc && node dist/index.js"
}
```
## β
Build Verification
```bash
npm install # β
Completed
npm run build # β
0 errors, 48 files compiled
```
**Compilation Results:**
- TypeScript compilation: β
SUCCESS
- Type checking: β
PASSED
- Source maps: β
GENERATED
- Declarations: β
GENERATED
## π Next Steps
### To Start Using:
1. **Start the server:**
```bash
npm start
```
2. **Configure MCP client** (Claude Desktop):
```json
{
"mcpServers": {
"debug-mcp": {
"command": "node",
"args": ["D:\\work\\debug-mcp\\dist\\index.js"],
"env": { "DEBUG_PORT": "3000" }
}
}
}
```
3. **Test the API:**
```bash
curl http://localhost:3000/health
```
4. **Start debugging!**
### To Extend:
- Add new adapters in `src/adapters/index.ts`
- Add detection logic in `src/adapters/detector.ts`
- Add MCP tools in `src/mcp/tools.ts`
- See ADAPTERS.md for detailed guide
