This system combines three sophisticated technologies to create an intelligent, self-optimizing automation platform:
- Integuru: API reverse-engineering via HAR/network analysis (fastest automation path)
- mitmproxy: Real-time network interception & activity recording at multiple levels
- CDP MCP Server: Browser state capture, headless replication, and visual debugging
Key Innovation: The system automatically chooses the fastest viable automation modality for each task by analyzing the network traffic you generate, eliminating the speed penalty of traditional browser automation.

Purpose: Capture all HTTP(S) traffic to enable API reverse-engineering
# Start mitmproxy with HAR recording
mitmdump --set hardump=network_requests.har \
--flow-detail=3 \
--set confdir=~/.mitmproxy \
-q
# Or with Python addon for custom processing:
mitmdump -s record_addon.py --set record_level=3What's recorded:
- Full request/response headers
- Request/response bodies
- Timing information
- Cookie jar state
- WebSocket frames (if applicable)
Output: network_requests.har (standard HAR format, compatible with Integuru)
Purpose: Capture browser automation state separately for debugging & replay

User Action (visible browser):
"Download my generated image"
↓
mitmproxy captures ALL HTTP(S)
↓
network_requests.har generated
↓
Integuru analyzes HAR + your prompt
↓
Identifies final request (e.g., GET /api/v1/image/123/download)
↓
Builds dependency graph:
├─ GET /api/auth/verify
├─ GET /api/user/profile
├─ GET /api/projects/{projectId}/images
├─ POST /api/images/{imageId}/generate
└─ GET /api/images/{imageId}/download ← TARGET
↓
Extracts dynamic parameters from responses
↓
Generates Python code:
```python
def download_image(auth_token):
# Step 1: Verify auth
headers = {"Authorization": f"Bearer {auth_token}"}
verify = requests.get("https://api.klingai.com/auth/verify", headers=headers)
# Step 2: Get user profile (to extract projectId from response)
profile = requests.get("https://api.klingai.com/user/profile", headers=headers)
project_id = profile.json()['current_project_id']
# Step 3: List images
images = requests.get(f"https://api.klingai.com/projects/{project_id}/images", headers=headers)
image_id = images.json()['images'][-1]['id']
# Step 4: Download
download = requests.get(f"https://api.klingai.com/images/{image_id}/download", headers=headers)
return download.content
↓
MCP executes code in ~2-3 seconds ↓ Image downloaded successfully

}| Modality | Time | Method |
|---|---|---|
| Integuru | 2-5s | Direct API calls |

| Visible Browser | 5-10min | User performs manually |
Integuru (3 API calls):
├─ GET /api/auth/verify 150ms
├─ GET /api/projects/images 200ms
└─ GET /api/images/{id}/download 250ms
Total: 600ms
Headless CDP (5+ requests):
├─ Page load + JS execution 2000ms
├─ API calls 3000ms
├─ Screenshots + GLM analysis 5000ms
└─ Overhead 10000ms
Total: 20000ms
- Network Layer: mitmproxy is running on localhost → invisible to external observers
- API Layer: Integuru-generated code uses real API endpoints → not detectable as automation
- Browser Layer: CDP extension hides
navigator.webdriver→ appears as normal user - Session Layer: Replicated browser state includes full authentication → no re-login needed
- All HAR files stored locally (no cloud upload)
- mitmproxy addon doesn't log sensitive data by default
- Execution logs exclude credentials (extension filters them)
- Screenshots stored encrypted if needed
Each execution feeds back into optimization:
1. Record execution time for each modality
2. Track success/failure rates
3. Measure Integuru code generation quality
4. Update modality optimizer weights
→ Next execution automatically chooses faster route based on history

Tracks:
- Modality selection accuracy
- Execution time vs. estimate
- Success rate per site
- API stability (HAR changes)
- Code generation quality
"""- Install Integuru + dependencies
- Configure mitmproxy with HAR recording
- Deploy CDP extension for state capture
- Set up MCP server with all tools
- Create mitmproxy addon for activity logging

- Implement modality optimizer
- Build metrics collection
- Document automation workflows
- Set up CI/CD for continuous improvement
- Speed: Integuru finds fastest path automatically (2-5s instead of 20-30s)
