Active Scanner for Mitmproxy2Swagger

This module provides an automated way to crawl, inspect, and fuzz API endpoints to generate a high-quality OpenAPI specification with latency metrics.

Components

1. Crawler (src/scanner/crawler.py): Explores a website, renders JavaScript (Playwright), and captures all network traffic.
2. Prober (src/scanner/prober.py): Actively probes discovered endpoints with multiple requests to gather statistical performance data.
3. Core (mitmproxy2swagger): Converts the captured traffic (HAR/Flow) into an OpenAPI Spec.

Usage Guide

Usage Guide

Run the full active scan in one click:

uv run scanner https://example.com

This will automatically:

1. Crawl the website to discover endpoints.
2. Start a proxy (mitmdump) in the background.
3. Probe/Fuzz the endpoints through the proxy.
4. Generate the final OpenAPI spec (final_spec.yaml).

With Authentication

Using Headers (e.g., Bearer Token):

uv run scanner https://api.example.com \
  --header "Authorization: Bearer YOUR_TOKEN"

Using Cookies (e.g., Session ID):

uv run scanner https://dashboard.example.com \
  --cookie "session_id=xyz123"

Advanced Usage

You can still customize the run:

uv run scanner https://example.com \
  --depth 3 \
  --proxy-port 8081 \
  --final-spec my_api.yaml

Requirements

• Python 3.10+
• uv package manager
• Playwright (uv run playwright install)

Setup

1. Installation

1. Install uv (if not already installed):

   curl -LsSf https://astral.sh/uv/install.sh | sh

2. Sync dependencies:

3. Install Playwright browsers:

   uv run playwright install

2. Development Setup

To ensure code quality, we use ruff and pre-commit.

1. Install pre-commit hooks:

   uv run pre-commit install

2. Run linting manually (optional):

   uv run ruff check .
   uv run ruff format .
