✨ Key Features

• 🔎 Deep Email & Username OSINT: Look up email registrations and perform advanced username profiling across 2710+ platforms.
• 👤 Rich Metadata Scraping: Scrapes avatars, bio descriptions, follower counts, UID numbers, seller statuses, and account attributes.
• 🔀 Cross-Scan & Pivot Engine: Mines handles, profile links, and exposed email addresses from initial scans, automatically pivoting across secondary target vectors.
• 🤖 Model Context Protocol (MCP) Server: Native AI agent integration for Claude Desktop, Cursor, Antigravity, and LLMs to run autonomous OSINT scans and recursive pivots.
• 🛡️ Hudson Rock Infostealer Breach Intel: Query infostealer malware breach logs using the --hudson flag for high-priority target correlation.
• ⚡ High-Throughput Parallel Engine: Powered by httpx and curl_cffi for maximum concurrency with automated TLS fingerprint impersonation.
• 🔀 Permutation & Alias Generator: Wildcard-based username variation generation to catch typosquatting or alternative aliases.
• 📂 Multi-Format Reports: Automated exports to PDF (with profile photos), JSON, and CSV for pipeline integration.
• 🌐 Advanced Proxy Pivoting: Built-in proxy rotation with protocol auto-detection (http, socks5) and pre-scan reachability check (--validate-proxies).
• 🎨 Responsive Terminal UI: Dynamic progress tracking, self-adaptive category grids (-lu/-le), and clear status reporting.

🚀 Installation

🐍 Via PyPI (Recommended)

# Upgrade pip and install user-scanner
python3 -m pip install --upgrade pip
pip install user-scanner

# Optional: Install with MCP Server support for AI agents
pip install "user-scanner[mcp]"

📦 Virtual Environment Setup

# Create and activate virtual environment
python3 -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\Activate.ps1

# Install package
pip install user-scanner

❄️ Via Nix (Linux & macOS)

# Run instantly without installing permanently
nix run github:kaifcodec/user-scanner/main -- --help

# Drop into a temporary shell with user-scanner active
nix shell github:kaifcodec/user-scanner/main

💻 Usage Guide

1. Basic Username & Email Scanning

Scan a single username or email address across all available platform modules:

user-scanner -u johndoe             # Single username scan
user-scanner -e johndoe@gmail.com   # Single email scan
user-scanner -u johndoe --email-domains global  # Try johndoe across provider domains

2. Cross-Scan & Pivot Intelligence

An email scan proves an account exists but rarely reveals a handle. --cross-scan mines exposed handles, profile links, and secondary email addresses from target profiles, pivoting into multi-pass reconnaissance across all matching platforms:

user-scanner -u johndoe --cross-scan                                  # Pivot from username scan
user-scanner -e johndoe@gmail.com --cross-scan                        # Pivot from email scan
user-scanner -e johndoe@gmail.com --cross-scan --cross-links verified # Platform-verified links only
user-scanner -u johndoe --cross-scan --cross-depth 2        # Follow links two hops deep

💡 For confidence scoring, link classification rules, and cost models, see docs/CROSS_SCAN.md.

3. Hudson Rock Malware Breach Intelligence

Check if a target username or email address has been exposed in infostealer malware infection logs:

user-scanner -u johndoe --hudson             # Username malware log check
user-scanner -e johndoe@gmail.com --hudson   # Email malware log check

🖼️ To view output terminal screenshots and visual previews, see docs/EXAMPLES.md.

4. Targeted Category & Module Scanning

Scan specific categories or individual modules, or list available modules in a responsive grid:

user-scanner -u johndoe -c dev                # Developer platforms only
user-scanner -e johndoe@gmail.com -m github   # Single module check
user-scanner -u johndoe -m github,instagram   # Specific comma-separated modules

user-scanner -lu                              # List user categories & modules grid
user-scanner -le                              # List email categories & modules grid

5. Bulk File Scanning

Scan multiple targets from an input file (one target per line):

user-scanner -uf usernames.txt   # Bulk username scan
user-scanner -ef emails.txt      # Bulk email scan

6. Report Exports, Options & Proxies

# Export results to PDF, JSON, or CSV
user-scanner -u johndoe -f pdf -o report.pdf
user-scanner -u johndoe -f json -o results.json

# Verbose URL reporting and show all results (including not found)
user-scanner -u johndoe -v --all

# Rotate proxies with a pre-scan reachability check
user-scanner -u johndoe -P proxies.txt --validate-proxies

7. AI & LLM Agent Integration (MCP Server)

Connect user-scanner directly to AI coding assistants and LLM platforms via the Model Context Protocol (MCP). This enables AI agents (Claude Desktop, Cursor, Antigravity, Open-WebUI) to autonomously investigate handles and emails, pivot on exposed profiles, and analyze digital footprints.

Starting the Server

# Start the MCP server over standard I/O (stdio)
user-scanner-mcp

# Optional: Enable verbose logging to stderr
user-scanner-mcp -v

MCP Client Configuration

Add user-scanner to your client configuration (e.g. claude_desktop_config.json or mcp_config.json):

{
  "mcpServers": {
    "user-scanner": {
      "command": "user-scanner-mcp"
    }
  }
}

Exposed AI Tools

An unknown category or module name is rejected with an error that suggests the closest valid names, so a typo never comes back as a scan with no findings. Use list_available_modules to see the full catalog.

🐍 Python Library Mode

Integrate the User Scanner engine directly into your Python scripts:

import asyncio
from user_scanner.core import engine
from user_scanner.email_scan.shopping import etsy

async def main():
    # Engine validates target against module and returns Result object
    result = await engine.check(etsy, "test@gmail.com")
    print(result.to_json())

asyncio.run(main())
