User Scanner
A powerful 2-in-1 OSINT suite engineered for deep Email and Username Intelligence.
With 550+ total scan vectors—including 175+ email-integrated sites and 375+ username platforms—you can map digital footprints, analyze target behavior, uncover interests, full metadata of usernames and verify account registrations in seconds.
Go beyond account enumeration. WebVetted turns an email or username into a complete identity investigation with deep OSINT enrichment, breach intel, AI analysis, and an interactive identity graph.

✨ Key Features
- 🔎 Deep Email & Username OSINT: Look up email registrations and perform advanced username profiling across 550+ 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 health validation (--validate-proxies).
- 🎨 Responsive Terminal UI: Dynamic progress tracking, self-adaptive category grids (
-lu/-le), and clear status reporting.

💻 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 [email protected] # Single email scan
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:
| Pivot Direction |
What it Mines |
-e → username |
Handles or social links exposed on an email's registered profile |
-u → username |
Secondary aliases advertised across target social profiles |
-u → email |
Public email addresses published on target profile pages |
-e → email |
Secondary addresses exposed by initial email profiles |
user-scanner -u johndoe --cross-scan # Pivot from username scan
user-scanner -e [email protected] --cross-scan # Pivot from email scan
user-scanner -e [email protected] --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 [email protected] --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 [email protected] -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 pre-scan validation 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"
}
}
}

🐍 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, "[email protected]")
print(result.to_json())
asyncio.run(main())
💡 *For complete Python API documentation and batch category checking examples, see docs/USAGE.md.*
