What it solves

User Scanner is an OSINT (Open Source Intelligence) suite designed to map a person's digital footprint. It solves the problem of manually searching hundreds of websites to see where a specific email address or username is registered, automating the process of uncovering account registrations and associated metadata.

How it works

The tool uses a high-throughput parallel engine to scan over 465 platforms (175+ for emails and 290+ for usernames). It scrapes public data such as avatars, bios, and follower counts. A key feature is its "Cross-Scan & Pivot Engine," which finds new handles or emails on one profile and automatically uses them to search other platforms. It also integrates with Hudson Rock to check for credentials in malware breach logs and provides an MCP server to allow AI agents to run these scans autonomously.

Who it’s for

It is built for professional investigators, cybersecurity analysts, and security researchers performing authorized OSINT investigations or defensive research.

Highlights

• Massive Coverage: Scans 465+ total vectors across various platform categories.
• AI Integration: Native Model Context Protocol (MCP) server for use with LLMs like Claude and Cursor.
• Cross-Scanning: Automatically pivots from one discovered handle or email to find further accounts.
• Breach Intel: Integration with Hudson Rock infostealer logs.
• Flexible Reporting: Exports results to PDF, JSON, and CSV formats.
• Advanced Networking: Supports proxy rotation and TLS fingerprint impersonation to avoid detection.
