Give it a handle and hundreds of public sites get checked for a matching profile, then a report lands in a folder you chose as a web page, PDF, plain text or spreadsheet. A second option takes a profile link and works backwards to the name behind it. Nothing is purchased or logged into: the open-source Maigret tool runs inside Docker on your own machine. Matches are leads rather than proof, since strangers often share a handle.

Maigret MCP Server

smithery badge

A Model Context Protocol (MCP) server for maigret, a powerful OSINT tool that collects user account information from various public sources. This server provides tools for searching usernames across social networks and analyzing URLs. It is designed to integrate seamlessly with MCP-compatible applications like Claude Desktop.

⚠️ Warning

This tool is designed for legitimate OSINT research purposes. Please:

  • Only search for information that is publicly available
  • Respect privacy and data protection laws
  • Follow the terms of service of the platforms being searched
  • Use responsibly and ethically
  • Be aware that some sites may rate-limit or block automated searches

Security

This server implements several security measures to prevent command injection attacks:

Input Validation

  • Usernames: Only alphanumeric characters, underscores, hyphens, and periods are allowed (max 100 characters)
  • URLs: Must be valid HTTP/HTTPS URLs without shell metacharacters
  • Tags: Only alphanumeric characters, underscores, and hyphens are allowed

Safe Command Execution

  • Uses execFile() instead of exec() to prevent shell interpolation
  • All command arguments are passed as arrays, not concatenated strings
  • Docker commands are executed without shell interpretation

mcp-maigret FAQ

Is this still maintained?
The last commit was January 2026 and nothing is archived. Maigret, the tool it drives, is a separate project with its own release schedule.
Do I need to pay for anything or get a key?
No. It reads public pages only, so there is no account, subscription or paid service behind it.
How hard is setup?
Beyond copy-and-paste. Docker must be installed and running, and you need a folder it is allowed to write reports into.
Can I use this to check my own online footprint?
Yes. Search your own handle and you get back a report of every public site where that name turns up.
Does a match prove it is the same person?
No. Unrelated people pick the same handle all the time, so treat every hit as something to verify rather than a fact.
What do I actually get back?
A report file saved to your chosen folder, in whichever format you asked for: web page, PDF, plain text, spreadsheet or mind map.
Which apps does it work in?
Claude Desktop is documented, with a one-command install through Smithery. Other MCP-compatible apps use the same settings.
Is this allowed?
It reads only public information, but the project asks you to respect privacy law and each site's rules, and some sites block repeated automated lookups.
