I built an AI agent that runs autonomous OSINT investigations from your terminal
Short summary
OpenOSINT is an open-source Python framework that automates OSINT investigations using Claude's tool-use API. You describe a target in natural language, and the agent autonomously chains nine tools (email search, breach checks, username pivots, WHOIS, IP lookup) to compile structured findings. Available as interactive REPL, CLI, or MCP server for Claude Code integration.
- •OpenOSINT automates OSINT investigations with Claude API and native tool use—no manual tool switching
- •Nine tools chain automatically: email/username search, breach checks, domain enumeration, geolocation, and more
- •Available as interactive REPL, CLI, or MCP server for seamless Claude Code integration
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
