OpenOSINT

OpenOSINT is an open-source OSINT framework with 20 intelligence tools, an MCP server, and an AI-powered REPL.

OpenOSINT is a modular open-source OSINT framework designed for security researchers, analysts, and investigators. It features an interactive terminal REPL, a direct command-line interface, and an MCP server that integrates with AI clients like Claude. Users can investigate emails, IP addresses, domains, usernames, phone numbers, and data breaches automatically using natural language prompts. The framework includes tools for subdomain enumeration, WHOIS data retrieval, Google dork generation, pastebin searches, and geolocation. It supports local inference via Ollama as well as Anthropic and OpenRouter models, and runs on Python 3.10 or later.
