# OpenOSINT (MCP server)

> OpenOSINT is an MCP server that adds developer tools to AI assistants such as Claude Desktop, Claude Code and Cursor. AI-powered OSINT agent & MCP server. 21 tools: email, breach, IP, WHOIS, DNS, Shodan, GitHub & more. It has 1,700 GitHub stars, is released under the MIT license and runs locally with uvx openosint.

OpenOSINT An OSINT (Open Source Intelligence) agent for security researchers and analysts: 21 investigation tools behind a natural-language interface, plus an MCP (Model Context Protocol) server so any MCP-compatible AI client can drive them directly. Use it as a REPL, CLI, MCP server, or browser Web UI. The AI issues hard-stop tool calls; your code executes the real binary — hallucinated findings are structurally impossible.
