NAME

openosint — AI-powered OSINT agent, MCP server, and CLI for Open Source Intelligence.

---

SYNOPSIS

openosint                          # interactive AI REPL (default)
openosint shell                    # same as above
openosint email ADDRESS [-t N]     # direct email scan, no AI
openosint username HANDLE [-t N]   # direct username scan, no AI
openosint [-v] [--api-key KEY]

---

DESCRIPTION

openosint is a modular OSINT framework with three interfaces:

Interactive REPL (default) — a Claude Code-style terminal where you type targets or questions in natural language. The AI agent decides which tools to run, chains them intelligently based on findings, and compiles a structured report.

Direct CLI — run individual OSINT tools without AI for scripting or quick lookups.

MCP Server — expose all 9 tools to any MCP-compatible AI client (Claude Code, Claude Desktop).

The framework is built on Python asyncio. All external binaries run as managed subprocesses with hard timeout enforcement. The AI layer uses the Anthropic native tool use API — the model issues hard stops when it needs a tool, your code executes it, the real output goes back. Hallucination in tool results is structurally impossible.

---

ARCHITECTURE

Layer	Path	Responsibility
Core tools	openosint/tools/	Async wrappers around external OSINT binaries and APIs. Stateless.
AI agent	openosint/agent.py	Anthropic tool use loop. Maintains conversation history.
REPL	openosint/repl.py	Interactive terminal session. prompt_toolkit + Rich.
MCP server	openosint/mcp_server.py	MCP tool schema exposure for AI clients.
CLI	openosint/cli.py	Entry point. Launches REPL or direct commands.

No layer imports from a layer above it.

---

INSTALLATION

Requires Python 3.10 or later.

git clone https://github.com/OpenOSINT/OpenOSINT.git
cd OpenOSINT
pip install -e .

Set your Anthropic API key:

export ANTHROPIC_API_KEY=sk-ant-...

External dependencies (must be present in PATH):

Binary	Purpose	Install
holehe	Email account enumeration	pip install holehe
sherlock	Username enumeration (300+ platforms)	pip install sherlock-project
sublist3r	Subdomain enumeration	pip install sublist3r
phoneinfoga	Phone number intelligence	Download binary

If a binary is absent, the corresponding tool returns a descriptive error string. All other tools remain operational.

Optional environment variables:

Variable	Tool	Purpose
HIBP_API_KEY	search_breach	HaveIBeenPwned API key — get one here
IPINFO_TOKEN	search_ip	ipinfo.io token for higher rate limits

---

INTERACTIVE REPL

Run openosint with no arguments to start the AI-powered REPL:

openosint ❯ investigate [e-mail]

  → generate_dorks('[e-mail]')
  → search_email('[e-mail]')
  ✓ Found: Spotify, WordPress, Gravatar, Office365

  → search_breach('[e-mail]')
  ✓ Found in 2 breaches: LinkedIn (2016), Adobe (2013)
