What is OpenOSINT?

OpenOSINT is an AI agent for Open Source Intelligence with three interfaces: an interactive terminal REPL, a direct CLI, and an MCP server exposable to Claude Code, Claude Desktop, or any MCP-compatible client — plus a browser-based Web UI added in v2.12.0. The AI layer uses Anthropic's native tool use API (or a local Ollama model): the model issues hard stops when it needs a tool, your code executes the real binary, the actual output goes back — hallucination in tool results is structurally impossible.

Features

• AI tool chaining — the agent decides which of 16 tools to run, chains them based on findings, and compiles a structured report

• 16 modular tools covering email, username, breach, WHOIS, IP, subdomain, dorks, paste, phone, Shodan, VirusTotal, Censys, IP2Location, AbuseIPDB, GitHub, and DNS

• Anthropic + Ollama — use Claude via API key or run fully offline with a local Ollama model

• MCP server — expose all tools natively to Claude Code and Claude Desktop

• Parallel execution — --parallel runs complementary tools concurrently via asyncio.gather()

• PDF + Markdown reports — auto-saved after every investigation; PDF export via reportlab

• Session history — all REPL sessions saved to ~/.openosint/history/; browse with openosint history

• Web UI — browser-based AI chat with streaming output, tool cards, and light/dark theme toggle

Installation

# Install from PyPI (recommended)
pip install openosint

# Or install from source
git clone https://github.com/OpenOSINT/OpenOSINT.git
cd OpenOSINT
pip install -e .

External binaries (must be in PATH):

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

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

openosint > investigate target@example.com

  -> generate_dorks('target@example.com')
  -> search_email('target@example.com')
  Found: Spotify, WordPress, Gravatar, Office365

All sessions are auto-saved to ~/.openosint/history/. Browse with openosint history.

Web UI

Introduced in v2.12.0:

openosint web
# Opens http://localhost:8080 automatically

Browser-based AI chat interface with streaming tool output, inline result cards, light/dark theme toggle, and Ollama support for fully local inference. No API key required when using Ollama.

# Install web extras
pip install "openosint[web]"
openosint web

# Use Ollama for fully local inference (no API key)
# Step 1: install the Ollama runtime (separate from the Python library)
#   macOS/Linux:  curl -fsSL https://ollama.com/install.sh | sh
#   Windows:      https://ollama.com/download/windows
# Step 2: start Ollama and pull a model
ollama serve          # start in a terminal (runs automatically as a service on some platforms)
ollama pull llama3.2  # download the model (~2 GB)
# Step 3: launch OpenOSINT and switch to Ollama
openosint web
# Settings -> Ollama (local) -> set model to llama3.2

MCP Server

Expose all 16 OpenOSINT tools to any MCP-compatible AI client. Once connected, Claude can natively invoke all 16 tools during conversations.

Claude Code:

claude mcp add openosint python /absolute/path/to/OpenOSINT/openosint/mcp_server.py
claude mcp list

Claude Desktop — add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "openosint": {
      "command": "python",
      "args": ["/absolute/path/to/OpenOSINT/openosint/mcp_server.py"]
    }
  }
}

Agentic use via Claude Code:

$ claude
> Investigate target@example.com. Trace any username found
  across other platforms and compile a full report.

Docker

# Build and run
docker compose up --build

# One-off command
docker compose run --rm openosint email target@example.com --json

Set ANTHROPIC_API_KEY (and optionally HIBP_API_KEY, IPINFO_TOKEN) in a .env file or export them before running docker compose. Reports are persisted to ./reports/ via a volume mount.

DigitalOcean App Platform: see .do/app.yaml for App Platform configuration.
