OpenOSINT

An OSINT (Open Source Intelligence) agent for security researchers and analysts: 20 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.

Usage

Start the REPL and investigate any target — the agent decides which tools to run and chains them on findings:

openosint > investigate target@example.com

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

  -> search_breach('target@example.com')
  Found in 2 breaches: LinkedIn (2016), Adobe (2013)

  -> search_username('johndoe99')   <- pivoted from email findings
  Found: GitHub, Reddit, Twitter

  Report saved -> reports/2026-05-11_14-32-11_report.md

Graph module (optional)

An additive FollowTheMoney entity graph — statement-level provenance, an append-only store, non-destructive same_as deduplication, and a human review queue — sits alongside the tools above without changing anything about them. Opt in with pip install "openosint[graph]" (Python 3.10+) or "openosint[graph-dedup]" (adds same_as scoring, needs Python 3.11+), then use it via three MCP tools: graph_export, graph_neighbors, graph_review_candidates. See docs/graph.md for the full guide and a worked example.

The same workflow is shown end to end — including the .ftm export that passes ftm validate — in the terminal demo in docs/graph.md; the web UI walkthrough is the demo at the top of this README.

Interfaces

Web UI

pip install "openosint[web]"
openosint web
# Opens http://localhost:8080 automatically

Try the live demo → — bring your own Anthropic / OpenRouter / Ollama key, no signup.

# Fully local (no API key) — requires Ollama runtime: https://ollama.com
ollama pull llama3.2
openosint web
# Settings -> Ollama (local) -> model: llama3.2

# Settings -> OpenAI API

Breaking change (v2.28+): key usage now follows bind address, not an env var. Bound to 127.0.0.1/localhost (the default) — no change: keys in your .env work as before. Bound to any other interface (--host 0.0.0.0, which already requires --allow-remote) — the web UI never uses a key from your environment to serve a request; every caller must supply their own, and breach lookups (search_breach) are disabled outright. This applies regardless of any env var, including OPENOSINT_DEMO_MODE, which can only add restriction, never remove it. If you were exposing the web UI on a LAN with your own keys and no per-caller auth in front of it, that access pattern no longer works.

Running behind a reverse proxy? A loopback bind (127.0.0.1) only means the OS accepted the connection from this machine — it says nothing about who can reach it if something in front (nginx, Caddy, a Docker/K8s sidecar, a tunnel) forwards requests to it from elsewhere. By default, a request that carries proxy-forwarding headers (X-Forwarded-For, X-Forwarded-Proto, X-Forwarded-Host, Forwarded, CF-Connecting-IP) is treated exactly like a non-loopback bind: your local keys are never used, breach lookups are blocked, and the caller is told why. If you deliberately serve this through a reverse proxy and want it to behave like a normal local instance for requests relayed by that proxy, set OPENOSINT_TRUSTED_PROXY=true. This is a separate variable from the existing TRUSTED_PROXY (which only affects which IP a rate-limit bucket is attributed to — a low-stakes, already-loosely-scoped setting some self-hosters already have on). Reusing that flag here would have silently upgraded an existing rate-limit-only configuration into one that also permits credentialed access, without asking. OPENOSINT_TRUSTED_PROXY gets its own explicit opt-in for that reason. Setting it does not blindly trust the forwarded headers' content — internally inconsistent values (e.g. two disagreeing X-Forwarded-Proto values on one request) are still treated as public regardless. Setting OPENOSINT_TRUSTED_PROXY=true means you are choosing to serve credentialed lookups to whoever your reverse proxy relays to this instance — you are the controller for their queries, the same way OpenOSINT Cloud is for its customers. Put real authentication in front of it if "whoever the proxy relays" is broader than you intend.

Live Documentation

Full per-tool reference, CLI flags, and configuration options at openosint.tech.

MCP Server

Expose all 20 OpenOSINT tools to any MCP-compatible AI client. Once connected, Claude can natively invoke all 20 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"],
      "env": { "OPENOSINT_ENV_FILE": "/absolute/path/to/your/.env" }
    }
  }
}

MCP hosts launch this server with a cwd that has nothing to do with your .env (often your home directory, or wherever the host itself runs from). The server falls back to a repo-root .env for a source checkout, then an upward search from that arbitrary cwd — but for a pip installed openosint, neither is reliable. Setting OPENOSINT_ENV_FILE in the client's own env block above, as shown, is the one option guaranteed to work regardless of how the host launches the process.

Agentic use via Claude Code:

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

Installation

# From PyPI (recommended)
pip install openosint

# Updating
pip install --upgrade openosint

# 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. All other tools remain operational.

Optional Python packages:

Configuration

Copy .env.example to .env and fill in your keys. .env is read from the directory you run openosint from (searched upward, like git finds .git) — it does not need to be at any particular "project root", and a regular pip install works the same way as running from a source checkout. Set OPENOSINT_ENV_FILE=/path/to/.env to point at an explicit file instead (useful for the MCP server, which is launched by its host with an arbitrary working directory). A real environment variable always takes priority over a value in .env.

Required below means required for that specific tool to run, not for openosint itself — the app starts and every key-less tool works with zero configuration.

On a fresh install with no keys at all, these still work: generate_dorks, search_dns, search_whois, search_domain, search_email, search_username, search_paste, search_phone, search_ip (rate-limited), search_github (rate-limited), and search_gdelt_geo.

CLI Reference

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.

Integrations

Limitations

• Authorized use only. OpenOSINT queries public and semi-public sources. It does not bypass authentication, exploit systems, or access anything you aren't already entitled to see. You are responsible for complying with the law and the terms of service of every source you query. See DISCLAIMER.md.
• No aggregation guarantees. Each tool reports what its upstream source currently returns. A negative result (no breach found, no accounts found) means the source didn't report a match — not that no exposure exists.
• Most tools depend on third-party services you don't control. Nine of the 20 tools hard-require an API key and are subject to that provider's uptime, rate limits, and pricing (Shodan, VirusTotal, Censys, AbuseIPDB, IP2Location, HaveIBeenPwned, and the three Bright Data–backed tools). Free tiers are small; heavy use requires a paid plan with the provider, not with OpenOSINT.
• Local binaries are unsandboxed subprocesses. holehe, sherlock, sublist3r, and phoneinfoga run as external processes on your machine. Keep them updated yourself; OpenOSINT does not patch or vet them.
• The entity graph module (openosint[graph]) is additive, not authoritative. same_as links are scored candidates for human review, not verified identity matches — see docs/graph.md.
• The AI agent can only call the 20 tools above. It cannot browse the open web freely, run arbitrary code, or invent data — every finding comes from a real tool call, but the agent's tool selection can still be wrong or incomplete for a given target.
