Overview

Description from the maker (original English)

AI-powered OSINT agent & MCP server. 21 tools: email, breach, IP, WHOIS, DNS, Shodan, GitHub & more.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Chat & email
  • You need to fill in: ANTHROPIC_API_KEY, HIBP_API_KEY, IPINFO_TOKEN, IP2LOCATION_API_KEY, ABUSEIPDB_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: ANTHROPIC_API_KEY, HIBP_API_KEY, IPINFO_TOKEN, IP2LOCATION_API_KEY, ABUSEIPDB_API_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • PyPIPython’s uv installed (for the uvx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "openosint": {
      "command": "uvx",
      "args": [
        "openosint"
      ],
      "env": {
        "ANTHROPIC_API_KEY": "your-value",
        "HIBP_API_KEY": "your-value",
        "IPINFO_TOKEN": "your-value",
        "IP2LOCATION_API_KEY": "your-value",
        "ABUSEIPDB_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add openosint --env ANTHROPIC_API_KEY=your-value --env HIBP_API_KEY=your-value --env IPINFO_TOKEN=your-value --env IP2LOCATION_API_KEY=your-value --env ABUSEIPDB_API_KEY=your-value -- uvx openosint

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "openosint": {
      "command": "uvx",
      "args": [
        "openosint"
      ],
      "env": {
        "ANTHROPIC_API_KEY": "your-value",
        "HIBP_API_KEY": "your-value",
        "IPINFO_TOKEN": "your-value",
        "IP2LOCATION_API_KEY": "your-value",
        "ABUSEIPDB_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "openosint": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "openosint"
      ],
      "env": {
        "ANTHROPIC_API_KEY": "your-value",
        "HIBP_API_KEY": "your-value",
        "IPINFO_TOKEN": "your-value",
        "IP2LOCATION_API_KEY": "your-value",
        "ABUSEIPDB_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • ANTHROPIC_API_KEY secret required env
    Anthropic API key — required for the AI agent REPL
  • HIBP_API_KEY secret env
    HaveIBeenPwned API key for breach detection (search_breach tool)
  • IPINFO_TOKEN secret env
    ipinfo.io token for higher IP lookup rate limits (search_ip tool)
  • IP2LOCATION_API_KEY secret env
    IP2Location API key for enhanced IP intelligence (search_ip2location tool)
  • ABUSEIPDB_API_KEY secret env
    AbuseIPDB API key for IP abuse reputation checks (search_abuseipdb tool)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is OpenOSINT safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ANTHROPIC_API_KEY, HIBP_API_KEY, IPINFO_TOKEN, IP2LOCATION_API_KEY, ABUSEIPDB_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.38.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

README from the maker

mcp-name: io.github.OpenOSINT/openosint

OpenOSINT The OSINT toolkit for AI agents: Agent Skill, MCP server and CLI. Passive by default, no API keys needed to start, and every finding cites the tool call that produced it.

*A real Claude Code session, nothing mocked: install the plugin and run a passive recon on example.com. Sharper MP4.*

Quickstart

Needs uv. No API keys for the default flow.

Claude Code plugin (skills plus a passive MCP server):

/plugin marketplace add OpenOSINT/OpenOSINT

/plugin install openosint@openosint /openosint:osint example.com

Any agent (Codex, Gemini CLI, Cursor and other Agent Skills clients):

npx skills add OpenOSINT/OpenOSINT

MCP server or pip (other clients):

claude mcp add openosint -- uvx --from openosint openosint-mcp

pip install openosint && openosint exposure example.com

OpenOSINT Cloud

The same engine as a hosted chat: ask about a domain, an IP address or a company. Every answer shows which public sources were checked, when, and a source on every claim. No install, no API keys.

Try it: 10 free messages

What you can do

Real output, captured 2026-11-04 on v2.37.0 and trimmed. None of these commands needs an API key or an AI provider.

Why OpenOSINT

  • Real tool executions. Tools are Python code; only their actual output reaches the model.
  • Provenance. Every finding is shown with the tool call that produced it. AI summaries are leads to verify, not proof.
  • Passive by default, with noise labels. Tools that touch the target or are noisy are not even offered to the agent until you opt in.
  • Works with no keys. exposure, dns, rdap, whois, ip, gdelt and dorks need no account.

SpiderFoot is the better choice when you want a large standalone scanner. OpenOSINT is for agents that need a small set of real, labelled tools.

Tools

Level is the noise label: passive tools are on by default; anything else needs --allow-active. Per-tool docs: openosint.tech/tools.

Sherlock, holehe, sublist3r and phoneinfoga are wrapped as local binaries; install them yourself and enable active tools to use them.

Setting up the three Bright Data tools: Using OpenOSINT with Bright Data.

Passive by default

Agents and MCP clients are only offered tools that query third-party data sources or compute locally. Anything that touches the target or sends many requests from your IP is off until you opt in, and is not listed in an MCP client's tools/list at all.

LevelMeaning
passiveQueries third-party sources or computes locally; nothing is sent to the target's own infrastructure (standard DNS goes through your resolver)
touches targetThe target's infrastructure can see the request
noisyHigh request volume; expect rate limits, blocks and alerts
unverifiedNetwork behavior not yet confirmed by a traffic capture; treated as non-passive
inheritsA fan-out tool that only runs what the current mode allows

Enable active tools with openosint --allow-active …, OPENOSINT_ALLOW_ACTIVE=1, Web UI Settings (loopback only), or openosint-mcp --allow-active. Passive is not private: every service you query sees the query. Per-tool "what it sends" table and the tool-call cap: Safety.
