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?

ClaudeClaude CodeCursorVS CodeChatGPT

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",

        "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.

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?

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.

The same commands are what the skill runs for an agent. All of them are in the CLI reference.

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.

	Prompt-only OSINT skills	SpiderFoot	OpenOSINT
What runs the lookups	Nothing: the skill is instructions, and the agent improvises	Its own 200+ modules	Python tools shipped with it
Breadth	Whatever the agent can reach	Much broader: 200+ modules and a correlation engine, per its README	A focused tool set
Built to be driven by an agent	Yes, that is the format	Web UI or CLI, per its README	Agent Skill, Claude Code plugin, MCP server, CLI and web UI
Passive/noisy labels, off by default	No	Not claimed here	Yes, per tool
License	Varies	MIT	MIT

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.

Tool	Source	Level	Key needed
`search_dns`	dnspython (built-in)	passive	No
`search_rdap`	RDAP (IANA bootstrap)	passive	No
`search_whois`	python-whois	passive	No
`search_ip`	ipinfo.io	passive	Optional
`search_ip2location`	IP2Location API (sponsored)	passive	Required
`search_gdelt_geo`	GDELT 15-minute GKG feed	passive	No
`generate_dorks`	built-in	passive	No
`search_paste`	psbdmp.ws	passive	No
`search_github`	GitHub REST API	passive	Optional
`search_breach`	HaveIBeenPwned API	passive	Required
`search_shodan`	Shodan API	passive	Required
`search_censys`	Censys API	passive	Required
`search_virustotal`	VirusTotal API	passive	Required
`search_abuseipdb`	AbuseIPDB v2 API	passive	Required
`search_dorks_live`	Bright Data SERP API¹	passive	Required
`search_footprint`	Bright Data SERP API¹	passive	Required
`scrape_url`	Bright Data Web Unlocker¹	touches target	Required
`search_username`	sherlock	noisy	No
`search_email`	holehe	noisy	No
`search_domain`	sublist3r	noisy	No
`search_phone`	phoneinfoga	unverified	No

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.

Level	Meaning
passive	Queries third-party sources or computes locally; nothing is sent to the target's own infrastructure (standard DNS goes through your resolver)
touches target	The target's infrastructure can see the request
noisy	High request volume; expect rate limits, blocks and alerts
unverified	Network behavior not yet confirmed by a traffic capture; treated as non-passive
inherits	A 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.
