OSINT Toolkit MCP server

The MCP-OSINT server performs various OSINT (Open Source Intelligence) tasks by leveraging common network reconnaissance tools. It provides a unified interface for performing WHOIS lookups, network scans, DNS reconnaissance, and domain typosquatting checks to assist with security assessment and intelligence gathering.

Installation

Installing via Smithery

You can quickly install the MCP-OSINT server for Claude Desktop using Smithery:

npx -y @smithery/cli install mcp-osint --client claude

Manual Installation

If you prefer to install manually, you'll need to ensure the following prerequisites are installed on your system:

• whois
• nmap
• dnsrecon
• dnstwist
• dig
• host

Capabilities

WHOIS Lookup

Retrieves domain registration information including owner, registrar, and expiration dates.

Nmap Scanning

Performs fast network scans to discover open ports and running services on target systems.

DNS Reconnaissance

Gathers comprehensive DNS information using multiple tools:

• dnsrecon: Collects DNS records and attempts zone transfers
• dig: Queries detailed DNS records
• host: Retrieves basic DNS host information

Domain Typosquatting Detection

Uses dnstwist to identify potential domain permutations that could be used for phishing or brand impersonation.

Combined OSINT Overview

Executes all tools concurrently to provide a comprehensive intelligence report on a target.

Usage Examples

Basic OSINT Commands

Here are examples of how to use the MCP-OSINT server's capabilities:

WHOIS Lookup

Get me the WHOIS information for example.com

Network Scanning

Perform a fast Nmap scan on 192.168.1.1

DNS Information Gathering

Run DNS reconnaissance on mytarget.com

Domain Typosquatting Check

Check for domain typos using DNSTwist on mytarget.com

Detailed DNS Records

Show me all DNS records for example.com using dig

Host Information

Fetch host lookup details for example.com

Comprehensive Analysis

To run all OSINT tools against a single target for a full overview:

Give me an OSINT overview for example.com

This will execute all the available tools in parallel and provide a consolidated report of findings.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mcp-osint" '{"command":"npx","args":["-y","mcp-osint"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "mcp-osint": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-osint"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "mcp-osint": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-osint"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
