26 free OSINT tools as MCP tools for AI agents one tool to installs and use everything

内容

osint-mcp — Free OSINT Tools as MCP Tools for AI Agents

One command. 26 free OSINT tools. Any AI agent.

uvx osint-mcp   # installs everything and starts the MCP server

What is osint-mcp?

osint-mcp is a Python package that wraps 26 free OSINT (Open Source Intelligence) tools as MCP (Model Context Protocol) tools, giving AI agents like Claude, GPT-4, and any MCP-compatible agent the ability to perform real OSINT investigations directly from a conversation.

The problem it solves: Running OSINT tools traditionally requires installing a dozen separate binaries, writing glue scripts, and manually parsing outputs. osint-mcp automates the entire setup — it detects your OS, installs all tools via Homebrew / apt / Go / pip, and exposes them to your AI agent through a single MCP server.

Who it is for:

Security researchers and penetration testers who want AI-assisted reconnaissance
Developers building AI agents with security investigation capabilities
Bug bounty hunters automating initial footprinting
Threat intelligence analysts enriching IOCs (Indicators of Compromise)
Students learning OSINT with AI guidance

Key Features

26 free OSINT tools spanning network, domain, social media, email, web, phone, and secrets scanning
Single-command setup — uvx osint-mcp auto-installs all underlying tools on first run
MCP-native — works out of the box with Claude Desktop, any MCP client, or the Anthropic SDK
Zero-config for most tools — 15 tools work with no API key at all
Graceful degradation — tools with optional free API keys (Shodan, VirusTotal) work in reduced mode without them and tell you exactly how to enable full access
macOS + Linux support (Homebrew, apt, yum, Go, pip — all detected automatically)
Safe by default — passive recon only unless you explicitly call a port-scan or secrets-scan tool

One-Command Setup (Recommended)

uvx is the Python equivalent of npx — it installs the package in an isolated environment and runs it immediately. No pip install, no virtual environment setup needed.

uvx osint-mcp

On first run, this automatically:

Installs osint-mcp in an isolated Python environment
Detects your OS (macOS or Linux)
Installs all 26 OSINT tool binaries via Homebrew / apt / Go / uv pip
Starts the MCP server on stdio (ready for Claude Desktop or any MCP client)

On subsequent runs, it boots in under a second — tools are already installed.

Connect to Claude Desktop

Add one entry to your Claude Desktop config and you are done.

macOS — ~/Library/Application Support/Claude/claude_desktop_config.json
Linux — ~/.config/Claude/claude_desktop_config.json

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

Restart Claude Desktop. You will see 26 new OSINT tools available in the tool list.

Alternative: Traditional pip Install

If you prefer managing your own environment:

pip install osint-mcp

# Install all OSINT tool binaries
osint-mcp install

# Check what is available
osint-mcp status

# Start the MCP server
osint-mcp serve

How It Works

Claude Desktop / AI Agent
        │
        │  MCP (stdio)
        ▼
  osint-mcp server
        │
        ├── osint_whois        →  python-whois library
        ├── osint_port_scan    →  nmap binary (subprocess)
        ├── osint_subdomain_enum → subfinder binary
        ├── osint_cert_transparency → crt.sh public API (HTTP)
        ├── osint_shodan_host  →  Shodan REST API (optional key)
        ├── osint_virustotal   →  VirusTotal REST API (optional key)
        └── ... 20 more tools

Each tool is a BaseTool subclass. The registry auto-discovers all subclasses at startup and registers them with FastMCP. If a tool's binary is not installed, it returns a clear "not installed — run osint-mcp install" message instead of crashing.

Example AI Agent Conversations

Once connected to Claude Desktop, you can ask questions like:

"Investigate the domain example.com — find subdomains, check for data breaches on contact emails, and look it up on Shodan."

"Scan the GitHub repo github.com/org/repo for exposed secrets and API keys."

"Find all social media accounts associated with the username johndoe123."

"Check if the IP 1.2.3.4 is listed on Shodan and what ports are open."

"Look up the phone number +14155552671 and find what carrier and country it's registered to."

The agent automatically chains multiple tools, interprets the results, and presents a coherent investigation summary — no manual tool orchestration needed.

Frequently Asked Questions

Q: What is MCP (Model Context Protocol)?
A: MCP is an open standard by Anthropic that lets AI models call external tools in a structured, secure way. It is to AI agents what HTTP is to web browsers — a universal protocol for tool use. Learn more at modelcontextprotocol.io.

Q: Does osint-mcp work with AI agents other than Claude?
A: Yes. Any MCP-compatible client works — including OpenAI's agent framework (via MCP adapters), LangChain, LlamaIndex, and custom agents built with the Anthropic SDK. The server communicates over stdio using the standard MCP JSON-RPC protocol.

Q: Does it cost anything?
A: The package itself is free and open source. All 26 tools are free. Some tools (Shodan, VirusTotal) require a free API key registration for full functionality but offer a usable free tier.

Q: Is it safe? Will it run scans without my permission?
A: Passive tools (WHOIS, certificate transparency, breach databases, username search) run automatically. Active tools (port scanning with nmap, secret scanning with TruffleHog) only run when you or your agent explicitly calls them — and the server instructions remind the agent to confirm with the user before active scans.

Q: How is this different from running OSINT tools manually?
A: Three ways: (1) Installation — one command installs everything vs. hours of setup. (2) Integration — your AI agent can chain multiple tools automatically and interpret combined results. (3) Conversation — you describe what you want in plain English instead of memorising CLI flags.

Q: What is the difference between uvx and pip for installing osint-mcp?
A: uvx osint-mcp (recommended) runs the package in an isolated environment — no global pip install, no virtual environment setup. pip install osint-mcp installs it into your current environment. Both work; uvx is simpler and avoids dependency conflicts.

Q: Can I add my own OSINT tools?
A: Yes. Create a subclass of BaseTool in any file under src/osint_mcp/tools/<category>/ — the registry auto-discovers it on next start. No registration step needed. See tools/base.py for the interface.

Contributing

Contributions are welcome — new tools, better install recipes, bug fixes, and documentation improvements.

git clone https://github.com/rjn32s/osint-mcp
cd osint-mcp
uv venv && uv pip install -e ".[dev]"
osint-mcp status   # verify your setup

To add a new OSINT tool, create a BaseTool subclass in src/osint_mcp/tools/<category>/yourfile.py. The class needs name, description, input_schema, and an async run(args) method. The registry picks it up automatically.
