OSINT tools meet LLMs, and someone made a list of the glue

What it does

This is an awesome-list, not a product: a curated catalog of MCP servers that expose OSINT capabilities to LLM clients like Claude, Cursor and Windsurf. The pitch is that instead of memorizing CLI flags for Sherlock, Maigret or theHarvester, you ask an assistant in plain language and it runs the tools and assembles a report. Entries are organized by discipline — SOCMINT, network scanning, web scraping, company intelligence, threat intel, geospatial, blockchain, and more — with a legend marking what’s open source, free-tier, or paid.

The interesting bit

The list quietly documents a shift: OSINT is becoming a conversation. Several entries are aggregator servers that wrap a dozen classic CLIs behind one MCP interface (e.g. osint-toolbox-mcp bundles 17 tools from Sherlock to PhoneInfoga), while others go the other direction — hosted, metered services with MCP endpoints and no local install at all. The free/paid split is roughly half and half, which tells you where the money is.

Key highlights

• Covers 11 categories, from social media and network scanning to blockchain and market intelligence.
• Notable aggregators: osint-tools-mcp-server (7 CLIs) and osint-toolbox-mcp (12 tools, no API keys).
• Company-intelligence section is surprisingly deep — SEC EDGAR, UK Companies House, 27 national registries, African registries via Fylings.
• Honest pricing legend: 📦 open source, 🆓 free tier, 💰 paid, so you know before you click.
• Pull requests welcome — it’s a living index, currently around 500 stars.

Caveats

• It’s a list of links with one-line blurbs; quality of the linked servers varies and isn’t vetted beyond curation.
• Several entries are commercial services using the list for visibility — the blurbs read like vendor copy in places.

Verdict

Worth a bookmark if you do OSINT-adjacent work and want your LLM client to actually run the tools instead of describing them. If you were hoping for a single installable OSINT toolkit, this is the map, not the territory.
