Overview

AI-generated overview

Runs OSINT.SX people and account lookups from an assistant: one search across all sources, plus Google, Microsoft, Epic, X, Steam, Instagram and TikTok tools.

What you can do
  • Search an email, phone number, username or full name across every OSINT.SX source and list the sites where it is registered
  • Look up Google accounts and Gaia IDs, Microsoft accounts and CIDs, and Epic Games accounts by name, ID or linked platform
  • Retrieve archived profile history for X and Steam, including earlier usernames, names, bios and avatars
  • Trace the account behind an Instagram or TikTok share link copied in the app
  • Tune calls with a longer wait, inclusion of alerting sources, and raw source output
When to use it
Useful when an assistant needs to check where an email, phone, username or name appears online, or to pull archived account history and platform account records, with results returned in the chat instead of a separate web session.
Requirements
Runs locally via npx (npm package osintsx-mcp) and needs Node.js 20.3 or newer. Requires an OSINT.SX API key supplied in the OSINTSX_API_KEY environment variable; an optional OSINTSX_API_URL overrides the default API endpoint. Network access to OSINT.SX is required, and searches consume paid credits.
Before you install
Every search costs 1 credit from your own API key, so usage spends money; a single-platform tool may still consume its credit after the call is cut short. Searches cover personal data about people, and some sources may notify the person being looked up unless they are excluded. Only search people you have a lawful reason to look into.

Installation

In SourceWeft

  1. Open OSINT.SX in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

osintsx-mcp

An MCP server for the OSINT.SX API.

It lets an AI assistant such as Claude, Cursor or VS Code run OSINT.SX searches for you. It can check an email, phone number, username or name against every source at once, or use one of the single-platform tools.

It runs on your own API key. Each search costs what it costs on the site: 1 credit. A search that finds nothing because most sources failed gives the credit back. Tool searches cost nothing when they find nothing.

Setup

  1. Make an API key at https://osint.sx/keys.
  2. Add the server to your MCP client with that key.

Claude Desktop, Cursor and most clients (claude_desktop_config.json, .cursor/mcp.json):

json
{  "mcpServers": {    "osintsx": {      "command": "npx",      "args": ["-y", "osintsx-mcp"],      "env": { "OSINTSX_API_KEY": "YOUR_API_KEY" }    }  }}

Claude Code:

bash
claude mcp add osintsx --env OSINTSX_API_KEY=YOUR_API_KEY -- npx -y osintsx-mcp

Node.js 20.3 or newer is required.

Tools

ToolWhat it does
searchChecks an email, phone number (+E.164), username or full name against every source, and returns each site where it's registered with the details that site shows.
google_account_lookupFinds Google accounts and Gaia IDs by email, name or domain, or looks one up by Gaia ID.
microsoft_account_lookupFinds Microsoft accounts by email, name or domain, or looks one up by CID.
epic_games_lookupFinds Epic Games accounts by display name, account ID, or the username on a linked platform.
twitter_historyLooks up an X profile's archived history: earlier usernames, names, bios, locations and pictures.
steam_historyLooks up a Steam profile's archived history: earlier names, custom URLs and avatars, and other accounts that held the same custom URL.
instagram_share_traceFinds the account that shared an Instagram link copied from the app.
tiktok_share_traceFinds the account that shared a TikTok short link copied from the app.

A call waits up to 50 seconds by default, then returns whatever has come in, and the result says it was cut short. For search, the sources that hadn't answered are cancelled. A single-platform tool keeps running on OSINT.SX after the cut-off, so its credit may still be used. 50 seconds keeps the call under the 60-second timeout many MCP clients use, and in testing almost every source answered within that time.

If your client allows longer calls, set max_wait_seconds (up to 600). Clients that support progress notifications show progress while a search runs.

By default, search leaves out sources that may notify the person. Set include_alerting_sources to include them.

Replies are kept under about 48 KB, so they fit what MCP clients accept. If there are more results than that, the reply says how many were left out. The Google, Microsoft, Epic and share-trace tools return each result's main fields; set include_raw to get everything the source sent.
