Osint Tools

OSINT Tools

Overview

External tools for open-source intelligence gathering, all located in convex/tools/:

All tool files follow the same pattern: internalAction with env var guard at the top.

Maigret

Architecture

Maigret is a Python CLI tool. Since Convex actions run in the cloud, we run a local FastAPI sidecar that wraps the CLI and exposes it as HTTP.

Convex action -> HTTP GET -> sidecar/search?username=X&top_sites=100 -> Maigret CLI -> JSON

Sidecar Server

Located in sidecar/server.py:

• Framework: FastAPI with CORS middleware (allows all origins)
• Endpoints:
  • GET /search?username=X&top_sites=100&timeout=10 — Single username search
  • GET /batch?usernames=X,Y,Z&top_sites=50 — Parallel batch search (max 5)
  • GET /health — Health check (verifies Maigret is installed)
  • GET /info — Maigret version and sidecar info
• Process: Spawns Maigret as a subprocess with asyncio.create_subprocess_exec
• Timeout: 120 seconds per search subprocess
• Output: Writes to temp directory via --folderoutput, parses report_{username}_simple.json

Maigret CLI Flags

maigret {username} \
  -J simple \                # Simplified JSON output (capital J)
  --folderoutput {dir} \     # Output directory for reports
  --top-sites 100 \          # Only check top N sites (max 500)
  --timeout 10 \             # Per-site timeout (max 30)
  --no-color \               # Clean output
  --no-progressbar           # No progress bar (cleaner logs)

Response Format

{
  "username": "johndoe123",
  "count": 8,
  "results": {
    "github": { "url": "https://github.com/johndoe123", "site_name": "GitHub", "category": "professional", "fullname": "John Doe", "location": "Fremont" },
    "telegram": { "url": "https://t.me/johndoe123", "site_name": "Telegram", "category": "messaging", "fullname": "John Doe", "bio": "..." },
    "tiktok": { "url": "https://tiktok.com/@johndoe123", "site_name": "TikTok", "category": "social" }
  },
  "categories": { "professional": 1, "messaging": 1, "social": 1 }
}

Convex Integration

convex/tools/maigret.ts — three exported functions:

const url = `${SIDECAR_URL}/search?username=${encodeURIComponent(args.username)}&top_sites=${topSites}`;
const res = await fetch(url, {
  signal: AbortSignal.timeout(130_000), // slightly above sidecar's 120s
});

Retry logic: Tries up to 2 times with 2s backoff between attempts.

Non-blocking: If the sidecar is down after 2 attempts, returns { error: "...", results: {} } instead of throwing. The investigation continues without Maigret leads.

Running the Sidecar

cd sidecar
pip install -r requirements.txt   # maigret, fastapi, uvicorn[standard]
python server.py                   # -> http://localhost:8000

Brave Search

convex/tools/braveSearch.ts — search internalAction.

Fast web lookups via the Brave Search API. Used by the web_search orchestrator tool. Returns titles, URLs, and snippets.

Browser Use

convex/tools/browserUse.ts — See the browser-automation skill for full documentation.

Cloud browser automation via Browser Use v3 API. Exports runTask, getSession, stopSession.

Picarta

convex/tools/picarta.ts — localize internalAction.

AI photo geolocation. Takes an image URL, returns lat/lon/confidence predictions. Used by the geo_locate orchestrator tool. Free tier: 100 calls/month.

Intelligence X

convex/tools/intelx.ts — search internalAction.

Dark web and data breach search via the IntelX API. Only available in extreme mode. Uses a polling pattern: submit search, wait 2s intervals, fetch results.

Reverse Image Search

convex/tools/reverseImageSearch.ts — search internalAction.

Google Lens reverse image search via SerpAPI. Takes an image URL, returns visual matches with titles, links, and thumbnails.

Common Tool Pattern

All tools follow the same structure:

import { v } from "convex/values";
import { internalAction } from "../_generated/server";

export const someAction = internalAction({
  args: { /* ... */ },
  handler: async (_, args) => {
    const apiKey = process.env.SOME_API_KEY;
    if (!apiKey) throw new Error("SOME_API_KEY not set");
    // fetch external API...
  },
});

Orchestrator calls tools via: await ctx.runAction(internal.tools.<name>.<function>, { ... })
