kaggle-terminal

One-command SSH access into Kaggle notebooks over Cloudflare Tunnel.

Built to give my coding agents access to Kaggle GPUs. I couldn't find an existing way, and a shell is faster and more efficient than the Kaggle MCP.

Live demo Code

Stack

  • Python
  • Flask
  • PostgreSQL
  • Cloudflare Tunnel
  • SSH
  • Bash

How it works

  1. One command opens an SSH shell inside a Kaggle notebook, with its GPU.
  2. The connection runs through a Cloudflare Tunnel.
  3. The server only introduces the two ends. Your traffic and SSH keys never go through it.
  4. Run several notebooks at once, send single commands, or copy files with scp.
  5. A dashboard shows the GPU, CPU and RAM of each session.
  6. Logs in with SSH keys. Password login turns off once a key is added.

  3. Personal data is masked twice with Microsoft Presidio.
  4. A Router agent picks the intent and a Responder agent writes the answer.
  5. Each ticket ends as a CSV row: status, product area, request type, response and justification.

Subdomain Enumeration · Concurrent DNS Resolution · Attack Surface Mapping

How it works

  1. Three passes (find, resolve, probe), each saved to its own output file.
  2. Finds subdomains from eight passive sources, DNS brute force and AXFR zone-transfer attempts.
  3. Also uses subfinder, assetfinder or findomain when they are installed.
  4. Resolves names in parallel across public resolvers, with wildcard-DNS detection.
  5. Records the status code, redirect, page title and server header of each host.
  6. altdns-style permutations, and adjustable DNS and HTTP concurrency.
