Tools (6)

  • list_search_engines – co potrafi serwer
  • search_ahmia – wyszukiwarka clearnet/onion Ahmii
  • search_dark_web – multi-engine (Ahmia + Torch)
  • fetch_onion – pobiera tekst .onion przez Tor
  • check_onion_status – ping .onion
  • extract_onion_links – regex v2/v3 .onion z tekstu

Szybki start lokalnie

# 1. Zależności
pip install -r requirements.txt

# 2. Tor (do narzędzi .onion)
sudo systemctl start tor    # albo: tor &

# 3. Serwer
python standalone_server.py --host 0.0.0.0 --port 8080

# 4. Smoke test
curl http://127.0.0.1:8080/health

Endpoint MCP dla klientów Streamable HTTP: http://127.0.0.1:8080/mcp.

Deploy na Gumloopa

  1. Zbuduj obraz: docker build -t onion-search-mcp .
  2. Wystaw publiczne HTTPS (Render, Fly.io, Railway, AWS App Runner, Cloudflare Tunnel… cokolwiek). HTTP jest blokowany przez Gumloop.
  3. (opcjonalnie) ustaw MCP_BEARER_TOKEN=<sekret> żeby wymagać auth.
  4. W Gumloop: Settings → Credentials → MCP Server → Add credential
    • URL: https://<twoj-host>/mcp
    • Access Token: ten sam MCP_BEARER_TOKEN
  5. Add tools → MCP Server → Custom → onion-search na agencie.

Integracja z głównym repo guMCP

Folder src/servers/onion-search/ jest 1:1 zgodny z konwencją guMCP – wystarczy go skopiować do swojego forka:

cp -r src/servers/onion-search /path/to/guMCP/src/servers/
python src/servers/local.py --server onion-search --user-id local

Auto-discovery w remote.py::discover_servers() znajdzie folder automatycznie.

Bezpieczeństwo

  • Cały ruch do .onion idzie przez Tor SOCKS5 (TOR_SOCKS_PROXY).
  • Domyślnie Ahmia uderzana jest po clearnet (HTTPS, bez Tora) – szybkie i bezpieczne.
  • Ahmia filtruje CSAM; Torch/Haystak – nie. Stosuj odpowiednie filtry po stronie wywołującego.
  • Standalone server obsługuje Bearer-token (MCP_BEARER_TOKEN).
