What your AI can do with MGS Toolbox
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_encyclopedia”: Find metals, minerals, alchemical ingredients, potions and gems by name (case- and accent-insensitive; exact names first, then prefixes, the.”
“Use “get_entry”: The full data of one metal, mineral, ingredient, potion or gem by its id (from search_encyclopedia or list_entries): properties, lore, page.”
“Use “list_entries”: A page of one catalogue, filtered. Use it to answer "which minerals are cubic and gem-quality?", "legendary metals of the medieval era", "sw.”
“Use “random_entry”: One entry at random among those matching the filters: loot tables, "mineral of the day", a credible metal for a blacksmith, a foraging roll.”
How secure is the MGS Toolbox MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MGS Toolbox holds up.
Security grade A
gate scanned 12 tools on Sep 9, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by MGS Toolbox (michaelghelfistudios.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If MGS Toolbox adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
