Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MAD Synapse · World holds up.
gate scanned 8 tools on Oct 4, 2026 for prompt injection and risky tool definitions — nothing to flag.
Operated by MAD Synapse · World (maddegen.art) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If MAD Synapse · World adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose MAD Synapse · World in the gate directory. No sign-in needed.
MAD Synapse · World's tools are live in every AI client you've connected — with rules and logging built in.
Free to start · No credit card · No hosting needed
