Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “qr_code”: Make a QR code for any text, URL, Solana Pay / wallet address or Wi-Fi login — as a PNG (base64 data URL) or SVG, with size, margin, colours.”
“Use “hash_encode”: Hash data (SHA-256/512, SHA3, Keccak-256, BLAKE2, MD5, SHA-1, RIPEMD-160, HMAC) and convert between utf8, hex, base64, base64url and base58.”
“Use “json_schema_validate”: Validate JSON data against a JSON Schema (draft-07/2019-09/2020-12, formats like email/uri/date-time) and get every error with its exact pat.”
“Use “cron_explain”: Explain a cron expression in plain English and list its next N run times in any time zone — catch a schedule mistake before it fires at 3 am.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MAD Synapse · Utils holds up.
gate scanned 10 tools on Sep 30, 2026. A few things are worth a look before you connect.
Operated by MAD Synapse · Utils (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 · Utils 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 · Utils in the gate directory. No sign-in needed.
MAD Synapse · Utils's tools are live in every AI client you've connected — with rules and logging built in.
