What your AI can do with 8 random hex chars
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “random-hex8”: 8 random hex chars.”
“Use “utc-time”: Current UTC timestamp.”
“Use “timezone”: Current time in a named IANA timezone.”
“Use “validate-json”: Check whether a body is valid JSON. The body is discarded.”
How secure is the 8 random hex chars MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how 8 random hex chars holds up.
Official endpoint
Operated by 8 random hex chars (workers.dev) 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 8 random hex chars adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
