What your AI can do with Open Agent Utility Index
Real prompts you can type the moment it's connected — no setup, no docs to read.
“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.”
“Use “normalize-url”: Return origin, host, and path for a URL. Query and fragment are dropped.”
How secure is the Open Agent Utility Index MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Open Agent Utility Index holds up.
Official endpoint
Operated by Open Agent Utility Index (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 Open Agent Utility Index adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

Is there an official Open Agent Utility Index MCP server?
