What your AI can do with Julian day number
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.”
How secure is the Julian day number MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Julian day number holds up.
Security grade A
gate scanned 31 tools on Oct 18, 2026 for prompt injection and risky tool definitions — nothing to flag.
Official endpoint
Operated by Julian day number (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 Julian day number adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
