Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “parse_date_query”: Parses queries like "90 business days from today in uganda" into a normalized operation, answers it, and returns the auditable receipt. Ambi.”
“Use “add_days”: The date N whole calendar days after a date (exclusive counting: the start date is day 0).”
“Use “subtract_days”: The date N whole calendar days before a date.”
“Use “days_between”: Signed whole calendar days from one date to another, midnight to midnight, endpoints exclusive (the gap).”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how tilwhen date engine holds up.
Operated by tilwhen date engine (tilwhen.com) 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 tilwhen date engine 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 tilwhen date engine in the gate directory. No sign-in needed.
tilwhen date engine's tools are live in every AI client you've connected — with rules and logging built in.
