Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “time_now”: The current time: Unix epoch in seconds and milliseconds, ISO 8601, and the local wall-clock time in a given IANA time zone with its current.”
“Use “convert_timestamp”: Convert a Unix timestamp (seconds or milliseconds; auto-detected unless unit is given) to a human-readable date in a time zone, with ISO 860.”
“Use “parse_datetime”: Parse a date/time string (ISO 8601, RFC 2822, HTTP date, SQL "YYYY-MM-DD HH:mm:ss", or a Unix timestamp) into a Unix timestamp and a normali.”
“Use “convert_timezone”: Convert a wall-clock date/time from one IANA time zone to another, correctly across daylight-saving transitions. Returns both sides with off.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Epoch Calculator holds up.
Operated by Epoch Calculator (epochcalc.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 Epoch Calculator 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 Epoch Calculator in the gate directory. No sign-in needed.
Epoch Calculator's tools are live in every AI client you've connected — with rules and logging built in.

Fetched live from the official endpoint and re-checked daily by gate — not marketing copy.

cron_next_runs — Explain a 5- or 6-field cron expression in plain English and list its next run times in a time zone (as ISO 8601 and Unix timestamps). Use t
days_until — Countdown to a holiday or to a date: days, hours and minutes remaining, and the next occurrence date. Pass an event slug (e.g. "christmas",
https://epochcalc.com/mcpYes — Epoch Calculator operates its own remote MCP server at epochcalc.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
Add gate's gateway URL to your AI client once, then pick Epoch Calculator in the directory. No account or sign-in is needed. From then on, Epoch Calculator's tools are available in every client you've connected to gate.
No. Epoch Calculator runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Yes — you can get started with gate for free and connect Epoch Calculator in minutes. No credit card required.
Every server below works through the same gateway URL — connect once, add tools anytime.
