What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

now
Current instant plus wall-clock time in an IANA timezone (e.g. America/Chicago). Includes offset and DST flag.
convert
Convert an ISO-8601 instant (or naive local with from=) between IANA zones, handling DST.
resolve_expression
Resolve expressions like "next Tuesday 3pm", "tomorrow 9am", or "in 2 business days" in a timezone.
is_business_day
Whether a YYYY-MM-DD date is a business day in a country (weekend + Nager.Date public holidays).
add_business_days
Add N business days to a start date, skipping weekends and public holidays.

Common questions

Is ChronoGate safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

ChronoGate

Timezone and business-day truth for scheduling agents. LLMs guess at "now", DST and holidays; ChronoGate answers authoritatively: current time in any IANA zone, DST-safe conversion, relative expressions ("next Tuesday 3pm", "in 3 business days"), and public-holiday-aware business days for 100+ countries (via Nager.Date).

Remote MCP: https://chronogate-self.vercel.app/mcp (Streamable HTTP, JSON-RPC, protocol 2025-06-18, stateless)
Docs for agents: https://chronogate-self.vercel.app/llms.txt
Free tier: 200 calls/day per IP, no API key. Over the limit returns HTTP 402 (with buy link); resets 00:00 UTC. Paid tier coming.

MCP tools

Tool	What it does
`now`	Current instant + wall-clock time, offset and DST flag in an IANA zone
`convert`	Convert an ISO timestamp between zones, DST-safe
`resolve_expression`	Resolve "tomorrow 9am", "next Tuesday 3pm", "in N business days" to an exact instant
`is_business_day`	Weekend + public-holiday check for a date and country
`add_business_days`	Add N business days to a date, skipping weekends and holidays

Notes

Holidays come from the public Nager.Date API; if it's unavailable, weekend logic still works (holiday_source: "unavailable").
