Settings → Apps & Connectors → Advanced settings → enable Developer mode, then create a connector with the endpoint URL above and No authentication. This server is read-only, so it works on plans where custom connectors are limited to read-only tools.
OpenClaw
Add the server to openclaw.json:
{
"mcp": {
"servers": {
"worldclockpro-time": {
"url": "https://worldclock.pro/mcp",
"transport": "streamable-http"
}
}
}
}
Any MCP client · MCP Inspector
Point any Streamable-HTTP client at the endpoint. To poke around interactively:
npx @modelcontextprotocol/inspector # Transport: "Streamable HTTP" → URL: https://worldclock.pro/mcp
What you can ask
You don't call these tools yourself: your assistant picks the right one. Once connected, just ask:
get_current_time
Current time in one or many places at once (up to 50).
“What time is it in Tokyo, Paris, and UTC right now?”
convert_time
Move one moment across time zones.
“If it's 9 AM Monday in New York, what time is it in Sydney?”
time_by_coordinates
Local time at any latitude/longitude on Earth.
“What's the local time at 48.85, 2.35?”
get_dst_transitions
Whether a place observes daylight saving, and when the clocks change.
“When do the clocks change in London this year?”
search_cities
Look up cities by name: any language, accents optional.
“Find cities called “San Jose”.”
Ways to describe a place
What agents do with it
Plan meetings and calls across zones
"When is a good time to call Singapore from New York?" Your assistant checks candidate slots with convert_time, with daylight saving handled on the actual date, not today's offset.
Keep cron jobs honest
Turn "6 AM Berlin time, year round" into the right UTC schedule, and know in advance when a clock change would break it.
Brief travellers
Land at 3:40 PM in Tokyo and instantly know what time that is back home, or what the timezone is at any coordinates en route.
Normalize log timestamps
Convert UTC incident timestamps into the local time of every affected region in one call.
This endpoint speaks JSON-RPC 2.0 over Streamable HTTP on POST https://worldclock.pro/mcp; this page is what a browser sees at the same address. It's public and read-only: the tools return computed time facts over public GeoNames-derived data, so there's nothing to sign in for. Every response includes a source_url citing the matching page here. Machine-readable manifest: server card · skill and plugin repo: github.com/worldclockpro/worldclock-mcp.
