temporal-mcp-server
An MCP server providing time, timezone, and duration tools including current time retrieval, timezone conversion, duration arithmetic with DST awareness, and elapsed time calculation. It supports local stdio/HTTP execution or a hosted Cloudflare Workers instance.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.
https://time.somamcp.com/mcpWhat you can do with it
- Get current time in any IANA timezone
- Convert ISO-8601 timestamps between timezones
- Add or subtract durations with calendar-aware arithmetic
- Calculate elapsed time between two timestamps

info
Returns identity and build information for this server (name, version, build commit, runtime, capability counts)
{
"type": "object"
}get_current_time
Return the current time as an epoch, a UTC ISO-8601 timestamp, and the wall-clock time in a given timezone.

"properties": {
"timezone": {
"type": "string",
"description": "IANA timezone identifier, e.g. 'America/New_York'. Defaults to UTC."
}
},
"additionalProperties": false
}convert_timezone
Render an ISO-8601 timestamp as wall-clock time in a target timezone.

},
"targetTimezone": {
"type": "string",
"description": "IANA timezone identifier to render in."
}
},
"additionalProperties": false
}add_duration
Add an ISO-8601 duration to a timestamp, in a timezone. Date units (Y/M/D) are calendar-aware: P1D across a DST boundary keeps the same wall-clock time the next day, and P1M on Jan 31 clamps to the end of February. Time units (H/M/S) are exact elapsed time, so PT24H really is 24 hours. Prefix the duration with '-' to subtract.

},
"timezone": {

},
"isoTimestamp": {
"type": "string",
"description": "ISO-8601 timestamp to shift."
}
},
"additionalProperties": false
}time_between
Exact elapsed time between two ISO-8601 timestamps, broken into days/hours/minutes/seconds plus a human-readable summary. All components share one sign, so they sum correctly; `direction` is 'past', 'future', or 'same'.
