Overview

AI-generated overview

Remote MCP server that plans meetings across time zones, expanding a time into each participant's local time or finding shared working-hour windows.

What you can do
  • Plan a one-off or recurring meeting once its time is known, expanding it into concrete dates shown in every participant's local time.
  • Find meeting windows when no time is set yet, listing the days when all participants fall within working hours and suggesting a start time.
  • Check working hours, weekends, public holidays and daylight-saving changes for each participant.
  • Return an "Open in Perfect Clock" link with each result.
When to use it
Useful when scheduling calls, syncs or recurring events with people or places in different time zones, and you want local times, holidays and DST handled rather than computed by hand.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or environment variable is declared.
Before you install
It returns links to the Perfect Clock site that the assistant is told to pass on as-is; treat those links as third-party content. Participant time zones and meeting details are sent to the remote service.

Installation

In SourceWeft

  1. Open Perfect Clock in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/cc.perfectclock%2Fperfect-clock/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

plan_meeting_schedule

Plan a meeting schedule

Plans a one-off or recurring meeting with people in other time zones when its time is known (e.g. "every other Tuesday at 10:00 Berlin time with Anna in Tbilisi"). Expands it into concrete dates and shows each one in every participant's local time, with working-hours checks, public holidays and daylight-saving shifts. Saves the schedule for 30 days and returns a private perfectclock.cc/s/... link that opens it in Perfect Clock.

find_meeting_windows

Find meeting windows

Finds when people in other time zones can meet, when the time is not decided yet: the windows on each day when all participants are within their working hours, accounting for weekends, public holidays and daylight-saving changes, and one suggested start time that fits the most days. Saves that suggested time on those days for 30 days and returns a private perfectclock.cc/s/... link that opens it in Perfect Clock.
