Find meeting slots inside everyone's working hours. It converts times between IANA zones with DST read from the ICU data in your Node build, ranks meeting slots where every participant is inside their own working hours, computes the daily overlap and clock changes, and writes .ics files.
Put now, convert_time, overlap and dst_changes in autoApprove: they are pure calculation. Keep ics_create out, because on the free tier it spends one of three files a month, and keep contacts_set out because it writes.
| You say | Tool |
|---|---|
| Find an hour next week for me in Warsaw, my client in New York and my designer in London. | find_meeting_slots |
| When are Warsaw and New York both at work? | overlap |
| Write me the .ics for Thursday 3pm Warsaw, 45 minutes. | ics_create |
Warsaw and New York on 09:00 to 17:00 days share 2 hours on 2026-09-10 and 3 hours on 2026-03-16, because the United States moves to daylight time on 8 March and Europe on 29 March. The overlap is computed on a real date, so it says so.
The file is mcp.json, and the key inside it is mcpServers.
| Scope | Path |

}No full-app restart. The MCP settings actions include restarting an unresponsive server if its tools do not appear.
The npm publish of @theluckystrike/mcp-timezone is pending; until then use the .mcpb bundle or a clone and build from the latest release.
There is no hosted endpoint for this one yet. MCP Timezone Planner runs locally over stdio with the config above, which is also the only form in which it reads and writes files on your own disk. Three of the servers in this collection are served at https://mcp.zovo.one/mcp/<name> over MCP streamable HTTP: time-tracker, price-tracker and invoice.
Cline is the one client here with an unsafe transport default. `type` selects it, and omitting `type` falls back to the legacy sse transport, so a streamable HTTP endpoint needs it written in or you will debug a server that is fine. Local entries carry "disabled" and an "autoApprove" array.
Free: conversions, overlap, DST and business days unlimited; slots for 3 participants over 5 days, 5 contacts, 3 ics a month. Pro is $19 once, verified offline.
The CLI reads ~/.cline/mcp.json. For the extension, do not hunt for a path: MCP Servers icon, Configure tab, Configure MCP Servers. cline mcp opens a wizard, and cline config mcp --json is the non-interactive form.
Set the transport explicitly. Omitting type falls back to the legacy sse transport, so streamable HTTP needs "type": "streamableHttp" written in. It is the one default here that sends you debugging a server that works.
Approve the read-only ones and leave the writing ones behind a click: each entry carries an autoApprove array and a disabled flag.
