Nothing serious here today

Today is the operative word: we check Meridian every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

meridian_convert_time

Use when you need to convert a specific wall-clock time from one place to others, for any date. It uses the real tz database, so daylight saving is right for that exact date (the US and Europe switch on different weeks), and it warns when the time does not exist (spring forward) or happens twice (fall back). Time accepts "15:00", "3:30pm", "noon", "now" or an ISO local time like 2026-11-05T15:00 (no Z). Date defaults to today in the source zone. Returns {input, utc, source:{...}, converted:[{place, zone, local, time_12h, date, utc_offset, abbreviation, day_note, hours_ahead_of_source}], warning?, summary, open_url}.

meridian_meeting_slots

Use when you need to schedule a call across several places. Scans the day in 15-minute steps and ranks start times so the most people are inside working hours and nobody is at night, using each place's real offset and DST for that date. Returns up to 5 slots with each person's local start and end, and says plainly when no time works for everyone. Defaults: working hours 9 to 17, 60 minutes, date today in the first place.

meridian_now

Use when you need to know what time or date it is right now somewhere. You have no clock of your own, so never guess the current time. Returns the real current time, date, UTC offset, abbreviation and daylight saving status for each place. Places can be cities ("Tokyo"), IANA zones ("Europe/Paris"), abbreviations ("PST") or "UTC+5:30".

meridian_zone_info

Use when you need to answer "what is the UTC offset of X", "does X observe daylight saving" and "when do the clocks change". Returns the current offset and abbreviation, whether the place observes DST, every clock change in the year with exact local before and after times, and the next change. Abbreviations like IST or CST are ambiguous, so the answer says which zone was used.

Meridian — questions

Answers built from our own checks of this server.

What can Meridian do?

It exposes 4 tools, read directly from the server on our last check. Among them: meridian_convert_time, meridian_meeting_slots, meridian_now, meridian_zone_info. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Meridian working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 17 of 17 checks got a reply (100.0%), average response time 86 ms. The bar chart above shows every period we have measured.

How do I connect Meridian?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Meridian need an API key?

No. Meridian completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Meridian?

It answers our handshake in 86 ms on average, which is faster than 93% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
