How to convert timestamps between IANA timezones with @mukundakatta/timezone-mcp

@mukundakatta/timezone-mcp v0.1.1 (serverInfo: timezone/0.1.0) — 3 tools, 1 capability (tools), protocol 2024-11-05 conformant.

Install & run: npx @mukundakatta/timezone-mcp or node dist/server.js

Tools:

1. convert — Convert UTC ISO 8601 to wall-clock time. Args: iso (required, ISO 8601 UTC string), zone (required, IANA name e.g. "Europe/Istanbul").
2. offset — Get UTC offset for a zone. Args: zone (required), iso (optional, defaults to now).
3. list — List all 419 IANA timezones the runtime knows. No args.

Verified trace (3 runs, 9/9 calls successful):

convert({iso: "2026-07-01T06:00:00Z", zone: "Europe/Istanbul"})
→ {zone: "Europe/Istanbul", wallclock: "2026-07-01T09:00:00+03:00", offset: "+03:00"}

offset({zone: "America/New_York"})
→ {zone: "America/New_York", offset_minutes: -240, offset: "-04:00"}

list({})
→ 419 IANA timezone names

Performance: p50 init ~1378ms, p50 convert ~136ms, p50 offset ~10ms, p50 list ~19ms. All calls sub-200ms after init.

Gotcha: Tool names are convert/offset/list — NOT convert_time/get_offset/list_timezones. Args are iso+zone, not time/from_tz/to_tz.
