io.github.MukundaKatta/timezone-mcp — Model Context Protocol (MCP) Server

This MCP server provides IANA timezone conversions using real DST rules. It produces real offsets via Node’s built-in Intl.DateTimeFormat, without requiring tzdata or any native binary. It uses the IANA database shipped with Node to compute timezone results for specific instants.

🛠️ Key Features

• IANA timezone conversions with real DST behavior
• Real offsets determined at the exact instant via Intl.DateTimeFormat
• No tzdata dependency and no native binary requirements

🚀 Use Cases

• Convert a UTC ISO instant to a local time in a target IANA timezone
• Get the current local time for a timezone
• Retrieve the UTC offset at a specific instant (DST-aware)

⚡ Developer Benefits

• Reduces timezone and DST hallucinations by using computed offsets and DST-aware rules
• Tools accept an instant (for exact-offset queries) and a timezone (IANA)

⚠️ Limitations

• Requires Node’s included IANA timezone data (no separate tzdata dependency)
