What it does

chrono-mcp is an MCP server for timezone conversion, date/time arithmetic, and recurrence expansion. It supports batch operations on up to 100,000 timestamps, RFC 9557 IXDTF and RFC 5545 RRULE formats, and appends a temporal context envelope to every response so agents can track elapsed time between calls.

  • Convert a datetime to multiple timezones simultaneously with locale-aware formatting and UTC offset output.
  • Expand an RFC 5545 RRULE or ISO 8601 repeating interval into concrete occurrences, DST-correct, within a specified window.
  • Run statistical analysis (earliest, latest, mean interval, standard deviation) over a batch of up to 100,000 timestamps in a single call.

Tools this server exposes

ToolDoes
get_timeReturns the current time or converts a given datetime across one or more IANA timezones in various output formats.
time_calculatorPerforms date/time arithmetic (add, subtract, diff, duration_between, sort, stats, expand) on single values or batches up to 100,000 timestamps.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
