DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Enhanced Elicitation with Natural Language Date/Time Parsing

What

MCP elicitation now supports natural language date/time input with intelligent parsing.

Details
  • Accepts natural language: "tomorrow", "next Monday", "jan 1st 2025", "in 2 hours"
  • Converts to ISO 8601 format automatically
  • Prefers future dates over past dates when ambiguous
  • For dates without times, omits the time component
  • Supports multiple formats: uri, email, date, date-time
  • Shows current context (date, time, timezone, day of week) to help parsing
  • Includes minItems/maxItems validation for selection elicitations
  • Gracefully handles invalid input with clear error messages
Evidence

Date parser prompt (search for "You are a date/time parser")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
