## Description

This MCP server provides AI assistants with current datetime functionality through a simple proof-of-concept implementation built using the Roc programming language with JSON-RPC communication over stdin/stdout. The implementation offers a single tool for retrieving the current datetime in ISO 8601 format, featuring a complete MCP protocol handshake with initialization, tool discovery, and execution phases, along with colored stderr logging for debugging. Built as a demonstration of MCP server development in Roc with manual JSON formatting and basic error handling, it serves developers exploring functional programming approaches to MCP server implementation and teams needing a minimal datetime service that can be easily extended with additional time-related utilities.
