Enables natural language time tracking and reporting for Harvest, including automatic leave requests, project/task matching, and date parsing.

An MCP server that lets you log Harvest time entries using natural language, including special handling for leave requests. This server makes time tracking more intuitive by understanding natural language inputs and automatically handling common scenarios like leave requests.

  • ? Timezone support
  • ? Automatic project and task matching
  • ? Smart date parsing (today, yesterday, etc.)

Prerequisites

  • Node.js installed
