Harvest

Harvest MCP Server provides integration with the Harvest time tracking and project management API, allowing Claude and other AI assistants to interact with your Harvest account. Built by Taiste Oy, this server enables users to manage time entries, projects, clients, and tasks directly through conversation. The implementation uses FastMCP to expose a comprehensive set of tools for listing users, creating and managing time entries, starting/stopping timers, and retrieving detailed information about projects and clients. It authenticates with the Harvest API using environment variables and is designed to work seamlessly with Claude Desktop, making it particularly valuable for professionals who need to track time and manage projects without switching contexts.
