Full Harvest control in Claude Desktop

You can pull your latest hours and client details straight into your chat session. By calling `list_time_entries` and `get_client`, your agent fetches real-time data without you needing to tab-switch. This setup lets you draft invoices or update records on the fly. Simply ask your agent to use `create_invoice` or `update_client` to handle those admin tasks while you stay in your flow.

Automated time tracking for Claude Desktop

Stop jumping between your browser and your workspace to log your hours. Your agent uses `list_projects` to see what is active and then logs entries based on your current project status. Keeping your logs accurate becomes a background task. The server handles the connection so your agent can focus on organizing your billable data.

Direct client management for Claude Desktop

Onboard new clients or check existing account status without leaving the interface. Using `list_clients` and `get_my_profile`, your agent maintains a clear view of your business relationships. When you need to clean up your database, the `delete_client` tool gives you direct control. It keeps your Harvest environment tidy and relevant to your ongoing work.
