Important: Token Lifetime
The JWT expires after ~15 minutes. For ad-hoc Claude conversations this is fine — you mint a token and chat. For Claude scheduled workflows or long-running agents, automate a token refresh and update HRWORKS_TOKEN via the AnythingMCP admin API.
Date Interval Cap
hrworks_list_absences, _sick_leaves, _remote_work, _working_times cap at 1 year per call (or 31 days if interval=days). For multi-year analyses, ask Claude to iterate year by year.
