UseHourly is a free, open-source timesheet for freelancers. Log your day in seconds, then turn the hours into a PDF invoice. Its remote MCP server gives any AI assistant 30 tools to log and edit time, run timers, manage clients and projects, create invoices and read annual reports. It uses Streamable HTTP with bearer tokens that can be read-only or read-write, set to expire, and are revoked on a password change.
