UseHourly
The free, open-source time tracker your AI assistant can use. Connect Claude, ChatGPT, Cursor or any MCP assistant and say “log 3 hours on Acme, then make this week’s timesheet for sign-off”. Or log your day in seconds yourself: type 1.5, 1:30 or 90m, press Enter, done.
Live: https://usehourly.app · Free to use, no paywall, no ads.

What it does
- Quick entry. Pick a project, type the time the way you would say it, add a note. Or press Start and let the timer count.
- Weekly timesheet. Every project and every day in one editable grid. Fill several days at once, add more entries to a day, move an entry to another date.
- Month calendar with per-project totals.
- Invoices. Turn billable hours into a PDF invoice, track paid and unpaid, re-download any time.
- Year summary. Hours, earnings, invoiced and received by quarter and month, ready for your accountant.
- Export. Excel for any week, month or custom date range (for example March 3 to April 20), and one zip with everything: every client, all time.
- Try it first. “Try it with sample data” on the home page opens a throwaway account filled with a month of work. No sign-up; keep it with one click if you like it.
- Switching from Toggl or Clockify? Import their CSV export from the Account page. Clients and projects are created for you, and importing the same file twice adds nothing.
- AI first: works with your assistant (MCP). Any MCP client (Claude, Cursor, VS Code, ChatGPT, your own agent) can log time, start timers, build a client’s timesheet, create a private sign-off link and prepare invoices. See below.
- Free calculator. Hours calculator: add up times and get decimal hours, no account needed.
- Your data is yours. Per-user isolation; everything you log can be exported at any time.
Use it from any AI assistant (MCP server)
UseHourly runs a remote Model Context Protocol server at https://usehourly.app/api/mcp (Streamable HTTP). It has 32 tools for projects, clients, time entries, timers, timesheets, invoices and reports; each one runs as you, so it only sees your own data. Create a token on Account > AI assistants (read-only or read and write, with an expiry), then:
claude mcp add --transport http usehourly https://usehourly.app/api/mcp --header "Authorization: Bearer "
That example is for Claude Code. Other clients just need the URL and an Authorization: Bearer header in their MCP settings.
Cursor (~/.cursor/mcp.json):
