Questions

What can the AI do in Timesheet?

The AI can read projects, time entries, to-dos, expenses, notes, tags, rates, teams, time statistics, your profile, your absences and the timer's state. It can start, pause, resume and stop the timer, create and update time entries, projects and to-dos, record expenses and notes, and delete a time entry if you switch that tool on.

Does the AI see my Timesheet credentials?

No. Your Timesheet API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Deleting a time entry is permanent, and changing billed or paid flags affects what you invoice, so these actions can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Timesheet account.

Can the AI run the timer for me?

Yes. It can start the timer for a project, pause it for a break, resume it and stop it, and it can tell you whether the timer is running, paused or stopped and which project it is tracking.
