What your AI can do

Tasks and schedule

List tasks for any date range, filtered by project or resource, and create, update or delete tasks with dates, resources and utilization.

Resources and projects

List, read, create and update resources and projects, including archived ones, with status, color and custom data fields.

Log time spent on a task with date and description, and look up the users in your Ganttic account.

It finds the task and logs 90 minutes of used time with today's date.

Questions

What can the AI do in Ganttic?

The AI can list and read tasks, projects, resources, users and the custom data fields for projects and tasks. It can create and update tasks, projects and resources, log time on a task and delete a task if you switch that tool on.

Does the AI see my Ganttic credentials?

No. Your Ganttic API token 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 task is permanent, and it and other changes to the plan 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 Ganttic account.

Who can get the Ganttic API token?

An account administrator finds it in Ganttic under Settings > API. There is one token for the account, so generating a new one stops the old one right away. If you do that, paste the new token into PipMCP.
