Questions

What can the AI do in COR?

It can search and read projects, tasks, clients, contacts, users, teams, comments and logged hours. It can create and update clients, projects and tasks, assign users to tasks, add project collaborators, post comments and delete tasks.

Does the AI see my COR credentials?

No. Your COR API key and client secret are encrypted at rest and never shown to the AI. After you save them, they are 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 with lookups only. Deleting a task is permanent, and comments may notify project or task members, so these tools 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 HeyMyApps 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?

COR connects with OAuth, and OAuth connections need the HeyMyApps Pro plan or above. HeyMyApps also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own COR account.

Which task statuses does COR use?

COR tasks have four statuses: nueva (new), en_proceso (in progress), estancada (stalled) and finalizada (finished). You can ask in plain words, and the AI sets the matching status when it updates a task.
