What your AI can do hereConnector snapshot 2026-08-23
Connect Cal to ChatGPT or Claude with your own Cal login or an API key, and your AI can run 175 of its actions. 80 of those only read and change nothing. 28 can delete or send something that cannot be undone, so those need a boundary you set before anyone runs them.
Cal also publishes its own MCP server, which is a second way in. Vendor documentation
This describes what Cal supports, which is one half of the picture. Where you
start depends on the task and on how much you have handed over before, and no page can
tell you that from a count.
