Is it possible to use tools for ai agent on free plan?

Hey

I’m getting errors when trying to use a simple send email tool with an AI agent.
Is it possible to use tools on the free plan? (since custom variables aren’t available on the free plan)

*I used the module tool, so it creates the variables on its own, and everything looks fine, but I get this error: “An unexpected error occurred while executing the agent. | It looks like something went wrong. Please give us time to fix it.“

*Update: the issue was resolved by using a better model (previously used Make’s medium model and than switched to high)
