Agent terminated due to error 2

What is going on here? I’ve tried every model. Closed Antigravity and opened again. Same error all the time. I can’t believe we have to pay for this. I need it for business. Absolutely unacceptable for a multi-billion dollar company. Hey Google! Imagine you pay someone for a service, and it constantly breaks. How would you respond?

I’ve identified the problem. My earlier rant was unwarranted.

The issue stems from MCPs. There was 1 MCP server cause malformed agent tool calls. If anyone else runs into the same issue, deactivate MCPs one by one till you find the culprit.

Google Team…sorry for my verbal abuse.
