What is the proper way to configure for FREE only with cursor?

[natesena]

I frequently get failed usage and answers like this in cursor:

The Solution
You need to add at least one API key to your .cursor/mcp.json file's env section. The easiest free options would be:
Google API key (Google offers free tier)
OpenRouter API key (has free models)
Set up local Ollama (completely free, no API key needed)

How do I make this completely compatible with cursor to NEVER use API keys?

You can't, cursor doesn't allow us access to their system so that we can prompt it ourselves unfortunately :(
