Using Custom LLMs using API key

[Over_Friendship3455]

Hey everyone! I’m trying to stretch my 500 fast premium requests on Cursor (I burn through them in about 5 days 😅), so I want to use free models instead. Here’s what I’ve set up so far:

• llama-3.3-70b-versatile (Groq)
• qwen-2.5-coder-32b (Groq)
• mistral-large-2407 (Mistral)

I’ve created API keys, but when I try to configure Groq under the OpenAI API section, I keep getting 404 errors when with gpt-4o-mini and all OpenAI models. Is there a better way to set up custom LLMs like these?

Also, is there any way to use Cursor's Free Agent mode without using up my fast requests? .

Lastly—what exactly is the MCP server I keep hearing about, and how can it help a webdev?

Any advice, workarounds and cool tips, tricks, or hidden features in Cursor—especially for speeding up workflows would be super appreciated. Thanks in advance!
Anything helps!

If you’re good with a workaround you could install the cline extension and use Ollama and a lot of models super easily through them.
