Building a product, but how to call MCP when using LLMs?

Hello world,

I'm a backend software engineer in tech and we use Augment/Cursor/Windsurf for development. We add MCP servers to these tools.

I'm now doing a personal project. However, I'm trying to understand what i need to do to build a system where my LLM can interact with MCP servers when not using these tools? The gap is regarding how/when i should call MCP during the conversation(/if at all). Or will the LLM figure that out automatically. Planning to start with standard models like the ones from OpenAi/Google, Gemini, Or Anthropic.

Can you share some pointers? Additionally, any detailed blog posts/videos will be great help.

Happy building!
