Question about MCP Resources vs Tools for CSV Graph Plotting

[Dhruv-mak]

Hi team,

I'm new to fast-agent and may be missing something obvious. I'm trying to understand the best approach for my use case:

I understand what MCP tools do, but I'm still confused about resources. I've noticed resources are typically used within tools, but I have a specific question:

If I have a function that plots graphs from CSV input, should I be using MCP resources? If yes, how would I configure an agent that has access to this resource and returns the generated image back to me?

Currently, I'm working with code similar to:

Any guidance on best practices for this scenario would be greatly appreciated!

Thank you.

Hi @Dhruv-mak -- hope you don't mind, but I'm going to transfer this to discussions.
