# Resources and Prompts

> Understand when a problem should be modeled as a tool, a resource, or a prompt in Redop.

Tools are not the whole MCP surface.

## Use a tool when

* the client is asking the server to do work
* the result depends on action or business logic
* the caller expects an operation

## Use a resource when

* the client needs readable data
* the data has a stable URI
* subscriptions or change notifications make sense

## Use a prompt when

* the client needs reusable prompt material
* you want named arguments and prompt metadata
* the server should package prompt content, not execute work
