## TL;DR

MCP resources expose contextual data, prompts expose reusable interaction templates, and roots define the filesystem scope a client is willing to share with a server.

## Core Explanation

Tools are not the whole MCP surface. Resources let an agent discover and read contextual data without treating every lookup as an action. Prompts let a server publish reusable task templates that a client can display and fill with arguments. Roots give a server explicit boundaries for local files or workspaces that the client has made available.

For agent infrastructure, these three concepts help separate "what context exists", "what workflow template can be invoked", and "what local scope is authorized". That separation is useful for product UIs, security review, and reliable context assembly.
