What Are Resources?

Resources are the "read" half of MCP — data or documents an AI client can pull into context without calling an action. Unlike a Tool, a Resource never changes anything; it's purely for the AI to read.

There are two types: static resources hold fixed content you write once, and dynamic resources are backed by a live REST endpoint that Arthur calls at read time. Each resource declares a URI, an optional MIME type, and can be individually enabled or disabled.
