MCP & Tool Protocols
MCP resource
Data or content an MCP server exposes for an AI application to read.
Example
An MCP resource gives the assistant read-only access to a project handbook.
Why it matters
It provides connected background material without requiring the AI to invent it.
You'll hear it
“The connection exposes the handbook as readable content.”
Can you control it?
Set by the team
The people building or running the AI choose this setup. An everyday user generally needs their help to change how this part works.
Common questions
- Does reading a resource mean it is accurate?
- No. The content may be outdated, incomplete or mistaken.
- Is a resource the same as an action tool?
- No. A resource supplies content; a tool may carry out an operation.
- Can access to a resource be restricted?
- Yes. The server and application can limit who is allowed to read it.
