MCP & Tool Protocols
Resource URI
An identifier used to locate a resource exposed by a connected system.
Example
A resource URI uniquely identifies the handbook page exposed by an MCP server.
Why it matters
It gives applications a consistent way to refer to a particular piece of content.
You'll hear it
“That identifier points to a different resource than the one we wanted.”
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
- Is a resource URI always an ordinary website link?
- No. A connected system can use other identifier formats.
- Does knowing the URI grant permission to read it?
- No. Access checks can still apply.
- Can a resource's contents change while its identifier stays the same?
- Yes. A stable identifier may point to material that is updated over time.
