Resource template

Also written: resource templates, URI template, URI templates

A pattern like docs://help/{id} that describes a whole family of MCP resources without listing each one.

Nobody prints a list of every apartment in a city. "Apartment {number}, 12 Main Street" covers them all. Listing every invoice or every customer record isn't practical either. A resource template describes a whole family with an RFC 6570 URI template, such as docs://help/{id} or crm://customers/{customer_id}/orders. resources/templates/list returns them. A client fills in the variables to build a URI, then reads it.
