Literal URI template used to infer read variables and completion keys.
Optional_Extension metadata advertised on this template's
resources/templates/list descriptor. Use vendor-namespaced keys for
custom data.
This value is not copied into resources/read content entries; content
metadata must be returned by the callback on each entry's own _meta.
OptionalannotationsStandard MCP hints describing resources produced by this template.
OptionalcompleteOptional completion providers keyed by URI-template variable.
Static arrays use case-insensitive prefix matching. Dynamic callbacks may be synchronous or asynchronous and receive the current value plus the official completion context containing already-resolved arguments.
OptionaldescriptionHuman-readable description.
OptionalmimeMIME type of the content.
Template display name.
OptionaltitleHuman-readable title (falls back to name).
RFC 6570 URI template with variables, e.g. "db://users/{id}".
Declares a parameterized resource matched by URI template.
