mcp_resource_template

The mcp_resource_template macro generates utility methods for parameterized resource templates.

#[macros::mcp_resource_template(
    uri_template = "users://{user_id}/profile",
    name = "User Profile",
    description = "Profile data for a specific user",
    mime_type = "application/json",
)]
#[derive(Debug, macros::JsonSchema)]
pub struct UserProfileTemplate;

Generated methods:

• UserProfileTemplate::resource_template() - creates a ResourceTemplate instance
• UserProfileTemplate::resource_template_uri() - returns the URI template

Using in Handler

async fn handle_list_resource_templates_request(
    &self, _params: Option<PaginatedRequestParams>, _runtime: Arc<dyn McpServer>,
) -> Result<ListResourceTemplatesResult, RpcError> {
    Ok(ListResourceTemplatesResult {
        resource_templates: vec![UserProfileTemplate::resource_template()],
        meta: None, next_cursor: None,
    })
}
