Struct ToolMeta 

pub struct ToolMeta {
    pub ui_resource_uri: Option<String>,
}

Tool metadata for protocol extensions

This supports the MCP Apps Extension (SEP-1865) and future extensions that need to attach metadata to tools.

Fields

ui_resource_uri: Option<String>

Reference to a UI resource (MCP Apps Extension)

Links this tool to an interactive HTML interface that can be displayed when the tool is called. The URI should use the ui:// scheme and reference a resource returned by list_resources.

Example: "ui://charts/bar-chart"
