Builds a text MCP content block. The block passes through the automatic result coercion untouched, so use it when a tool wants exact control over what the client renders. Returns a struct with type = "text" and the given text.
mcpText( text )
→ returns struct
A tool can return an explicit content block instead of relying on automatic coercion.
function chart() tool="chart" {
return mcpText( "Here is the chart:" );
}Expected Result: { type: "text", text: "Here is the chart:" }
