Function: toToolResult()

toToolResult(_entry, value, streamed, maxOutputBytes): object

Defined in: packages/mcp/src/invoke.ts:163

Convert an operation result into an MCP tool result.

Tools declare no outputSchema (serialized models rarely match their schema exactly), so structuredContent is informative only: the object itself, { value } for scalars and arrays, { items } for streamed chunks, and nothing for void.

Parameters

_entry

ToolEntry

the tool

value

unknown

operation result

streamed

boolean

whether value is the list of streamed chunks

maxOutputBytes

number

truncation threshold for the text content

Returns

object

the tool result
