Class DefaultMcpToolResultConverter

java.lang.Object

dev.langchain4j.mcp.client.DefaultMcpToolResultConverter

All Implemented Interfaces:

McpToolResultConverter

public class DefaultMcpToolResultConverter
extends Object
implements McpToolResultConverter

Default converter for MCP tool responses backed by content[].

Supports text, images and embedded text resources. Images are returned as native ImageContent, preserving mixed-content order. Text-only results are joined with newlines so ToolExecutionResult.resultText() remains available. Binary resources and other unsupported content types fail explicitly; applications can provide a custom converter for them.
