Method Details

mcpServerObjectMapper

@Bean(name="mcpServerObjectMapper",
      defaultCandidate=false)
public com.fasterxml.jackson.databind.ObjectMapper mcpServerObjectMapper()

Creates a configured ObjectMapper for MCP server JSON serialization.

This ObjectMapper is specifically configured for MCP protocol compliance with:

• Lenient deserialization that doesn't fail on unknown properties
• Proper handling of empty beans during serialization
• Exclusion of null values from JSON output
• Standard Jackson modules for Java 8, JSR-310, and Kotlin support

This bean can be overridden by providing a custom ObjectMapper bean with the name "mcpServerObjectMapper".

Returns:

configured ObjectMapper instance for MCP server operations
