@Bean(name="mcpServerJsonMapper",
      defaultCandidate=false)
public tools.jackson.databind.json.JsonMapper mcpServerJsonMapper()

Creates a configured JsonMapper for MCP server JSON serialization.

This JsonMapper 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
• Jackson modules via service loader

This bean can be overridden by providing a custom JsonMapper bean with the name "mcpServerJsonMapper".

Returns:

configured JsonMapper instance for MCP server operations
