> h3. Context
> Part of an effort to reduce token consumption of the {{camel-jbang-mcp}} MCP server. The module exposes 31 tools, 6 resources, and 3 prompts; both tool schemas (loaded once per session) and tool results (per call) contribute to LLM context-window pressure for every user of the server.
> Related tickets in this effort are linked via "Relates to".
> Several records have nullable fields populated on some code paths and {{null}} on others. Example: {{OptionInfo.group}} is {{null}} for component options ({{CatalogTools.java:407}} passes {{null}}) but populated for endpoint options ({{CatalogTools.java:418}}). Without {{@JsonInclude(NON_NULL)}} or a customized {{ObjectMapper}}, every component option carries a useless {{"group": null}}.
> A grep across the module finds no {{JsonInclude}}, {{NON_NULL}}, or {{ObjectMapper}} references.
> h3. Proposed change
> Either:
> * Annotate the result records (and/or a common base) with {{@JsonInclude(JsonInclude.Include.NON_NULL)}}, OR
> * Configure the MCP Jackson {{ObjectMapper}} globally with {{setSerializationInclusion(Include.NON_NULL)}}.
> Same for nullable booleans where applicable.
> h3. Acceptance
> MCP responses no longer contain fields with {{null}} values.
