A Spring AI extension that adds privacy guardrails to LLM calls: PII tokenization before the model, per-tool original disclosure, Spring Security-based tool authorization, and pluggable content inspection. It packages these as Spring Boot starters with Maven Central publishing and extensive documentation, filling a real gap for Java teams deploying agentic applications.

Target audience: Java backend developers and enterprise teams building Spring AI LLM applications
