Built-in Safety & Blast Radius Protection

Enterprise-grade safety layers ensure LLMs act within strict boundaries.

🔒 Edge PII Masking

When KLAROS_MCP_REDACT_PII=true is enabled, emails, phone numbers, and credit cards are automatically redacted on the client edge before reaching LLM provider servers.

🛡️ Consent & Service Window Gating

Outbound message tools hit the core Klaros engine. Messages land only if the 24-hour Meta service window is open or valid opt-in consent exists in the immutable audit ledger.
