Wraps the 3DiVi Face SDK Processing Block API as MCP tools so Claude can detect faces, run liveness checks, verify identity, and search galleries without you writing SDK integration code. All nine tools (detect_faces, check_liveness, extract_template, verify_face, search_face, estimate_attributes, estimate_emotion, assess_quality, detect_mask) run on your machine with no cloud dependency. Built for regulated environments where GDPR or BIPA prohibit sending biometric data to third parties. Requires a 3DiVi Face SDK 3.29 license and runs over stdio. The only local biometric MCP option if Azure cloud is off the table for compliance reasons.
