Developed Threat Intelligence Collections Management for the google/mcp-security repository, enabling users to create and manage collections with associated metadata and initial indicators of compromise. Focused on backend development using Python, the work included implementing API endpoints for creating collections, updating attributes, and managing IOCs, with privacy defaults set to private for enhanced security. Improved error handling was introduced to ensure reliable updates to IOCs, and dedicated commits provided clear traceability for auditing and rollback. The approach emphasized robust API integration and thorough testing, resulting in a maintainable and auditable system for managing threat intelligence data within the platform.
