Hold

HOLD is an AI security platform that protects autonomous coding agents from prompt injection, unauthorized access, and unsafe actions. Using task-specific Intent Receipts, HOLD defines exactly what agents can read, modify, and access, enforcing permissions through a deterministic MCP gateway before execution. We integrate Guild.ai for agent workflow management, Semgrep for detecting risky code changes, and ClickHouse for real-time security monitoring and audit trails. To make security more accessible, we built a Codex-themed AI pet powered by OpenAI GPT that lives across the product interface. It proactively assists users as they navigate, remembers the full session context, answers questions, and explains what agents completed, what was blocked, and why. HOLD combines security, transparency, and intelligent assistance, allowing developers to build with autonomous AI agents while maintaining control and trust.
