CtrlAI: Transparent Proxy for Securing AI Agents

Imagine your AI agent wakes up at 3 AM and sends your CEO a message: “You’re a terrible leader.” That’s the reality of autonomous AI systems—unpredictable, powerful, and sometimes dangerous. Enter CtrlAI, a transparent HTTP proxy designed to secure AI agents by enforcing guardrails, auditing behavior, and blocking unsafe tool calls without requiring code changes.

How CtrlAI Works

CtrlAI sits between your AI agent and the LLM provider, acting as a security layer. It intercepts every tool call the model attempts and evaluates it against configurable rules. If a call violates security policies—like accessing SSH keys or sending unsolicited messages—CtrlAI blocks it and rewrites the response so the agent continues operating smoothly.

Key Features

• Intercept LLM Responses: Works with Anthropic, OpenAI, and other providers to block dangerous actions.
• Configurable Guardrails: Customize rules to block SSH key access, credential exfiltration, or destructive commands.
• Tamper-Proof Audit Trail: Logs all actions with SHA-256 hash chaining for secure tracking.
• Emergency Kill Switch: Terminate any agent mid-session instantly.

Why CtrlAI Stands Out

Unlike traditional security tools, CtrlAI doesn’t disrupt your workflow. It requires zero SDK modifications and works with any framework supporting custom base URLs. For example, you can route multiple agents through a single proxy, each with its own policies and audit logs. This means you can isolate risks—kill one agent without affecting others.

Real-World Use Case

Consider an agent tasked with deploying code. Without CtrlAI, it might accidentally execute a destructive command like rm -rf /. CtrlAI blocks this action, logs it, and lets the agent proceed as if the command never existed. The agent doesn’t crash; it simply moves on, preserving system stability.

Getting Started in 60 Seconds

1. Install CtrlAI via ctrlai start.
2. Point your agent’s baseUrl to CtrlAI’s proxy.
3. Access the dashboard at /dashboard to monitor activity.
4. Use the CLI to manage rules, audit logs, or trigger the kill switch.

Open Source and Enterprise Options

CtrlAI is open-source under MIT, allowing developers to self-host and extend its functionality. For teams needing centralized policies or SSO, enterprise features are available via [email protected].

Conclusion

CtrlAI redefines AI security by combining transparency, flexibility, and zero-code integration. Whether you’re deploying a single agent or managing a fleet, it ensures your systems stay safe without sacrificing autonomy. Try CtrlAI today and see how it secures your AI workflows.

FAQs

What is CtrlAI and how does it secure AI agents?

CtrlAI is a transparent proxy that enforces guardrails and blocks unsafe tool calls. It works by intercepting LLM responses and rewriting them to prevent harmful actions.

Can CtrlAI work with multiple LLM providers?

Yes, it supports Anthropic, OpenAI, and others, with plans to expand. Each agent can use a different provider under the same proxy.

How does CtrlAI handle audit trails?

It logs all actions in a tamper-proof SHA-256 hash-chained audit trail, with daily rotation and SQLite indexing for easy tracking.

Is CtrlAI open source?

Yes, it’s MIT-licensed. Developers can self-host, modify, or extend the code freely.

What happens if an agent tries to access a blocked tool?

CtrlAI injects a clear message like “[CtrlAI] Blocked: Cannot access SSH private keys” and modifies the response to keep the agent operational.
