CtrlAI

About CtrlAI

CtrlAI is a transparent HTTP proxy that sits between autonomous AI agents and LLM providers to enforce guardrails, audit actions, and block unsafe tool calls without requiring SDK changes. It is open-source (MIT) and can be self-hosted or run with an enterprise-managed deployment.

Review

CtrlAI focuses on preventing dangerous or unintended agent behavior by intercepting every model response and evaluating tool calls against configurable rules. It aims to keep agents operational while preventing risky actions and providing a clear, tamper-evident audit trail for investigation and compliance.

Key Features

• Transparent HTTP proxy that works with agents by changing their baseUrl-no SDK modification required.
• Evaluates and enforces configurable guardrail rules (blocks SSH/credential exfiltration, destructive commands, camera/location access, unsolicited messaging, etc.).
• Rewrites or annotates responses so the agent continues gracefully (uses stop_reason adjustments and clear block messages rather than raw errors).
• Tamper-evident, SHA-256 hash-chained audit trail with daily rotation and SQLite indexing for searchable logs and forensic review.
• Per-agent policies, multi-provider routing, emergency kill switch, and hot-reloadable configuration for quick updates.

Pricing and Value

CtrlAI is available as a free, open-source project under the MIT license for self-hosting and extension. For organizations that need centralized policy management, SSO, and managed deployments, an enterprise offering is available (contact enterprise@cirtusai.com for details). The tool's main value is reducing operational and security risk from autonomous agents while preserving agent behavior and providing clear auditability for incidents and compliance reviews.

Pros

• Zero-code integration for most agent SDKs-simple to add by changing baseUrl.
• Granular, configurable guardrails that cover many high-risk actions out of the box.
• Clear audit logs with cryptographic chaining make post-incident review straightforward.
• Per-agent identities and routing allow multiple agents and providers to run through one proxy with separate policies.
• Emergency kill switch and hot-reloadable rules help respond quickly to incidents.

Cons

• Strict rules can cause agents to retry or loop if prompts expect blocked capabilities; rules require tuning to match workflows.
• Initial provider support covers several major LLMs, but full parity with all providers may require additional updates.
• Self-hosting and ops for high-availability deployments require infrastructure and maintenance effort for production use.

CtrlAI is well suited for developer teams building and deploying autonomous agents who need security controls, clear auditability, and minimal SDK disruption. It is a practical choice for security-conscious organizations, startups shipping agent features, and anyone who prefers an open-source self-hostable option with an enterprise upgrade path.
