AI Agent Guardrails
Define what agents
can’t do.
Without explicit guardrails, agents will explore every edge case — including the ones you never wanted them to find. MUTX lets you write safety policies, enforce them at runtime, and see violations as first-class events instead of silent failures buried in a log file nobody reads.
Guardrail properties
Safety policies,
not safety theater.
Most guardrail implementations check a box without actually preventing anything. MUTX guardrails are enforced by the control plane at runtime — not by prompt instructions that the model can reason around when the stakes are high.
Runtime policy enforcement
Define what agents can call, what data they can access, and what operations are off-limits. MUTX evaluates these policies at runtime — not at write-time, not at review-time.
Safety boundaries
Put explicit walls around operations that should never happen — destructive tool calls, sensitive data access, operations without a human-in-the-loop gate. Boundaries that travel with the agent.
Violation visibility
When a guardrail is triggered, you see it. MUTX surfaces guardrail violations as first-class events — with the policy that was violated, the operation that was attempted, and the context that triggered it.
Policy versioning
Guardrail policies are versioned with the agent definition. You can audit what policy was active when a violation occurred, roll back to an earlier policy, and test policy changes against production traces.
Connected surfaces
Guardrails are
governance made concrete.
Auth boundaries and compliance requirements become concrete guardrail policies in MUTX. When a guardrail violation triggers, it surfaces through the monitoring surface, is recorded in the audit log, and can trigger a circuit breaker — all coordinated by the control plane.
Governance
Guardrails are where governance policies become runtime enforcement. The auth boundary that’s abstract in the governance model is the concrete guardrail that fires in production.
Monitoring
Guardrail violations are first-class monitoring events. You see the policy that was violated, the operation that was attempted, and the context — not just an error code.
Reliability
Guardrail violations can trigger circuit breakers. A repeated policy violation isn’t just a compliance problem — it’s a reliability signal that the control plane can act on.
Audit Logs
Every guardrail violation is logged with the policy version, the attempted operation, and the context. Records that satisfy compliance reviews, not just developer curiosity.
Get started
Write a policy and
watch it enforce.
Download the Mac app, write a guardrail policy for an agent, and trigger the violation deliberately. See what the violation event looks like in the control plane, what gets recorded in the audit log, and what the operator sees before users do.
