Tool Policies Framework

AI agent governance for every tool call.

AI agent governance and access control for every tool call. Define policies once, enforce them on every agent action, and produce attribution for every decision.

What goes wrong without AI agent governance.

Agents wired directly to tools fail in predictable ways. Each one is a regulator-visible incident waiting for a transcript.

Unbounded tool access

Agents call any registered tool with no upstream check on whether the action fits the customer, session, or risk.

Inconsistent enforcement

Two agents see the same risky request and make different choices. No single source of truth your auditors can point to.

Rules buried in prompts

Policy lives in system prompts and ad-hoc code. It drifts, disappears in PR reviews, and cannot be reproduced under audit.

Permissions out of step

Sensitive tools fire for sessions that never met the identity bar. The agent does not know the difference. The regulator will.

One versioned policy, enforced on every agent.

Centralized AI agent policy

Policy lives in one place, not in every prompt.

Define AI agent governance once, in versioned policy, instead of scattering rules across system prompts and tool wrappers. Reviewed, tested, and rolled out like any other code, with the same enforcement on every agent.

Real-time policy enforcement

Allow, escalate, or block, before the tool runs.

AI policy enforcement happens on the execution path. Low-risk actions pass, sensitive ones escalate for approval, and anything out of bounds is blocked before it fires. Same request, same decision, regardless of agent.

Signed audit record

AI agent access control

Every decision tied to an agent, a policy, and a reason.

AI agent access control with full attribution: each allow or block is recorded with the agent, session context, policy that applied, and reason. When a regulator asks why an action was permitted, the answer is already attributed, not reconstructed.

Built for the execution path.

Policy enforcement has to be fast, consistent, and complete. Every tool call gets the same governed decision before anything executes.

100%

Tool calls evaluated

Every planned action is checked against policy before the tool runs.

<200ms

Added latency

Inline enforcement on the execution path, without routing work to an after-the-fact review queue.

100%

Action coverage

Policies apply across prompts, tool calls, tool results, and outputs, with no sampling gaps.

Versioned source of truth

Rules live in one reviewable policy surface instead of being scattered across prompts and wrappers.

What security teams are saying.

Before we started using Averta, we were hesitant to share sensitive information with agents. Averta changed that by providing the security and trust we needed, allowing us to significantly enhance our customer service experience.

Policy enforcement, specifics.

What teams ask when they evaluate the policy framework against their existing controls.

AI agent governance is the policy layer that decides what an AI agent is allowed to do at runtime, on every tool call. Instead of trusting prompts to encode the rules, governance moves them into a versioned policy that the system enforces inline, allow, escalate, or block, with attribution for every decision.

In the Averta dashboard or through the API, not in agent prompts. A policy is a set of rules you attach to an agent's API key.

On the execution path, before any tool call runs, at the request, tool, tool-result, and output stages.

The intent and risk score of a request, which tools an agent may use, the contents of a tool result, and the model's output. A policy can allow, escalate, or block, restrict which tools are exposed, or rewrite an unsafe output.

A blocked call never executes, an escalated call is held for review, and the decision is recorded with full context. You can also restrict an agent to a safe subset of tools rather than blocking outright.

Each agent runs the policy you attach to it, so the same request gets the same decision every time, regardless of which agent or framework makes it.

Yes. The policy layer sits at the tool-execution boundary, independent of model and framework. Switching models or upgrading agents does not change the policy surface.

Classification scores intent and risk, the MCP Gateway exposes approved tools, and the Tool Policies Framework decides allow, escalate, or block on every call. Together they govern the full path from input to action.
