The Problem

Agent Autonomy Expands the Blast Radius

When agents invoke tools across systems, a single run can trigger irreversible actions before any human notices.

Over-Permissioned Tools

Agents inherit broad access, so “helpful” tool use is hard to distinguish from unsafe actions.

High-Risk Actions Happen Fast

Deletes, exports, payments, and external POSTs can execute in seconds, before review is possible.

Tool Calls Carry Sensitive Data

Tool inputs and outputs can route sensitive data through connectors, RAG, and MCP servers.

Hard to Reconstruct What Happened

Agent workflows span multiple tools and steps, making incident review slow and uncertain.

Decision Flow

A Policy Gate for Tool Calls

Tool calls are checked against allowed tools and scope, then recorded for audit and investigation.

Decision moment: an agent attempts a tool action, so ThirdLaw allows, denies, or requires approval based on policy
The Solution

Enforce Policy on Every Tool Call

Evaluate every tool call in context, then allow, block, or route for approval with a complete action trail.

Scoped Tool Access

Allow or deny tools by role, environment, app, and agent so broad credentials don’t become broad autonomy.

Parameter Constraints

Constrain risky parameters like destinations, objects, amounts, and query scope so tool calls stay within policy.

Approval Checkpoints

Require human review for exports, deletions, payments, or external POSTs when policy demands a pause.

Action Trail for Investigations

Capture the steps, tool calls, and decisions so teams can quickly reconstruct what happened and why it was allowed.

Use Cases

Put Guardrails on Agent Actions

Practical controls for the moments that turn agent behavior into operational risk.

Tool Permissions

Restrict tools by role and environment so production agents can’t access dev-only or high-risk connectors.

Action Approvals

Require review for exports, deletions, payments, or external sharing before execution.

MCP Server Governance

Constrain what tool servers can receive and return so sensitive fields don’t flow out through tool calls.

Agent Chains

Keep multi-step agent workflows within limits by enforcing consistent tool and action policy across the chain.

How We're Different

Tool Calls are Where Agent Risk Becomes Real

Most agent failures look “authorized” in isolation. ThirdLaw governs tool execution so risk is controlled at the moment of impact.

Scoped Permissions by Context

Allow the same tool in one route or role and require approval in another.

High-Risk Action Gating

Configure allow, block, reroute, or approval requirements for irreversible actions.

A Record of Every Decision

Keep allow, block, and approval decisions on the tool call so investigations don’t require log correlation.
