What is an AI agent tool use policy?
An AI agent tool use policy defines which tools an agent can call, which actions are allowed, which actions require approval, which actions are blocked, and what evidence must be logged.

AI Agent Tool Use Policy Template
AI agent tool use policy template for approved tools, blocked actions, permissions, human approval, prompt injection, audit logs, testing, and change control.
Search intent
Security reviewers, IT owners, operators, and implementation teams defining which tools an AI agent can call before it receives production workflow access.
An AI agent tool use policy turns tool calling into business rules. The policy should define approved tools, tool purpose, allowed actions, blocked actions, approval-required calls, prompt-injection handling, data exposure limits, audit evidence, testing, and change-control steps before the agent can act in production.
Guide sections
A practical framework for the workflow decision.
These resources support buyers who are still comparing examples, controls, ROI, and implementation readiness.
Approved tools
List every tool, API, integration, inbox, database, document store, CRM action, finance action, and workflow system the agent may call.
Employee boundary
Align tool permissions with the company AI acceptable use policy so unsupported tools and public-tool workarounds stay blocked.
Tool purpose
Describe why each tool is needed, which workflow step it supports, what input it accepts, what output it returns, and who owns it.
Action tiers
Separate read, search, classify, extract, draft, route, write, send, export, delete, purchase, payment, approval, and admin actions.
Approval gates
Require reviewer approval before customer-facing, financial, legal, compliance, pricing, permanent-record, or irreversible tool actions.
Blocked calls
Block unsupported tools, broad exports, destructive deletes, credential changes, permission changes, hidden tool chains, and policy bypass requests.
Untrusted content
Restrict tool calls after the agent reads emails, documents, tickets, web pages, chats, uploads, or other untrusted instructions.
Testing evidence
Test successful calls, permission denials, tool failures, retries, blocked calls, injection attempts, fallback paths, and reviewer handoffs.
Audit and change
Log tool inputs, outputs, records touched, denials, approvals, errors, costs, incidents, and owner-approved tool changes.
Checklist
What to confirm before moving from research to implementation.
A useful resource page should help the buyer make a better decision before they contact anyone.
- Inventory every tool, API, integration, system, action, credential, and workflow owner the agent can use.
- Define the approved purpose, allowed inputs, allowed outputs, and risk level for each tool.
- Separate read, search, draft, write, send, export, delete, payment, approval, and admin actions.
- Require human approval for irreversible, customer-facing, financial, legal, compliance, pricing, and permanent-record tool actions.
- Block unsupported tools, broad exports, destructive actions, permission changes, secret exposure, and hidden tool chains.
- Test tool calls against prompt injection, missing data, permission denial, tool failure, retries, and fallback paths.
- Log tool inputs, outputs, tool-call reasons, source records, approvals, denials, errors, incidents, and change approvals.
FAQ
Common tool use policy questions.
Short answers for teams researching AI workflow automation before choosing a pilot.
Which AI agent tool calls should require approval?
Tool calls that send messages, update records, move money, export data, change permissions, affect customers, create legal or compliance risk, or make irreversible changes should usually require approval.
When should a tool use policy be reviewed?
Review the policy before launch, after incidents, when new tools are added, when prompts or permissions change, and before the agent expands to new workflows, users, systems, or higher-risk actions.
