Give an AI agent its own identity and only the permissions needed for its specific task. Scope those permissions to the narrowest available resources and actions, enforce limits in the connected apps and tools—not just in the prompt—and keep credentials, sessions, and network access contained. Add human review for high-impact actions, then log access and test how to revoke it.
Start by defining what the agent must do
Before connecting an app, write down the task in terms of the data the agent needs and the actions it must take. For each connection, specify the resource (such as one mailbox, a workspace, or a collection) and whether the agent needs to read, write, delete, or administer it. This makes it possible to grant only the required capabilities instead of giving the agent a broad account and hoping its instructions keep it within bounds. OWASP recommends restricting tools and permissions to the minimum needed for the task: AI Agent Security Cheat Sheet.

- Use read-only access when the task only requires retrieval or analysis.
- Keep read and write capabilities separate where the platform allows it; do not grant deletion or administration merely because a connector offers them.
- Limit access to a specific workspace, team, mailbox, collection, or other resource rather than an entire organization.
- Do not enable unreviewed integrations or cross-tenant access by default.
Instructions such as “do not delete files” may help guide behavior, but they are not an enforceable permission boundary. A prompt injection, tool-chain error, or unsafe response can still lead to an unintended action. Enforce authorization in the app or service that owns the data, and have each downstream service check access when a request arrives. See Google Cloud’s AI security and safety guidance and the OWASP guidance.
Choose whether the agent acts for a user or on its own
The right identity model depends on whether a person is signed in and present when the agent works. Microsoft documents two patterns for Microsoft Entra agents; other platforms may use different names, scopes, and controls.
#1 Best Overall
- Compatible Model(s): Magicmoon brand filter only for 24 inch -diagonally measured - widescreen monitor - aspect ratio 16:9 - filter size: width: 20 15/16", Height: 11 13/16" (531mm x 298mm)
- Superior Privacy: The computer privacy filter makes the screen appear dark when looking at it from an angle (the angle is about 30 to 60 degree), but bright when looking directly at it. To change the privacy level - simply adjust your monitor’s brightness accordingly
- Eye and Screen Protection: Privacy Filter does not only protect your private life but also protects your eyes by blocking 30% of blue light , blocking the harmful blue light between 380 to 495 nm, it filters out the blue light and relieves eye strain
- Perfect For Open Workspaces: Great for maintaining screen privacy in open work spaces
- Includes Two Options: Option 1 uses clear adhesive strips that securely attach to any computer screen. Option 2 (for computer screens with a raised bezel only) uses slide mount tabs that easily stick to the display frame, allowing you to slide the privacy screen filter on and off as needed
| Permission model | When it fits | What it means |
|---|---|---|
| Delegated permissions | An interactive agent acts for a signed-in user. | The agent’s access is delegated from that user. The grant should still be scoped to the needed resources and actions. |
| Application permissions | An autonomous agent runs without a user present. | The application identity receives permission to act without an interactive user session. Keep its scope particularly narrow and review the grant carefully. |
These distinctions and Microsoft-specific grant mechanisms are described in Microsoft’s guidance on granting agents access to Microsoft 365 resources. Its examples include access packages for standardized grants, narrow-scope Azure RBAC, per-mailbox Exchange RBAC, and per-team Teams resource-specific consent. They are examples for Microsoft services, not guarantees that equivalent controls exist elsewhere.
Put credentials outside the agent’s reach where possible
A long-lived key or token exposed to the agent’s runtime can be read by code running there, including agent-generated code. Avoid placing application or third-party credentials in prompts, generated code, transcripts, or logs. Where possible, have a trusted application, proxy, or secrets service add a scoped credential only when a request is sent to an approved destination, and return only the result the tool needs. This reduces direct exposure but does not make a credential safe if it is injected into a runtime the agent can inspect. OpenAI discusses credential handling and related sandbox boundaries in its Sandbox security guidance.

If you suspect a credential has been exposed, revoke or rotate it and invalidate related tokens as the platform permits; do not rely on removing it from a prompt or log alone.
Constrain tools, sessions, and network access
Limit both what the agent can call and what each call can affect. A tool that can search one approved collection is safer than a general-purpose tool with access to every connected account. Match the tool’s available operations and resource scope to the task, and ensure the destination service checks authorization for each request.

- Use isolated compute for workloads that should not share data.
- Separate sessions and memory by user or tenant so one person’s context is not exposed to another.
- Restrict outbound network traffic to approved endpoints rather than allowing arbitrary destinations.
- Review combinations of tools as well as individual permissions: innocuous capabilities can become dangerous when chained together.
These controls address risks including prompt injection, tool abuse, data exfiltration, memory poisoning, credential exposure, privilege escalation through combined tools, and cascading failures. Isolation can reduce the blast radius, but it does not replace authorization at the connected service. See AWS guidance on secure access and implementation of generative AI agents, Google Cloud’s guidance, and the OWASP checklist.
Require human review for actions with real consequences
Use explicit approval or independent review before sensitive, irreversible, administrative, financial, or externally visible operations. Examples include deleting records, changing access, sending a message outside the organization, or making a payment. Keep the agent’s underlying permissions narrow even when an approval step is present.

Approval is a useful control, not a guarantee: an approver can accept a malicious or destructive suggestion without checking it carefully. Google Cloud discusses this limitation in its AI security and safety guidance. Make the approval screen show the target resource and proposed action clearly enough for a reviewer to judge what will happen.

Log access, review grants, and rehearse revocation
For each action, record the agent identity, effective role and scope, resource, action, correlation identifier, and acting user when applicable. Review the combined permissions the agent receives across its tools and connected services, not just the settings in one app. Microsoft’s least-privilege guidance for AI agents treats explicit, reviewable authority as a core part of agent security.

Test the removal procedure before relying on it. Confirm who can disable the identity, rotate credentials, invalidate tokens, and remove stale grants, and verify that those actions actually stop access. Repeat the review when the agent’s tools, workflow, data, or operating environment changes materially.
As Microsoft Learn puts the underlying question: “As organizations adopt agentic AI, the security question shifts from whether an agent can complete a task to whether it should be allowed to perform each action, against which resources, and under whose authority.”
