AI Agent Permissions: What Should Your AI Agent Be Allowed to Do?

Your AI agent may read emails, prepare replies, and perform tasks. But who decides what it can actually do?

Watch: AI Agent Permissions in 27 Seconds

1. What Are AI Agent Permissions?

AI agent permissions are the rules and technical controls that determine which information an agent may access and which actions it may perform. An agent can be capable of an action without being authorized to execute it.

For example, an agent connected to your email might have permission to read selected messages and create draft replies, but not to send, delete, or forward them.

2. Three Types of Permissions

Permission	What it means	Example
Read	Access information	Read a selected email
Write	Create or modify content	Save a draft reply
Execute	Perform an external action	Send an email or make a booking

These are learning categories, not universal permission names. Actual application permissions vary.

3. Everyday Example: Your Email Assistant

Imagine telling your AI agent: “Help me reply to my meeting invitation.”

• The agent reads the relevant invitation.
• It proposes a suitable reply.
• You review the draft.
• The agent sends it only after authorization, if sending capability has been granted.

Key distinction: Asking an agent to prepare a reply does not automatically mean authorizing it to send one.

4. Why Permissions Matter

AI agents can misunderstand instructions, encounter malicious content, or take actions with unintended consequences. Broad permissions can increase the potential damage of an error.

The principle of least privilege means granting only the access necessary for the assigned task. High-impact or difficult-to-reverse actions should have appropriate safeguards, such as explicit approval.

5. A Simple Permission Checklist

• What information can the agent read?
• Can it create, change, share, or delete anything?
• Can it send messages, spend money, or submit forms?
• Which actions require my approval?
• Can I revoke its access?
• Are the actions logged and reviewable?

6. Try It Yourself

Choose one AI tool or connected application you already use. Open its connections or permissions settings. Identify what it can access, whether it has read-only or modification permissions, and how to disconnect it. Do not grant new access merely to complete this exercise.

7. Review Questions

1. What is the difference between an agent's capability and its permission?
2. Why might sending an email require more oversight than drafting one?
3. What does least privilege mean?

8. Interactive Knowledge Check

Question: Your agent needs to summarize an email. Which permission is most appropriate?

A. Full mailbox access, including deletion

Not the best choice. This grants unnecessary power.

B. Read access to the relevant email

Correct! The agent needs only the information required to summarize that message.

C. Permission to send emails automatically

Not necessary. Summarizing does not require sending messages.

9. What to Remember

Capability is not permission.

An AI agent should only access what it needs and perform actions it is authorized to take. Greater autonomy calls for stronger, enforceable boundaries.
