AI Agent Least Privilege: Task Permission Scoper
Scopes here are generic patterns. The real permission names differ per vendor, so read “the equivalent permission in your platform”. Only GitHub permission names are given by name, from GitHub’s own documentation. Session lengths are PlayCISO defaults, not standards.
Read the code and issue, change files, open a pull request for review.
Your minimum scope for “Fix a bug in one repository”
Session lifetime: 60 minutes, then issue a new grant. A single fix should finish within an hour; a longer job should restart with fresh, re-approved access.

TL;DRAt a glance
4 points
- 12 task types and 7 system types. You get minimum operations, explicit denials, a session lifetime and network allow-list for each system.
- Scopes are generic patterns; real permission names differ per vendor. GitHub fine-grained permission names come from GitHub’s documentation; AWS and Google Cloud are described by the features their docs name.
- Systems you connect that the task does not need are flagged so you can drop them.
- Session lengths are PlayCISO defaults, not standards. Answers stay in your browser.
How to use the output
Start from the task, not the agent. For each system, create a credential that matches the allow list, set its expiration to the session lifetime, and deny the rest in the downstream system rather than relying on the agent to hold back. OWASP’s guidance on excessive agency recommends enforcing authorization in the downstream system for exactly that reason.
What is and is not named
GitHub’s documentation lists repository permissions such as Contents, Pull requests, Issues, Metadata, Actions, Workflows and Administration, each with read and/or write access, and says fine-grained tokens can be limited to selected repositories and given an expiration. For AWS and Google Cloud we cite the principles their pages state and avoid inventing action or role strings. For everything else, use the equivalent permission in your platform.
Frequently asked questions
What does least privilege mean for an AI agent?
Give the agent only the operations, on only the resources, for only as long as the current task needs, and issue a new grant for the next task. OWASP lists excessive functionality, excessive permissions and excessive autonomy as the root causes of excessive agency, and NIST SP 800-53 has a control family for access enforcement and least privilege.
Why scope per task and not per agent?
An agent that holds the union of every task’s permissions is exposed to all of them whenever one task is manipulated, for example by text in an email or web page. A per-task grant limits what a single bad step can reach.
Are these the real permission names?
Only for GitHub, where we list the fine-grained token permission names (such as Contents, Pull requests, Issues and Metadata) shown in GitHub’s documentation. For cloud, databases, email and ticketing, scopes are generic patterns and the real names differ per vendor, so use the equivalent permission in your platform.
What do AWS and Google Cloud recommend?
AWS recommends temporary credentials through roles, permissions limited to the task, conditions, and Access Analyzer to generate policies from observed use. Google Cloud recommends avoiding basic roles in production, using predefined or custom roles at the smallest scope, a separate service account per component and conditional bindings that expire. We cite those pages and do not invent action names.
Why does it tell me not to connect some systems?
If you tick a system that the chosen task does not need, every connection is extra blast radius if the agent is manipulated. The tool flags it so you can drop it rather than scope it.
Where do the session lifetimes come from?
They are PlayCISO defaults for reasoning with, short enough to force a fresh grant, not figures from a standard. Set your own.
Are my answers sent anywhere?
No. They stay in this browser’s local storage, and exports are built in your browser.
