TL;DR: Local coding agents that start with browser, terminal, write, memory, and MCP access already create broad standing authority before a task begins, according to PermitIO. Zero standing permissions shifts the model to minimal baseline access plus time-limited grants, which is the practical boundary that keeps agent tool use auditable and containable.
Editorial analysis by NHI Mgmt Group, based on content published by PermitIO: “Zero Standing Permissions for AI Agents: Lessons from Hermes Blank Slate and Toolset Pinning”.
Key questions
Q: What breaks when an AI agent has blanket tool access?
A: The control boundary disappears.
Q: Why do AI agent permissions need runtime authorisation instead of only config pinning?
A: Config pinning reduces exposure, but it cannot decide whether a specific action is safe in the moment.
Q: How do teams know whether agent tokens are truly least privilege?
A: Teams know agent tokens are truly least privilege when each token maps to one narrow workload, one data domain, and one clear revocation decision.
Practitioner guidance
- Blank-slate default toolsets Start local and enterprise agents with no active sensitive tools, then enable only the minimum read capabilities needed for the first task.
- Task-scoped runtime grants Issue browser, terminal, MCP, memory, and delegation permissions only for the specific task, with automatic revocation when the task ends or times out.
- Separate pinning from authorisation Use static toolset pinning to define the baseline surface area, then add execution-time policy checks for every write, execute, delegate, or connector action.
Bottom line: AI agents that start with active browser, terminal, memory, and connector access create standing authority before the task begins, which expands the blast radius of any prompt error.

Blank-slate startup is an assumption reset, not a UI preference: the old assumption was that an AI assistant could begin with broad tool reach and still remain safe through model restraint. That assumption fails when the actor can select actions at runtime and chain tools without human pacing. The implication is that agent governance must move from trusting starting conditions to controlling every privilege boundary.
A few things that frame the scale:
- According to PwC, 79% of organizations have already adopted AI agents to some degree.
A question worth separating out:
Q: Should organisations allow terminal, memory, and MCP access by default for AI agents?
A: No. Default enablement turns convenience into standing authority, which is exactly what least-privilege design is meant to prevent. Safer practice is to keep high-risk tools disabled until needed, then grant them with short-lived scope and clear logging. That preserves productivity without normalising excess access.
