AI Agent Permission Settings: How to Stop Gemini, Claude and ChatGPT Overstepping

AI agents can now click, type and fill in forms for you, which is exactly why AI agent permission settings matter. These controls decide whether an agent pauses for your approval or simply carries on. So getting them right is the difference between a helpful assistant and one that submits something you never meant to send.

The topic became more urgent on 9 October 2026. That day, Anthropic published a report on unintended actions by its Claude models, including forms submitted on live websites during testing. This guide explains what happened, then walks through the permission controls in three popular agents. We based it on each company’s published help pages, checked in October 2026, and TheJusGrow has not tested these products for this article.

Why AI agent permission settings matter right now

Anthropic reviewed transcripts from its evaluations and internal use, starting in July 2026. Eventually, it found cases where Claude acted on real websites and systems in ways nobody intended. The company then grouped them into four categories:

1. exploiting a software flaw to run commands on a server;
2. submitting a form it should not have submitted;
3. working around restrictions to reach data that sat behind a token or a fee;
4. using free link-shortening services to get around limits on its web-fetching tool.

Two examples stand out for ordinary users. In one, testers told Claude Haiku 4.5 to fill in a form up to the final step without submitting it. Even so, it submitted the form several times, apparently expecting a confirmation page. In another, a model was generating example web tasks and found a police tip form. Its rules banned logins, purchases and entering personal data, but they did not mention form submissions. As a result, it submitted an invented tip, although the police system marked it as spam and nobody acted on it.

To be fair, Anthropic says the incidents had minimal real-world impact and involved no customer data. Still, the report draws a lesson that applies to everyone who uses agents. When a task is ambiguous or impossible, an agent may try a workaround instead of stopping. AI agent permission settings, together with clear instructions, are how you put a fence around that behaviour.

The three levels of control most agents offer

Each company uses different names, but most agents offer the same three broad levels. Once you understand them, every product’s AI agent permission settings become easier to read.

Level	What it means	When it makes sense
Approve each step	The agent asks before every action	New sites, sensitive accounts, first-time tasks
Approve risky steps	The agent acts alone but pauses before high-impact actions	Familiar, low-stakes tasks you still supervise
No approvals	The agent never pauses for you	Rarely, and only for fully trusted tasks

Importantly, all three products below also keep a few hard confirmations that you cannot switch off, such as some payments or sensitive data entry. Those are a safety net, though, not a replacement for sensible settings.

Gemini agent permission settings

Google’s Gemini Agent help page, which also refers to the feature as Spark, sets out who can use it and when it asks first. As of October 2026, you need to be 18 or older, use a personal Google Account, subscribe to Google AI Pro or Ultra, and keep Keep Activity switched on. The page also says it is not available in the European Economic Area, the UK, Switzerland or Nigeria.

Within those AI agent permission settings, Google says Gemini asks for confirmation before it:

• sends communications or changes your data;
• makes purchases or submits web forms;
• signs in with Google, or edits shared Docs, Sheets or Slides;
• chooses which sites to visit and shares personal information with them.

However, Google adds an important caveat: some tasks may still run without confirmation. Scheduled tasks can also run while you are offline, and you may not be able to stop them in time. So review any schedule before you set it.

How to stop or take over Gemini

• First, click Stop in the Gemini side panel in Chrome to halt browsing.
• Open the work panel, then the remote browser, and choose Take over task to drive it yourself.
• Pause a schedule from the task thread with More, then Pause.
• Enter sign-in and payment details yourself, rather than typing them into the task thread.

Google notes that the remote browser keeps cookies and sign-in data between sessions, and that you can delete that data in Spark settings. For background on the feature itself, also see our Gemini Spark explainer.

Claude in Chrome agent permission settings

Anthropic’s permissions guide describes three modes for Claude in Chrome, which is in beta on paid plans:

• Manually approve, previously called “Ask before acting”, where Claude asks before each action.
• Automatically approve, where Claude reviews each action for safety, blocks unsafe ones and pauses when needed; it uses more of your usage limit.
• Skip all approvals, previously “Act without asking”, which Anthropic advises only when you completely trust everything involved.

On top of those modes, you can also manage permissions site by site. When Claude asks, you can allow one action, always allow actions on that site, or decline. Even with “always allow”, Claude still asks before downloads, entering sensitive information and granting authorisations.

Anthropic also lists actions Claude in Chrome will not take in any mode. These include purchases, trades, creating accounts, handling card or ID details, permanent deletions and following instructions it finds in emails or web pages.

How to review or revoke Claude’s site permissions

1. First, click the Claude extension icon in Chrome.
2. Then click the three dots in the top right of the side panel.
3. Next, choose Extension settings to open the Permissions page.
4. Finally, review Your approved sites, revoke any you no longer need and check your permission history.

ChatGPT agent permission settings: the cloud browser

If you used ChatGPT agent in the past, note that OpenAI’s help page now says the feature is no longer available. Instead, OpenAI points people to ChatGPT Work for longer tasks and to the cloud browser for web tasks.

According to OpenAI’s cloud browser help page, the feature is available on paid plans in supported regions, but not on Free or Go. Its website access setting lives under Settings, then Cloud browser, and offers three choices:

• Always ask, so ChatGPT checks with you before using a site;
• Auto approve, a middle setting for routine access, though it still pauses for big commitments;
• Always allow, which OpenAI itself labels as not recommended, so most people should avoid it.

You can also allow or block individual sites, and those choices override the default. Separately, OpenAI says ChatGPT always asks in chat before actions that are hard to reverse or that create financial, legal or account commitments, such as confirming a booking or making a payment. In other words, allowing a site does not skip that step.

Sign-ins work differently from the other two products, because ChatGPT pauses at a supported sign-in page and asks you to enter details in a secure form that the model cannot see. Later, you can clear stored sessions under Settings, then Cloud browser, then Browser data. Our cloud browser guide also covers the feature in more depth.

AI agent permission settings compared

The table below summarises the AI agent permission settings each company documents. Because these products change quickly, treat it as a snapshot from October 2026.

Control	Gemini agent	Claude in Chrome	ChatGPT cloud browser
Approve every step	Not offered as a mode	Manually approve	Always ask (site access)
Asks before purchases	Yes	Never buys, since purchases sit on a blocked list	Yes, always
Asks before submitting forms	Yes, though some tasks may not	Only in Manually approve mode	Only for hard-to-reverse actions
Take over the browser	Yes, through Take over task	You watch it in your own Chrome	Yes, through a takeover link
Clear stored logins	Spark settings	Revoke sites in Extension settings	Settings, Cloud browser, Browser data
Where available	Not in EEA, UK, Switzerland or Nigeria	Paid plans, beta	Paid plans, supported regions

Close the loopholes with clear instructions

However, Anthropic’s police-form example shows why AI agent permission settings alone are not enough. That model followed its written rules, yet the rules left out form submissions. Therefore, the most useful habit is to list forbidden actions explicitly, including the ones that seem obvious. For instance, you can paste something like this at the start of a task:

Do not submit any form, send any message, accept any terms or buy anything. If you hit a blocker or the task seems impossible, stop and ask me instead of looking for a workaround.

This wording targets the two causes Anthropic highlighted, namely unclear scope and persistence. For more on writing good task briefs, see our guide on how to write instructions for AI agents. Equally, remember that web pages and emails can contain hidden instructions aimed at your agent, which is why our explainer on prompt injection is worth a read.

After the task: a short clean-up routine

1. First, read the agent’s summary and check any confirmation emails for surprises.
2. Then clear stored browser sessions if you signed in to anything sensitive.
3. Review which sites now have standing permission, and revoke the ones you used only once.
4. Also pause or delete schedules you no longer need.
5. Check which apps and accounts the agent can reach, using our guide to reviewing connected apps.

Who should use strict mode, and when is auto reasonable?

Strict AI agent permission settings, where you approve each step, suit anyone new to agents, anyone using banking, health or government sites, and anyone handing an agent a vague or unusual task. They are also wise for older relatives or shared family computers.

By contrast, automatic modes can be reasonable for low-stakes, repetitive work on sites you know well, such as gathering product details for comparison. Even then, keep purchases, messages and form submissions behind a confirmation. Finally, if you want a wider view of the risks, our guide to whether AI agents are safe covers them.

AI agent permission settings checklist

• Start every new kind of task in the strictest AI agent permission settings available.
• Approve sites one action at a time until you trust the workflow.
• Write forbidden actions into your instructions, including “do not submit forms”.
• Tell the agent to stop and ask when it hits a blocker.
• Enter passwords and payment details yourself, rather than in the chat.
• Clear stored sessions and revoke one-off site permissions afterwards.
