Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesGive a local AI agent only the files and app actions it needs, and enforce those limits outside the model—with an OS sandbox or virtual machine, narrow file mounts, restricted network access, scoped credentials, and human review for consequential actions. A prompt telling an agent to be careful is not a substitute for restricting what its execution environment can reach.
What safe access means
An agent can generally act on resources available to its execution environment: files, credentials, network destinations, and tools connected to apps. Safety therefore depends on limiting those resources before the task begins, then checking how the limits behave in the configuration you actually run.
OpenAI describes the relationship succinctly: “Approvals and sandboxing work together.” Sandboxing defines the technical execution boundary; approval policy governs actions that cross it. Neither replaces the other, and an app’s permission scopes are a separate control.
Set up access in this order
-
Choose the task’s data and apps
Write down the specific project folder, documents, and app functions the task requires. Keep unrelated personal files, account data, and secrets out of scope. If the agent only needs to analyze a document, do not grant a whole home directory or broad app access.

- 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
-
Choose an enforced boundary
Prefer an OS-enforced sandbox or virtual machine over instructions alone. Check what the boundary actually isolates: processes, files, network access, and connected tools can be governed differently. Vendor features and defaults vary by product and release.
-
Limit filesystem access
For analysis, use read-only access where possible. For edits, prefer a disposable clone or a dedicated workspace with version control and backups. Confirm whether the agent sees a read-only copy, a private working clone, or a live read-write view of host files.

![[2 Pack] 24 Inch Computer Privacy Screen Filter for 16:9 Widescreen Monitor](https://m.media-amazon.com/images/I/41SBKw3J4ML._SL160_.jpg)

Even after prolonged use, you will get a brand new privacy screen for your desktop computer monitor after cleaning. Very Durable!
That distinction matters: changes to a direct writable mount can appear on the host immediately, even if the rest of the host is isolated. Docker’s documentation distinguishes direct mounts from clone mode, where the repository is mounted read-only and the agent works on a private clone. Also inspect symlinks and hidden or configuration files within the mounted tree; isolation outside the boundary does not protect files you deliberately exposed inside it.
-
Set network rules independently
Begin with network access disabled or deny-by-default, then allow only the destinations and methods the task needs. Recheck wildcard or broad allow rules. A sandbox with unrestricted outbound access can still transmit data it can read.

Treat fetched pages and tool results as untrusted input. A web page or document can contain instructions that conflict with your intent; it should not be allowed to expand the agent’s permissions.
-
Keep credentials out of reach where possible
Avoid placing long-lived secrets in files or environment variables visible to the agent. Use narrowly scoped credentials where an integration requires them. Docker documents a host-side proxy that can inject authentication headers into outbound requests without exposing the raw credential values inside its sandbox VM.

-
Grant app and tool permissions narrowly
Start with read-only app access when available. For actions that write, send, delete, purchase, or publish, retain a human confirmation step if the integration supports it. App scopes determine what an integration can do; approval prompts govern whether a person must review an action; the sandbox limits execution resources. These controls address different risks.
-
Check where integrations run
Do not assume every tool is inside the agent’s sandbox. Docker documents that local stdio MCP servers run as host processes outside the sandbox VM and advises users to “Treat local MCP servers as trusted host integrations.” Review a local server’s source, command, arguments, environment variables, and exposed tools. A host-run server may have the permissions of the host process, not the narrower permissions you expected from the agent VM.

Test the boundary, then review and revoke
Use harmless sample data first. Verify that prohibited paths are inaccessible, disallowed network requests fail, intended tools work, and confirmation prompts appear for consequential operations. Then inspect file diffs, app audit trails, and network activity where available. Revoke access when the task is finished and remove temporary mounts or credentials.
Compare approaches by their actual boundaries
Product labels such as “sandbox” do not establish what a particular setup protects. Compare the configuration across these dimensions before choosing it:
| Control | What to compare |
|---|---|
| Isolation boundary | Prompt-only instructions, process or container controls, or a VM/OS-enforced boundary. |
| Filesystem scope | No host files, a read-only copy, a private clone, or a live read-write mount. |
| Network policy | Disabled access, deny-by-default allowlisting, or broad general access. |
| Credential handling | Raw secrets visible in the agent environment versus scoped credentials or host-side injection. |
| Apps and MCP | Permission scopes, tool-level approvals, server provenance, and whether a server executes on the host. |
| Review and recovery | Clear approval prompts, logs, version control, backups, and straightforward revocation. |
Docker Sandboxes are one documented implementation: Docker describes a local microVM model with workspace, network, credential-proxy, and MCP controls. Its documentation says local CLI and compute are free for commercial use; cloud compute is pay-as-you-go, and model-provider charges are separate. These product details do not guarantee that every configuration is secure. OpenAI’s guidance also emphasizes designing agent systems so authentication, billing, audit logging, human review, and recovery state can remain outside the container.
What to verify before a real task
- Which exact paths are mounted, and are they read-only, cloned, or writable on the host?
- Can symlinks or hidden configuration files expose more than the intended project?
- Which network destinations are allowed, and are wildcard rules broader than necessary?
- Where are credentials stored, and can the agent read their raw values?
- Which app scopes and tool actions are enabled, and which require human confirmation?
- Does each MCP server run in the sandbox, remotely, or as a local host process?
- Can you inspect changes and logs, restore prior files, and revoke access promptly?
These checks are configuration-specific. OpenAI and Docker document controls for their own systems, not universal guarantees for every agent, operating system, or integration.
