WHAT IT DOES

What interceptor_camoufox_close does on Proxy

AI agents call interceptor_camoufox_close to permanently remove resources in Proxy — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

Why interceptor_camoufox_close needs a policy

The tool irreversibly destroys running processes and removes directories/files (temp launcher dir, NSS profile dir). Deletion of files and killing processes cannot be undone, placing this in the Destructive category. Severity is medium as it affects a browser instance and associated profile data, but is scoped to a single session.

From the tool's definition Close a camoufox instance...Kills the Python launcher, removes the temp launcher dir, and removes the NSS profile dir if one was created.

POLICY

How to control interceptor_camoufox_close

PolicyLayer is an MCP gateway — it sits between your AI agents and Proxy, and nothing reaches the server without passing your rules. This is the rule we recommend for interceptor_camoufox_close:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "interceptor_camoufox_close"
  ]
}

interceptor_camoufox_close disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Proxy — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
