AI agents call localstorage_clear to permanently remove resources in MCP Camoufox — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently and irreversibly removes all localStorage data, which constitutes destructive action. While the data is typically recoverable from backups, the tool itself performs a non-undoable deletion operation.
From the tool's definition Tool name 'localstorage_clear' and description 'Clear all localStorage' indicate irreversible deletion of client-side storage data.
Risk signalsBulk/mass operation — affects multiple targets
Documented attack patterns abuse exactly the kind of access localstorage_clear gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Camoufox, and nothing reaches the server without passing your rules. This is the rule we recommend for localstorage_clear:
{
"version": "1",
"default": "deny",
"hide": [
"localstorage_clear"
]
}localstorage_clear disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Clear all localStorage. It is categorised as a Destructive tool in the MCP Camoufox MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Camoufox MCP server in PolicyLayer and add a rule for localstorage_clear: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Camoufox. Nothing to install.
localstorage_clear is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the localstorage_clear rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for localstorage_clear. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
localstorage_clear is provided by the MCP Camoufox MCP server (robithyusuf/mcp-camoufox). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Camoufox, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
