AI agents call sessionstorage_get to retrieve information from MCP Camoufox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves session storage data from the browser without modifying, deleting, or executing any operations. It is a pure read operation that queries stored key-value pairs. While the parent server is designed for 'undetectable web automation' and 'bypassing bot detection,' this specific tool only accesses data, not creates, modifies, deletes, or executes code.
From the tool's definition Tool name 'sessionstorage_get' and description 'Get all sessionStorage data or a specific key' indicate retrieval operations with no modification or deletion. The verb 'Get' explicitly describes a read-only action.
Documented attack patterns abuse exactly the kind of access sessionstorage_get 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 sessionstorage_get:
{
"version": "1",
"default": "deny",
"tools": {
"sessionstorage_get": {}
}
}sessionstorage_get is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all sessionStorage data or a specific key. It is categorised as a Read tool in the MCP Camoufox MCP Server, which means it retrieves data without modifying state.
Register the MCP Camoufox MCP server in PolicyLayer and add a rule for sessionstorage_get: 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.
sessionstorage_get is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the sessionstorage_get 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 sessionstorage_get. 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.
sessionstorage_get 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.
Free to start. No card required.
