Import browser state from a JSON file by creating a new context. Args: state_path: Path to the state JSON file (exported by export_state). Returns: dict with status and the new context name.
AI agents use import_state to create or update resources in Camoufox Reverse — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Camoufox Reverse environment.
This tool performs a reversible modification operation by importing/restoring browser state (cookies, storage, sessions) from an external file. While it doesn't permanently delete data, it writes and overwrites browser context state. Given the anti-detection purpose of the server, importing a crafted state could enable credential injection, session hijacking, or automated abuse of web services.
From the tool's definition The tool 'import_state' creates a new context by loading browser state from a JSON file, which modifies the browser's internal state including cookies, local storage, and session data. This is a write operation that alters the browser environment.
Documented attack patterns abuse exactly the kind of access import_state gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Camoufox Reverse, and nothing reaches the server without passing your rules. This is the rule we recommend for import_state:
{
"version": "1",
"default": "deny",
"tools": {
"import_state": {
"limits": [
{
"counter": "import_state_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}import_state stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Import browser state from a JSON file by creating a new context. Args: state_path: Path to the state JSON file (exported by export_state). Returns: dict with status and the new context name. It is categorised as a Write tool in the Camoufox Reverse MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Camoufox Reverse MCP server in PolicyLayer and add a rule for import_state: 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 Camoufox Reverse. Nothing to install.
import_state is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the import_state 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 import_state. 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.
import_state is provided by the Camoufox Reverse MCP server (whitenightshadow/camoufox-reverse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
