Import cookies from JSON (from cookie_export). Restores session state.
AI agents use cookie_import to create or update resources in MCP Camoufox — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Camoufox environment.
This tool writes/modifies session state by importing cookies, making it a Write operation rather than Read. While cookies can be considered part of session state, importing them is a reversible modification.
From the tool's definition Tool description states it 'Import cookies from JSON' and 'Restores session state', which modifies browser state by writing cookie data.
Documented attack patterns abuse exactly the kind of access cookie_import 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 cookie_import:
{
"version": "1",
"default": "deny",
"tools": {
"cookie_import": {
"limits": [
{
"counter": "cookie_import_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}cookie_import 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 cookies from JSON (from cookie_export). Restores session state. It is categorised as a Write tool in the MCP Camoufox MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP Camoufox MCP server in PolicyLayer and add a rule for cookie_import: 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.
cookie_import 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 cookie_import 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 cookie_import. 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.
cookie_import 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.
