Close the Camoufox browser and release all resources.
AI agents use close_browser 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.
An AI agent can call close_browser faster than any human can review — one bad instruction and it creates or modifies resources in Camoufox Reverse by the hundred, each call as confident as the last.
Documented attack patterns abuse exactly the kind of access close_browser 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 close_browser:
{
"version": "1",
"default": "deny",
"tools": {
"close_browser": {
"limits": [
{
"counter": "close_browser_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}close_browser 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.

Close the Camoufox browser and release all resources. 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 close_browser: 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.
close_browser 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 close_browser 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 close_browser. 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.
close_browser 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.
