AI agents call network_capture_full to retrieve information from OpenChrome without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool captures and retrieves network traffic including response bodies, which is fundamentally a Read/monitoring operation. However, it carries medium severity because it can intercept sensitive data (auth tokens, credentials, API responses) passing through the browser. The 'clear' action is minor and reversible. No code execution or data modification is performed.

Documented attack patterns abuse exactly the kind of access network_capture_full gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OpenChrome, and nothing reaches the server without passing your rules. This is the rule we recommend for network_capture_full:
{
"version": "1",
"default": "deny",
"tools": {
"network_capture_full": {}
}
}network_capture_full is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Capture network requests with response bodies (capped). Actions: start, stop, getLogs, clear. Bodies over maxBodyBytes are omitted with reason=. It is categorised as a Read tool in the OpenChrome MCP Server, which means it retrieves data without modifying state.
Register the OpenChrome MCP server in PolicyLayer and add a rule for network_capture_full: 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 OpenChrome. Nothing to install.
network_capture_full 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 network_capture_full 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 network_capture_full. 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.
network_capture_full is provided by the OpenChrome MCP server (shaun0927/openchrome). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
