Scan for security vulnerabilities in console and network traffic
AI agents call security_scan to retrieve information from Browser Connect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes security data from browser console and network logs. It has no capability to modify state, execute code, delete data, or commit financial transactions. The blast radius of misuse is limited to information disclosure (e.g., exposing sensitive data already in console/network logs), making it a Read operation with low severity.
From the tool's definition Tool performs 'scan for security vulnerabilities' which is passive analysis of console and network traffic. The verb 'scan' indicates inspection and querying of existing data with no modification, execution, or deletion.
Documented attack patterns abuse exactly the kind of access security_scan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Browser Connect, and nothing reaches the server without passing your rules. This is the rule we recommend for security_scan:
{
"version": "1",
"default": "deny",
"tools": {
"security_scan": {}
}
}security_scan is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Scan for security vulnerabilities in console and network traffic. It is categorised as a Read tool in the Browser Connect MCP Server, which means it retrieves data without modifying state.
Register the Browser Connect MCP server in PolicyLayer and add a rule for security_scan: 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 Browser Connect. Nothing to install.
security_scan 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 security_scan 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 security_scan. 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.
security_scan is provided by the Browser Connect MCP server (perception30/browser-connect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Browser Connect, 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.
