AI agents call security-scan to retrieve information from VibeCoding System without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Security scanning is a read-only operation that queries vulnerability databases and analyzes dependency metadata to identify risks. It does not execute code, modify dependencies, delete data, or trigger deployments.
From the tool's definition Tool name 'security-scan' and description 'Scan dependencies for security vulnerabilities' indicate a scanning/analysis operation that retrieves and reports vulnerability data without modifying systems or dependencies.
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 VibeCoding System, 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.
Free to start. No card required.
Scan dependencies for security vulnerabilities. It is categorised as a Read tool in the VibeCoding System MCP Server, which means it retrieves data without modifying state.
Register the VibeCoding System 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 VibeCoding System. 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 VibeCoding System MCP server (zenobia000/vibecoding-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from VibeCoding System, 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.
