What snow_scan_vulnerabilities does on Serac
AI agents invoke snow_scan_vulnerabilities to trigger actions in Serac. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why snow_scan_vulnerabilities is rated High
A vulnerability scan is an active operation that probes systems, sends network requests, and executes detection logic. It is not a passive read — it triggers external operations whose effects depend on arguments (target scope, scan depth). It could cause service disruptions, trigger security alerts, or expose sensitive system information.
From the tool's definition "Scan for security vulnerabilities" — actively triggers a scanning operation against a target system

The rule that runs snow_scan_vulnerabilities safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Serac, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For snow_scan_vulnerabilities, this is the rule to start with:
snow_scan_vulnerabilities stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Serac, apply this rule, and every snow_scan_vulnerabilities call is checked against it from then on.
Questions about snow_scan_vulnerabilities
Scan for security vulnerabilities. It is categorised as a Execute tool in the Serac MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Serac MCP server in PolicyLayer and add a rule for snow_scan_vulnerabilities: 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 Serac. Nothing to install.
snow_scan_vulnerabilities is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the snow_scan_vulnerabilities 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 snow_scan_vulnerabilities. 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.
snow_scan_vulnerabilities is provided by the Serac MCP server (serac-labs/serac). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
