AI agents call search_vulnerabilities to retrieve information from SeldomMaster without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves vulnerability information from threat intelligence databases (likely querying resources like CVE databases, OpenCTI, or similar). It performs a lookup or search operation with no side effects on local systems or external data. No creation, modification, deletion, code execution, or financial impact is described or implied. This is a standard Read operation.
From the tool's definition The tool is named 'search_vulnerabilities' and exists on a cybersecurity threat intelligence server alongside query/fetch tools like 'fetch_web_page_curl', 'geo_for_ip', and 'find_actor'.
Documented attack patterns abuse exactly the kind of access search_vulnerabilities gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SeldomMaster, and nothing reaches the server without passing your rules. This is the rule we recommend for search_vulnerabilities:
{
"version": "1",
"default": "deny",
"tools": {
"search_vulnerabilities": {}
}
}search_vulnerabilities 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.
Name: search_vulnerabilities. It is categorised as a Read tool in the SeldomMaster MCP Server, which means it retrieves data without modifying state.
Register the SeldomMaster MCP server in PolicyLayer and add a rule for search_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 SeldomMaster. Nothing to install.
search_vulnerabilities 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 search_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 search_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.
search_vulnerabilities is provided by the SeldomMaster MCP server (paralax/seldommonster). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from SeldomMaster, 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.
