AI agents call search_url to retrieve information from Kaspersky OpenTIP MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a threat intelligence database to retrieve information about a URL. It performs a read-only lookup operation with no side effects, no data modification, and no code execution. The severity is low because threat intelligence queries have minimal blast radius—they only expose information that is already publicly available through threat intelligence feeds.
From the tool's definition Tool name 'search_url' and description 'Get threat intelligence data about a URL' indicate retrieval of existing threat intelligence information without modification, deletion, or execution of external operations.
Documented attack patterns abuse exactly the kind of access search_url gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kaspersky OpenTIP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_url:
{
"version": "1",
"default": "deny",
"tools": {
"search_url": {}
}
}search_url is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get threat intelligence data about a URL. It is categorised as a Read tool in the Kaspersky OpenTIP MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kaspersky OpenTIP MCP Server MCP server in PolicyLayer and add a rule for search_url: 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 Kaspersky OpenTIP MCP Server. Nothing to install.
search_url 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_url 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_url. 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_url is provided by the Kaspersky OpenTIP MCP Server MCP server (kasperskylab/threat-intelligence). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kaspersky OpenTIP MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
