Get threat intelligence information about a file by hash (md5, sha1, sha256)
AI agents call search_hash 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 by hash value and returns read-only information. It performs a lookup without side effects, making it a Read operation. Severity is low because misuse would only expose or surface existing threat data, not alter systems or data, with minimal blast radius.
From the tool's definition Tool description states 'Get threat intelligence information about a file by hash' — a retrieval operation with no modification, creation, deletion, or execution of external systems.
Documented attack patterns abuse exactly the kind of access search_hash 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_hash:
{
"version": "1",
"default": "deny",
"tools": {
"search_hash": {}
}
}search_hash is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get threat intelligence information about a file by hash (md5, sha1, sha256). 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_hash: 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_hash 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_hash 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_hash. 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_hash 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.
