Extract IOCs (IPs, domains, URLs, hashes, registry keys, etc.) from text.
AI agents call extract_iocs to retrieve information from REMnux MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool analyzes and extracts indicators of compromise from provided text—a read-only data retrieval operation. It has no side effects: it does not execute code, modify files, delete data, or move money. Even though it operates in a malware analysis context, the extraction itself is a passive analytical function.
From the tool's definition Tool name is 'extract_iocs' and description states it 'Extract[s] IOCs (IPs, domains, URLs, hashes, registry keys, etc.) from text.' This is a parsing/extraction operation that retrieves structured data from input without modifying, deleting, or executing…
Documented attack patterns abuse exactly the kind of access extract_iocs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and REMnux MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for extract_iocs:
{
"version": "1",
"default": "deny",
"tools": {
"extract_iocs": {}
}
}extract_iocs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Extract IOCs (IPs, domains, URLs, hashes, registry keys, etc.) from text. It is categorised as a Read tool in the REMnux MCP Server MCP Server, which means it retrieves data without modifying state.
Register the REMnux MCP Server MCP server in PolicyLayer and add a rule for extract_iocs: 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 REMnux MCP Server. Nothing to install.
extract_iocs 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 extract_iocs 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 extract_iocs. 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.
extract_iocs is provided by the REMnux MCP Server MCP server (remnux/remnux-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
