AI agents call get_file_info to retrieve information from YaraFlux MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix and 'info' suffix indicate a data retrieval operation with no side effects. While the description is empty (lowering confidence slightly), the tool name and sibling context (other get_* tools being read-only information retrievers) strongly suggest this retrieves file metadata. No capability to delete, modify, execute, or transfer funds.
From the tool's definition Tool name 'get_file_info' follows read-pattern naming convention. No description provided, but within a YARA threat analysis server context, retrieval of file metadata/information aligns with Read operations (analogous to 'get_scan_result',…
Documented attack patterns abuse exactly the kind of access get_file_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and YaraFlux MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_file_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_file_info": {}
}
}get_file_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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