AI agents call find_insns to retrieve information from Ida Domain without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool is used for locating or retrieving instruction information from a reverse engineering database. This is a fundamentally read-only operation that does not modify, delete, or execute code. Even though the description is empty, the naming convention and context of IDA Pro tools strongly indicate this is a query/search function.
From the tool's definition Tool name 'find_insns' suggests searching for instructions within a binary database. In IDA Pro context, this is a query/search operation with no side effects.
Documented attack patterns abuse exactly the kind of access find_insns gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ida Domain, and nothing reaches the server without passing your rules. This is the rule we recommend for find_insns:
{
"version": "1",
"default": "deny",
"tools": {
"find_insns": {}
}
}find_insns is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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