AI agents call read_struct 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.
This tool retrieves structural information from an IDA Pro database—a query operation that returns data without altering the database or triggering external operations. It fits the Read category: retrieves or queries data with no side effects. The blast radius of misuse is minimal since it only exposes existing reverse engineering metadata.
From the tool's definition Tool name 'read_struct' and description 'Read struct fields' indicate data retrieval without modification. The verb 'read' and absence of terms like 'modify', 'delete', 'create', or 'execute' confirm no side effects.
Documented attack patterns abuse exactly the kind of access read_struct 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 read_struct:
{
"version": "1",
"default": "deny",
"tools": {
"read_struct": {}
}
}read_struct is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Read struct fields. 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 read_struct: 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.
read_struct 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 read_struct 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 read_struct. 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.
read_struct 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.
