AI agents call struct_info 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 metadata about data structures in the reverse engineering context. It queries and returns information without creating, modifying, deleting, or executing operations. The action is informational only, consistent with other read operations like 'analyze_funcs' and 'callgraph' on the same server. Low severity because accessing structural information poses minimal risk even if misused by an agent.
From the tool's definition Tool name is 'struct_info' and description is 'Get struct info'. The verb 'Get' indicates retrieval of existing data about structures without modification or side effects.
Documented attack patterns abuse exactly the kind of access struct_info 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 struct_info:
{
"version": "1",
"default": "deny",
"tools": {
"struct_info": {}
}
}struct_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get struct info. 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 struct_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 Ida Domain. Nothing to install.
struct_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 struct_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 struct_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.
struct_info 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.
Free to start. No card required.
