AI agents call get_u64 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 performs a straightforward data retrieval operation from memory in the context of IDA Pro reverse engineering. It reads but does not modify any state, making it a Read operation. The severity is low because reading memory addresses in a controlled reverse engineering environment poses minimal risk of harm—the worst outcome would be access to information already available through the IDA database.
From the tool's definition Tool description explicitly states 'Read 64-bit unsigned integers from memory addresses' — a read operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_u64 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 get_u64:
{
"version": "1",
"default": "deny",
"tools": {
"get_u64": {}
}
}get_u64 is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Read 64-bit unsigned integers from memory addresses. 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 get_u64: 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.
get_u64 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_u64 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_u64. 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_u64 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.
