AI agents call get_u8 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 read-only query of memory at specified addresses within IDA Pro's analysis context. It retrieves data without modifying, deleting, or executing anything. The read operation is non-destructive and has no external side effects, fitting squarely into the Read category with low severity since it only queries existing data in a controlled reverse-engineering environment.
From the tool's definition Tool name 'get_u8' and description 'Read 8-bit unsigned integers from memory addresses' explicitly indicate data retrieval with no side effects.
Documented attack patterns abuse exactly the kind of access get_u8 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_u8:
{
"version": "1",
"default": "deny",
"tools": {
"get_u8": {}
}
}get_u8 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 8-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_u8: 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_u8 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_u8 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_u8. 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_u8 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.
