AI agents call get_global_value 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 queries and retrieves global variable values from a reverse-engineered binary database without modifying, deleting, or executing any code. It has no side effects beyond returning information. It is purely informational/analytical in nature, consistent with other sibling tools like analyze_funcs and analyze_strings which are typical read-only reverse engineering analysis tools.
From the tool's definition Tool description states: 'Read global variable values by address or name'. The verb 'Read' and the passive retrieval of existing global variable data with no modification capability indicates a data retrieval operation.
Documented attack patterns abuse exactly the kind of access get_global_value 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_global_value:
{
"version": "1",
"default": "deny",
"tools": {
"get_global_value": {}
}
}get_global_value 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 global variable values by address or name. 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_global_value: 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_global_value 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_global_value 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_global_value. 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_global_value 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.
