AI agents call local_types 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 returns information about local types defined in a reverse engineering database. It has no side effects, does not execute code, does not modify data, and does not delete anything. It is purely informational in nature, consistent with other analysis tools like 'analyze_strings' and 'analyze_funcs' that inspect program metadata.
From the tool's definition Tool name 'local_types' with description 'List local types' indicates data retrieval from an IDA Pro database without modification or execution. The verb 'list' is a classic read operation that retrieves information about existing types.
Documented attack patterns abuse exactly the kind of access local_types 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 local_types:
{
"version": "1",
"default": "deny",
"tools": {
"local_types": {}
}
}local_types 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.
List local types. 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 local_types: 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.
local_types 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 local_types 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 local_types. 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.
local_types 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.
