AI agents call idb_meta 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 from an IDA Pro database (IDB file) with no side effects. Metadata queries do not alter, execute, or delete data. Sibling tools like 'close_database' and 'analyze_funcs' suggest this server performs reverse engineering analysis, but 'idb_meta' itself is clearly a retrieval operation, placing it in the Read category with low severity as it only exposes information about the database…
From the tool's definition Tool name 'idb_meta' and description 'Get IDB metadata' indicate retrieval of database metadata without modification. The verb 'Get' is a read-only operation.
Documented attack patterns abuse exactly the kind of access idb_meta 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 idb_meta:
{
"version": "1",
"default": "deny",
"tools": {
"idb_meta": {}
}
}idb_meta is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get IDB metadata. 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 idb_meta: 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.
idb_meta 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 idb_meta 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 idb_meta. 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.
idb_meta 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.
