AI agents call basic_blocks 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.
In static analysis and reverse engineering, basic blocks are fundamental code units retrieved for analysis. The tool appears to query existing IDA database information (control flow analysis) without creating, modifying, or deleting data. The surrounding tools on this server (analyze_*, callgraph, callers) are all Read operations.
From the tool's definition Tool is part of IDA Pro's reverse engineering suite alongside tools like analyze_funcs, analyze_strings, callees, callers, and callgraph which are inherently read-only analysis tools.
Documented attack patterns abuse exactly the kind of access basic_blocks 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 basic_blocks:
{
"version": "1",
"default": "deny",
"tools": {
"basic_blocks": {}
}
}basic_blocks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

basic_blocks. 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 basic_blocks: 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.
basic_blocks 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 basic_blocks 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 basic_blocks. 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.
basic_blocks 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.
