AI agents call high_level_il to retrieve information from Binaryninja without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays the high-level intermediate language representation of a function within Binary Ninja, which is a read-only analytical operation. It has no side effects on the binary, the analysis environment, or any external systems. Even though Binary Ninja is a reverse engineering tool, retrieval of decompiled/IL code does not constitute execution of code or modification of state.
From the tool's definition Tool description states 'Get high level IL of a specified function' — a retrieval operation with no modification, creation, deletion, or execution capability. The verb 'Get' indicates a read-only query operation.
Documented attack patterns abuse exactly the kind of access high_level_il gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Binaryninja, and nothing reaches the server without passing your rules. This is the rule we recommend for high_level_il:
{
"version": "1",
"default": "deny",
"tools": {
"high_level_il": {}
}
}high_level_il is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get high level IL of a specified function. It is categorised as a Read tool in the Binaryninja MCP Server, which means it retrieves data without modifying state.
Register the Binaryninja MCP server in PolicyLayer and add a rule for high_level_il: 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 Binaryninja. Nothing to install.
high_level_il 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 high_level_il 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 high_level_il. 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.
high_level_il is provided by the Binaryninja MCP server (mcpphalanx/binaryninja-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Binaryninja, 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.
