AI agents call pseudo_rust 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 pseudo code representations of functions from a binary analysis context. It performs analysis and visualization of existing binary data without modifying the binary, executing code, or causing side effects. It is a read-only query operation similar to the sibling tools like 'disassembly' and 'get_functions' on the same server, which are inspection/analysis tools.
From the tool's definition Tool name 'pseudo_rust' and description 'Get pseudo Rust code of a specified function' indicate a retrieval operation that generates decompiled/pseudo code representation of binary functions. No modification, execution, or deletion occurs.
Documented attack patterns abuse exactly the kind of access pseudo_rust 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 pseudo_rust:
{
"version": "1",
"default": "deny",
"tools": {
"pseudo_rust": {}
}
}pseudo_rust 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.
Get pseudo Rust code 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 pseudo_rust: 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.
pseudo_rust 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 pseudo_rust 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 pseudo_rust. 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.
pseudo_rust 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.
