AI agents call list_binaries to retrieve information from BinAssistMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to list or query available binaries, which is a read-only operation with no side effects, no code execution, and no data modification. The empty description lowers confidence slightly, but the name and context within a reverse engineering analysis toolset strongly suggest data retrieval rather than modification or execution.
From the tool's definition Tool name 'list_binaries' suggests retrieval/enumeration of binary files with no modification capability. No description provided, but naming convention and position among sibling tools (analyze_function, get_basic_blocks, get_binary_info) indicates…
Documented attack patterns abuse exactly the kind of access list_binaries gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and BinAssistMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_binaries:
{
"version": "1",
"default": "deny",
"tools": {
"list_binaries": {}
}
}list_binaries is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_binaries. It is categorised as a Read tool in the BinAssistMCP MCP Server, which means it retrieves data without modifying state.
Register the BinAssist MCP server in PolicyLayer and add a rule for list_binaries: 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 BinAssistMCP. Nothing to install.
list_binaries 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 list_binaries 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 list_binaries. 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.
list_binaries is provided by the BinAssist MCP server (symgraph/binassistmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
