AI agents call get_function_callers to retrieve information from Binary MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to perform static or dynamic analysis to identify which functions call a given function—a read-only inspection operation with no side effects on the binary or system state. While the description is empty, the name and sibling tools (analyze_*, decompile_*, check_*) suggest this server is focused on analysis rather than modification.
From the tool's definition Tool name 'get_function_callers' indicates a query operation that retrieves caller information for a function. The server context involves binary analysis tools (Ghidra, x64dbg, WinDbg, ILSpyCmd) where introspection and analysis are primary use cases.
Documented attack patterns abuse exactly the kind of access get_function_callers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Binary MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_function_callers:
{
"version": "1",
"default": "deny",
"tools": {
"get_function_callers": {}
}
}get_function_callers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_function_callers. It is categorised as a Read tool in the Binary MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Binary MCP Server MCP server in PolicyLayer and add a rule for get_function_callers: 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 Binary MCP Server. Nothing to install.
get_function_callers 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 get_function_callers 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 get_function_callers. 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.
get_function_callers is provided by the Binary MCP Server MCP server (sarks0/binary-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Binary MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
