AI agents call get_functions_advanced 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.
The tool retrieves or queries function information from a binary file. No description was provided, lowering confidence slightly, but the naming pattern and context of sibling read-only analysis tools strongly indicate this performs query/fetch operations only. There is no indication of modification, execution, deletion, or financial impact. Read classification is appropriate with medium-high confidence.
From the tool's definition Tool name 'get_functions_advanced' indicates retrieval of function metadata from binary analysis. Sibling tools like 'analyze_function', 'get_basic_blocks', and 'get_binary_info' are all read-only analysis operations.
Documented attack patterns abuse exactly the kind of access get_functions_advanced 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 get_functions_advanced:
{
"version": "1",
"default": "deny",
"tools": {
"get_functions_advanced": {}
}
}get_functions_advanced is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_functions_advanced. 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 get_functions_advanced: 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.
get_functions_advanced 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_functions_advanced 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_functions_advanced. 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_functions_advanced 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.
