AI agents call get_param_sinks 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.
The 'get_' prefix and 'sinks' terminology (a static analysis concept) suggest this tool retrieves existing information about potential security sinks in function parameters without modifying, executing, or deleting anything. No side effects are implied. The lack of a description reduces confidence from high to medium-high, but the semantic context of binary analysis tools supports a Read classification.
From the tool's definition Tool name 'get_param_sinks' suggests retrieval of parameter sink data. The description is empty, limiting confidence, but the name pattern 'get_*' and context within a binary analysis server (alongside tools like analyze_*, check_*, decompile_*) indicates…
Documented attack patterns abuse exactly the kind of access get_param_sinks 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_param_sinks:
{
"version": "1",
"default": "deny",
"tools": {
"get_param_sinks": {}
}
}get_param_sinks is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_param_sinks. 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_param_sinks: 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_param_sinks 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_param_sinks 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_param_sinks. 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_param_sinks 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.
