AI agents call search_dotnet_types 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 tool performs a search operation, which is a Read category action. It queries .NET type information without side effects. Severity is low because searching type metadata poses minimal risk even if misused by an AI agent. Confidence is moderate (0.75) rather than high because the description is empty, requiring inference from the tool name and server context alone.
From the tool's definition Tool name 'search_dotnet_types' indicates a search/query operation on .NET type information. The name suggests reading and listing types rather than modifying, executing, or destroying data. Tool operates within Ghidra/analysis context.
Documented attack patterns abuse exactly the kind of access search_dotnet_types 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 search_dotnet_types:
{
"version": "1",
"default": "deny",
"tools": {
"search_dotnet_types": {}
}
}search_dotnet_types is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

search_dotnet_types. 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 search_dotnet_types: 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.
search_dotnet_types 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 search_dotnet_types 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 search_dotnet_types. 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.
search_dotnet_types 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.
