Extract struct/class definitions and data type information from the binary.
AI agents call get_data_structures to retrieve information from Kawaiidra MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries data structure metadata from a binary without altering the binary, creating side effects, or executing any operations. It is purely analytical/read-only. The low severity reflects that misuse by an AI agent would only risk information disclosure, not system compromise or data loss.
From the tool's definition Tool description states it 'Extract[s] struct/class definitions and data type information from the binary.' The verb 'extract' and 'get' prefix indicate pure information retrieval with no modification, creation, deletion, or execution of code.
Documented attack patterns abuse exactly the kind of access get_data_structures gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Kawaiidra MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_data_structures:
{
"version": "1",
"default": "deny",
"tools": {
"get_data_structures": {}
}
}get_data_structures is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Extract struct/class definitions and data type information from the binary. It is categorised as a Read tool in the Kawaiidra MCP MCP Server, which means it retrieves data without modifying state.
Register the Kawaiidra MCP server in PolicyLayer and add a rule for get_data_structures: 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 Kawaiidra MCP. Nothing to install.
get_data_structures 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_data_structures 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_data_structures. 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_data_structures is provided by the Kawaiidra MCP server (wagonbomb/kawaiidra-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Kawaiidra MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
