THE RISK

Why delete_data_type needs a policy

This tool permanently removes user-defined data types from a Ghidra binary analysis project. While the blast radius is limited to the analysis project itself (not production systems), the action is irreversible and destructive to analytical work. An AI agent misusing this could erase significant reverse-engineering progress.

From the tool's definition 'Delete a user-defined data type from the binary' — the verb 'Delete' combined with the irreversible nature of removing data type definitions from a binary analysis project.

POLICY

How to control delete_data_type

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 delete_data_type:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_data_type"
  ]
}

delete_data_type disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Kawaiidra MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about delete_data_type

What does the delete_data_type tool do? +

Delete a user-defined data type from the binary. It is categorised as a Destructive tool in the Kawaiidra MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on delete_data_type? +

Register the Kawaiidra MCP server in PolicyLayer and add a rule for delete_data_type: 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.

What risk level is delete_data_type? +

delete_data_type is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit delete_data_type? +

Yes. Add a rate_limit block to the delete_data_type 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.

How do I block delete_data_type completely? +

Set action: deny in the PolicyLayer policy for delete_data_type. 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.

What MCP server provides delete_data_type? +

delete_data_type 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.

Enforce policy on every Kawaiidra MCP tool call.

Start from Kawaiidra MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
