THE RISK

Medium Risk

Why rename_data needs a policy

Renaming a data label is a reversible modification operation that changes an annotation or symbol name in a binary analysis context. This is clearly a Write action—it modifies project state but does not execute external code, delete data permanently, or move financial resources.

From the tool's definition Tool is named 'rename_data' and described as 'Rename a data label at a specified address.' The action modifies metadata (label names) within a Ghidra binary analysis project without deleting or irreversibly destroying data.

Documented attack patterns abuse exactly the kind of access rename_data gives an agent:

POLICY

How to control rename_data

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 rename_data:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "rename_data": {
      "limits": [
        {
          "counter": "rename_data_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

rename_data stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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 rename_data

What does the rename_data tool do? +

Rename a data label at a specified address. It is categorised as a Write tool in the Kawaiidra MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on rename_data? +

Register the Kawaiidra MCP server in PolicyLayer and add a rule for rename_data: 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 rename_data? +

rename_data is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit rename_data? +

Yes. Add a rate_limit block to the rename_data 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 rename_data completely? +

Set action: deny in the PolicyLayer policy for rename_data. 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 rename_data? +

rename_data 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.
