What cursor_func does on Ida Domain

AI agents call cursor_func to retrieve information from Ida Domain without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why cursor_func needs a policy

This tool performs a simple information retrieval operation typical of debugging/analysis workflows. It queries the current state of IDA Pro to return function metadata, with no side effects, data modification, or external operations. The low severity reflects minimal blast radius—misuse would only return information already accessible within the IDA environment.

From the tool's definition Tool name 'cursor_func' and description 'Get current function' indicate a read-only query operation that retrieves information about the currently selected function in IDA Pro without modifying any state.

How to control cursor_func

PolicyLayer is an MCP gateway — it sits between your AI agents and Ida Domain, and nothing reaches the server without passing your rules. This is the rule we recommend for cursor_func:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "cursor_func": {}
  }
}

cursor_func is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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