Why open_library needs a policy

With no description available, it's unclear what this tool does. The name 'open_library' could suggest loading a library/binary into IDA Pro for analysis (Read), or it could have side effects. Given the context of IDA Pro reverse engineering tools, it likely opens a binary/library file for inspection, suggesting a Read or Execute action, but confidence is very low.

From the tool's definition Tool name is 'open_library' but the description is empty and uninformative.

POLICY

How to control open_library

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "open_library": {
      "limits": [
        {
          "counter": "open_library_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

open_library gets a rate cap, and everything else on the server is denied unless you say otherwise.

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