THE RISK

Low Risk

Why search_iftypes needs a policy

This tool retrieves interface definition data from a game data file without any side effects. Searching a data file is a read-only operation that does not create, modify, delete, or execute anything. The low severity reflects minimal risk from misuse—returning game interface definitions cannot harm systems or player data. High confidence due to clear read-only semantics in both name and description.

From the tool's definition Tool name 'search_iftypes' and description 'Search the iftypes.txt file for interface definitions' indicate a query/search operation over static game data with no modification or execution capability.

POLICY

How to control search_iftypes

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_iftypes": {}
  }
}

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

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