Why osrs_wiki_search needs a policy

This tool performs a search operation against a wiki database, which is a pure read operation. It retrieves matching pages based on search criteria but does not create, modify, delete, or execute any code. The blast radius of misuse is minimal—an agent could only retrieve excessive data or search for sensitive information, but cannot cause irreversible changes or access unauthorized resources.

From the tool's definition Tool name 'osrs_wiki_search' and description 'Search the OSRS Wiki for pages matching a search term' indicate a query operation that retrieves information without modification or side effects.

POLICY

How to control osrs_wiki_search

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 osrs_wiki_search:

policy.json

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

osrs_wiki_search 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.
