THE RISK

Low Risk

Why search_documentation needs a policy

This tool retrieves and queries existing documentation without creating, modifying, deleting, executing code, or committing financial transactions. The search operation is read-only and poses minimal risk even if an AI agent queries it without restrictions.

From the tool's definition Tool description states it 'search[es] for documentation across all known Minecraft/Fabric topics' — a pure query/retrieval operation with no side effects.

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

POLICY

How to control search_documentation

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

policy.json

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

search_documentation 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 Minecraft Dev MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
