get_documentation

THE RISK

Low Risk

Why get_documentation needs a policy

This tool retrieves and displays documentation and reference information. It has no side effects, does not modify any data, does not execute code, and does not perform destructive operations. It is a straightforward read operation that returns existing documentation content to assist developers in understanding Minecraft classes and concepts.

From the tool's definition Tool description states it 'Get[s] documentation' and 'Links to Fabric Wiki, Minecraft Wiki, and provides usage hints' — purely informational retrieval with no modification, deletion, or execution of code.

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

POLICY

How to control get_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 get_documentation:

policy.json

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

get_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.
