THE RISK

Low Risk

Why suggest_minestom_libraries needs a policy

The tool only reads and returns library suggestions, optionally fetching live GitHub topic data. It does not modify, execute, delete, or involve financial transactions. The blast radius of misuse is minimal as it only surfaces informational content.

From the tool's definition 'returns curated library suggestions' and 'add live GitHub topic results' — purely retrieves and surfaces information

POLICY

How to control suggest_minestom_libraries

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

policy.json

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

suggest_minestom_libraries 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 Minestom 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.
