THE RISK

Low Risk

Why get_reddit_karma needs a policy

This tool performs a retrieval operation on public data (Reddit karma metrics) without side effects. It does not create, modify, delete, or execute code. The blast radius of misuse is minimal — an AI agent could only retrieve already-public user reputation data. Classified as Read with low severity.

From the tool's definition Tool retrieves 'live karma breakdown for u/${this.config.username}' — a read-only query of publicly available Reddit user statistics with no modification, deletion, or execution of external operations.

POLICY

How to control get_reddit_karma

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

policy.json

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

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